 the Amiga is for a large group of materials championing the Amiga name to make their way into the public eye. It has been difficult for this machine to grow in the general public's awareness without openly recognizable support by third party developers on dealers' shelves. The word Macintosh has been registered and licensed by Apple Computer. Yet those developers who have neither the time nor the resources to license "Macintosh" have used the term "Mac". It is unfortunate the Amiga has not had a similar title to use. Oh yes, there have been some attempts by Amiga developers to use "Ami", but either through lack of marketing or lack of interest, the "Ami" title is Iiule known outside the already converted Amiga community. Amiga is it. It appears that Commodore's slow reaction in securing their rights in this matter could leave them unprotected. The consumer can lose 100, as there is no control of the style, type, or nature of those who may use the AMIGA name. MIGA TOWER ROLLING AMIGA . ". 'Ill So why have we joed these ranks? In truth, we have not. The title of our magazine remains Amazing Computing. We have always been "for the Commodore Amiga". We have read through the specifications Commodore wishes all developers to follow, and have followed them all to the best of our knowledge, except one: "Use Commodore trademarks as a brand name or a proper adjective and not as a noun, verb, possessive, plural, or in a generic sense." Commodore wants us all to refer to the Amiga as "the Amiga computer", and not just "the Amiga." Unfortunately for Commodore, this is not only impossible to control, since virtually everyone refers to the Amiga (see) in this way, but there is only one Amiga, therefore it is redundant to say "the Amiga computer."

Well, Amazing Computing has changed its look, at least a little. Though the alteration on our front cover may appear slight, it nonetheless represents a remarkable amount of discussion, frustration, and disbelief.
Some of you must be wondering, "Why the change?”. Others might be wondering why it took us so long to add “AMIGA” to our title. There are, of course, those who might just be asking, “Who cares?” Changing or altering the title of a publication that is enjoyed and read by so many Amiga users is not an easy thing to do. We are continually concerned that our readers may interpret any change as an abandonment of our traditional goals.
This is hardly the case. While we will continue to grow, we will never change those things which have made Amazing Computing your favorite Amiga magazine.
AC was built upon two basic policies:
1. To provide Amiga users with a tool with which to learn and do
more with their machines by establishing an expanding
reference to the Amiga and its capabilities.
No one can fault Amazing Computing on these efforts. AC has provided increasing amounts of editorial content. Each issue of AC is decidedly larger than any of our competitors'. Our articles continue to be full length. We always ask that our authors take as much time as they need to "tell their tale.” We never specify' constraining page limits, preferring instead that our authors include as much of their expertise as possible.
2 To put the amazement back into computing. When Commodore introduced the Amiga, it was the first machine we had seen in a long time that users could get excited about in such dramatically new directions. Not only could the Amiga do everything the other computers could, but it could do it faster, in color, and, via multitasking, it could do more than one thing at a time. We have taken a bit of teasing for using the word “amazing” in our title.
However, amazing remains the best adjective to describe the Amiga, Our continued goal is to bring this amazement to each reader. We have accomplished this in part by allowing our authors to select articles and reviews according to their interests. Rarely does AC's editorial staff direct or assign topics. We want our authors to be fully committed to the topic of their choice and, in the process, pass their excitement on to the reader.
So why change? We want to be more easily recognizable to the general public.
We want to reach more Amiga users. We want the public to realize the full capabilities of this machine.
So what is the problem'* Commodore.
AMIGA as seen by Commodore Since the Amiga was launched Commodore Business Machines has maintained complete control of the “AMIGA” trademark. Any new developers who wished to use the word "Amiga" in the title of their new product were quickly instructed to find another title.
The obvious exception was “AmigaWorld”, published by IDG Communications. From conversations we have had with both IDG and Commodore executives, IDG was granted the use of the trademarked name AMIGA under the condition that they would provide a magazine in time for the Amiga’s debut. AmigaWorld's first issue was on lime. Therefore, they earned the right to the title.
IDG Communications took an incredible gamble in releasing a publication for a computer which was not even in full production. Yet, they were convinced of the Amiga's ability and iDG gained advanced placement in the market as sole contender to a large group of computer enthusiasts anxious to know more about this new computer from Commodore. IDG stood alone for some time as the only third party supplier with anything to sell to the Amiga market.
AC published its first issue some six months later. Although AmigaWorld was certainly a very pretty publication, we did not believe it was catering to the majority of Amiga users. AmigaWorld was not providing what these users needed or wanted information. The immediate acceptance of AC by the Amiga community was proof that we were on the right track.
We would have included AMIGA in our title had we received an OK from Commodore. However, we were told early on in our preparation that AMIGA was not to be licensed or franchised to any additional third parties. No one else would ever be given the right to use AMIGA in their titles.
Since then, we have seen software and hardware developers continually be turned down by CBM in their requests and, until now, we were quite content to continue our work under these constraints. However, things change.

GREAT VALLEY PRODUCTS INC. PLANK AVENUE, PAOLI, PA 19301 TEL (215) 889-9411 FAX (215) 889-9416 Newsletters and even small publications began appearing with AMIGA in their title, We watched, wondering when Commodore would step in and safeguard their right. Nothing happened. When I spoke with an editor front a small publication last year and asked him how he had obtained the right to put AMIGA in his title, he chuckled and said he had a personal agreement with one of the top executives at Commodore.
In the past year, more software and hardware developers have been turned down in their quest to use the word "Amiga". Still, publications continue to sprout and take the name. I decided to contact Commodore directly, requesting the right to do what everyone else was doing place AMIGA in our title to make us more recognizable to die general public. We were told no one had acquired the right to use the trademarked name.
There must be some mistake. Sitting on my desk were no less than four US publications as well as a larger group of foreign publications and newsletters with AMIGA in their title. Meanwhile, I was informed that the executive in charge of trademarks at Commodore was unaware of any such violations.
After several months of contacting different executives at Commodore, I was told that steps wrere being taken to make sure people used the name correcdy. When 1 pointed out that some of these publications were now in production, and diat it may be too late to stop the widespread general use of AMIGA as an open term, I was assured that letters were in die mail and that a licensing agreement plan was in the works.
Since a license to use AMIGA in our title was all I wanted, I asked how could AC apply. I was told I could write a letter to Commodore’s legal department, requesting the license. They would review the request and make a decision.
This seemed to be a suitable solution. I then asked how' the selection and approval would be handled. I was informed that special preferences would be granted to those companies already making use of the title. The speaker stressed that it was only fair that these individuals receive first rights due to their sizable investments. I w'as then told that only a few such agreements would be allowed.
In short, those organizations which side stepped or completely ignored Commodore Business Machines' rights to AMIGA would be the first groups sanctioned to use the term, Those groups and companies who refrained from taking the "easy road" of product recognition may never have the right made available to them.
Product Recognition Please do not misunderstand our intentions. The best thing that could happen to die Amiga is for a large group of materials championing the Amiga name to make their wray into the public eye. It has been difficult for diis machine to grow' in the general public’s awareness without openly recognizable support by third party developers on dealers’ shelves.
The w'ord Macintosh has been registered and licensed by Apple Computer. Yet those developers who have neither the time nor the resources to license "Macintosh" have used the term "Mac". It is unfortunate die Amiga has not had a similar title to use. Oh yes, there have been some attempts by Amiga developers to use “Ami", but eidter through lack of marketing or lack of interest, the “Ami” title is little known outside the already converted Amiga community.
Amiga is it. It appears diat Commodore's slow reaction in securing their rights in this matter could leave them unprotected. The consumer can lose too, as there is no control of the style, type, or nature of those who may use the AMIGA name.
So why have we joined these ranks?
In truth, we have not. The tide of our magazine remains Amazing Computing.
We have always been "for the Commodore Amiga". We have read through the specifications Commodore wishes all developers to follow, and have followred them all to die best of our knowledge, except one: “Use Commodore trademarks as a brand name or a proper adjective and not as a noun, verb, possessive, plural, or in a generic sense."
Commodore wants us all to refer to the Amiga as “the Amiga computer", and not just “the Amiga.” Unfortunately for Commodore, this is not only impossible to control, since virtually everyone refers to the Amiga (see) in this way, but there is only one Amiga, therefore it is redundant to say “the Amiga computer."
Amiga is the computer.
Is there a solution? I am afraid not.
Commodore, blessed or otherwise, now-' has a rather large string of products by third party developers who will continue to use the AMIGA name. This gadiering crow'd should help sell Amigas to the general public as they become aware of the Amiga's (I did it again!) Popularity.
Commodore, lacking the foresight to correctly monitor the use of their computer’s name, may have seen these rights forfeited. Commodore has an obligation to maintain their trademark (have you ever seen those ads for Xerox® reminding you to refer to a photostat as a photostat). If they do not administer this right fairly and consistendv, they run the risk of losing their right.
In some wrays, this could help the Amiga community. However, in other respects, it is a very unfortunate turn of events.

Amazing Mail Dear Amazing Computing: We just received our spring Product Guide and what a fine job it is! It is obvious that a lot of thought went into its organization (with the inclusion of die public domain disks and die virus protection), and the freely distributable software Index is a great idea!
I want also to resolve a price discrepancy. We sent a price and product list some time ago. The prices in the catalog are based on the original information.
Since that time, we enlianced and upgraded several of our products (we're always doing that) and adjusted die prices accordingly. We then shipped an updated catalog. So, the prices in the Product Guide are the old ones, but no problem. We are more than happy to honor the old prices and ship the enhanced versions for as long as people request them! If they say they saw it in Amazing's Product Guide, they get the special price. It's the honorable tiling to do and we just wanted to let you know our policy on this one.
Congratulations on an enormous job well done!
Very' Sincerely, Julie Petersen, Graphic Services Dear AC, I would like to inform you of a few problems that I have found with some recendy released Amiga software. I offer these comments as a means of educating others about the varying quality of Amiga software.
The first (and most obnoxious) product is a desktop publishing system called ¦‘Publisher Plus” by Northeast Software Group. I purchased this product to do a local newsletter. The features described in their ads matched my needs fairly well, and the price was reasonable (about $ 70). As I found out, die actual software is VERY buggy. It is hard to work for even an hour widiout diis program displaying the almighty Gum message. In addition, a number of other aggravating bugs exist. For instance, if you choose italics as a font style (using die keyboard shortcut) and start typing, the cursor will
not move, but the text will scroll to die right, spelling your words out backwards. It is also impossible to get exclamation points in the Helvetica font even though they exist and can be seen if loaded into die notepad. It appears to me that this product has never gone through any quality control process. I challenge you to locate a copy and examine it for a while. I’m sure you will understand my concern.
Above all of their other faults, I have call ed their technical support line 5 times, only to get a recorded message. Each time I have left a message widi my phone number (and some increasingly angry remarks), ail of which seems to have been done in vain.
The other product that I would like to discuss is Deluxe Print II which was sent to me around December 1.1 had ordered (and PAID) for this product back around February '88 when a flyer was sent encouraging me to upgrade my original.
The check was cashed at dial time even diough the product came 9 mondis later.
In November, I received a letter saying diat my long-awaited program was soon to ship, but was being delayed to allow quality control to make sure tiiat everything was perfect. Well, when it finally did come, I ran die program and found it did indeed do all the wondrous things that were advertised except print.
That's right, Deluxe Print EE does not support or work with any of the 1.3 printer drivers which have been around for at least 4 months now. Since I have a NEC-CP6 24-pin printer, I find die program a bit useless. I do have an old
1. 2 driver for it, but it is extremely slow, taking about 15
minutes to print one page.
How a large company like Electronic Arts can put out a product that is outdated from day one is beyond me. I have called diem up and they say they are diinking about possibly doing a 1.3 version, but could give no assurances.
Anodier problem that I found with this program (and also with Deluxe Paint) is the limited set of fonts that can be loaded in. If you add three more fonts and load them in, the program hangs and cannot be killed. Programs like this need to be more flexible with respect to fonts.
I have also found that under 1.3, my original of Ferrari Formula One no longer works. I am not sure why, but for now, it guru’s as soon as the actual driving scenes appear.
I would appreciate you contacting these companies on my (and the .Amiga computing communities) behalf.
Just so diis letter isn’t a total downer, here’s a few tricks with 1.3. If you would like to display your path in your prompt string, but don't like the continually changing prompt size (or position) you can display your path on one line, and your prompt on another. Just incorporate die escape sequence “ esc D” into your prompt siring (in your Shell-startup file).
This sequence moves the cursor down one line to the beginning of the line. My prompt string looks like this: prompt "%N ese D$ " (continued') UPGRADE YOUR AMIGA!

Just in case you need to know, I am working on an Amiga 2000, currently running version 1.3 (although I tested Publisher Plus under 1.2 and found the same bugs) with 1 meg memory I also have a GVP SCSI controller connected to a Quantum 82 meg hard disk. I hope to hear from you soon about these software manufacturers.
Mark Steffensen Mt Prospect, LL Dear AC, I enjoyed reading Phil Saunders’ “Converting Patch Librarian Files” article in your December issue, and was gratified to see that he used my book, “The Complete DX7”, as a reference.
The problem of converting patch files from one computer to another need not, however, be nearly as involved if you remember that MIDI itself is a standard, regardless of tire device from which MIDI data originates. Rather than transferring patch data in a raw, binary format from computer to computer (in this particular case from a Mac to an Amiga) via a null modem cable, Phil may have found his task to be much easier if tire data had been transferred over a standard MIDI cable from the Mac’s MIDI interface to his Amiga's MIDI interface.
To facilitate the transfer, there’s no need to use any kind of communication program simply use die patch librarians themselves. Instruct die receiving computer to receive a full bank of patches and then tell die sending computer to transmit a full bank. Neither computer will have any idea that it is “talking” to another computer as opposed to the synth itself, since any handshaking drat is necessary (and handshaking is not used by Yamaha instruments, anyway) will be done by two librarian programs. The receiving computer will then turn to its librarian software to do all die work of converting
die incoming MIDI data to whatever format is required for disk storage.
At my facility, the Center for Electronic Music (a non-profit facility, based in New York City and open to the general public), we have PC-compadbles, several Macintoshes (Pluses, SE's, and II's), along with a number of Mega ST computers (no Amiga as yet, but we're talking with Commodore and hope to have a 2000 very soon). We’re constantly transferring patch data from one computer to another, and diis is by far the easiest, fastest, and most efficient way of accomplishing diat task.
Incidentally, we have published a number of “Compact Guides" to MIDI software for the Mac, the PC, the Atari ST, and die Commodore 64 128, and expect to be producing a book dedicated to MIDI software for die Amiga in 1989.

And even more important in the Amiga's multitasking environment, HardFrame 2000 has extremely efficient DMA circuitry to get on and off the bus in almost no time at all: 280ns to get on; 200ns to get off. And it's true, dedicated DMA, too! HardFrame 2000 autoboots and automounts directly into the AmigaDOS™ 1.3 Fast File System (old file system partitions are not needed!).
The core of any DMA SCSI interface is in its SCSI protocol chip and DMA chip. MicroBotics has chosen the new, high performance Adaptec AIC-6250 SCSI chip, capable of up to 5 megabytes per second raw transfer speed, and the Signetics 68430 DMA chip running at 12.5 megahertz. Then we added additional FIFO buffering and enabled 16-bit wide data transfers for maximum throughput. The sophisticated design of HardFrame 2000 provides for automatic SCSI arbitration, selection and reselection. The hardware supports either synchronous or asynchronous data transfer. HardFrame 2000 can function as either
the SCSI bus initiator or the target and can reside in a multiple master environment. Physically, HardFrame 2000 is optimally flexible: the compact, half-size card comes attached to a full length, plated aluminum frame. The frame has mounting holes positioned to accept standard, 3.5" SCSI hard disk units such as those manufactured by MiniScribe, Seagate, Rodime, and others (hard disk mechanisms must he supplied by the user or his dealer as a separate purchase item). Alternatively, you can cable-connect to a SCSI drive mounted in your Amiga's disk bay or in an external chassis. As many as
seven hard disks may be connected to a single HardFrame
2000. There is no size limit on each disk. HardFrame 2000
includes a 50-pin SCSI cable and header connectors for
cither 50-pin or 25-pin cable connection. Also included is
a current tap to power frame- mounted drives directly from
the slot itself. HardFrame 2000 comes complete with driver,
installation, and diagnostic software.
Available NOW! Suggested list price, S329 (hard disk not included) Frameless version: S299.00. See your Amiga Dealer.
The HardFrame 2000 photo shows the product with a MiniScribe twenty megabyte hard disk installed. Hard disks are not included in the purchase price of HardFrame. Note that if placed in the first slot, HardFrame uses only one slot even with a disk attached.

New Products and Other Neat Stuff by Mike Creeden Face-Off Springtime is coming, sports fans, and that can only mean one thing. You guessed it: the Stanley Cup playoffs.
Now you can warm up for the playoffs with the only hockey game that bears the name of the Great One: Wayne Gretzky- Hoc key, from Bethesda Soft works.
To give Wayne Gretzky Hockey the most realisitic feel possible, Bethesda called in Gretzky and a slew of other hockey pros to work with die developers producing the game. Their efforts weren't wasted. Each player acts independendy, and you never know what might happen.
Multiple player skill ratings let you race your players in 11 skill categories, including skating ability, stamina, puck control, and aggression. Options include dual game speed, multiple difficulty levels, practice time, adjustable period length, and more. You can coach the Figure One A screen from Wayne Gretzky Hockey. The ice, once smooth as silk, begins to show the wear and tear from 10 hard- skating hockey pros.
Team yourself, or let Number 99 take the helm while you watch from die stands and enjoy a hot dog.
Realism abounds here. The ice, freshly zambonied at the game's start, shows grooves of wear as the game progresses. And you'd better keep your men aggressive, because fights are bound to break out. When they do, digitized fight videos will give you a close-up view of the flailing punches while you listen to insults being spewed through busted teeth.
Those are real punches you'li be hearing. The digitized sounds are taken right from real hockey games. Instant replays let you relish that smoodi breakaway or that crushing right hook one more time.
And since no simulation would be worth its salt without the zebras, animated referees wrill keep an eye on the action. So keep it onsides and watch that stick.
The game is even endorsed by the Great One himself. So celebrate the coming of spring fhe Canadian way. Play some hockey.

M. A.S.T. Another mini peripheral has crawled out from under die
the M.A.S.T. Memory: and Storage Technology: (MA.S.T.) has
recently introduced MICROMEGS, an alternative to the Amiga 501
internal expansion RAM.
MICROMEGS features 1 megabit DRAM technology, which reduces the card size by about one half, while also reducing the length of the onboard conductors to minimize transmission line effects, and to offer greater noise protection.
The 1 megabit DRAM technology also means diat the card only requires 4 CMOS RAM chips, for significant savings in powder: MICROMEGS use 8mA in "If an Oscar were to be presented for Technical Excellence in Amiga Graphics, the winner would certainly be (the envelope, please) - The Director an exciting, unique program.. .likely to become a classic..

Artists everywhere, now hear this: This summer, Mojo
Softwarewill assemble an Art Show on Disk of pictures created
with the Mojo's Basic Art Encoder and its freely distributable
little brother. MiniCoder. Anyone who submits a 320 x 200
slide show by the July 1st deadline will have at least one of
those images included in the Art Show on Disk collection. (The
images must be freely distributable, and the disks will not be
returned). So, get those images in now, and have your work
displayed in an art show.
Using the Basic Art Encoder for those images shouldn’t prove difficult at all. It's a simple paint program that operates like any other menu-driven graphics tool, with one exception.
Instead of saving infonnation about every- pixel in IFF format, the Basic An Encoder produces an AmigaBasic routine that will recreate your picture using commands. This reduces the huge IFF file into a fairly small routine you can paste directly into your program.
The Basic Art Encoder comes with a freely distributable slide show program which lets you put hundreds of images onto a single disk. You can create a program that displays one image every five seconds for twenty minutes without ever reading off the disk. .'All the routines are in memory' once you load the slide show.
Save yourself time and frustration by using the Basic Art Encoder to construct your graphics routines. And Mojo will display the results at the Art Show on Disk.

Rare is the person who is doesn’t know they should back up their files often, Equally rare is the person who actually does it. Why? Well, backing up takes time. Backing up a drousand-line program, or a 50-page WP document, or a huge graphics image takes time, and lots of it. No one intends to let all that time go by between saves. It just happens.

ExpressCopy can perform hard disk backups and copy files from hard disk lo floppy disk at up to 1 MB per minute, or 600Kb per minute with verify of backup disks. The backup disks have die same directory structure and file attributes of the original files, and can be used normally. You can -write Normal or Fast File System-compatible disks, and collect files to be copied by DataStamp, filename pattern matching, the archive bit, or the source directory. There are options for setting die archive bit, verifying the data written to the floppy, and estimating the number of disks required for the
Create up to 4 backups at a time, or preload disks in up to 4 drives.
ExpressCopy automatically formats and verifies new' disks. Also, if a bad disk is found during die verify, you can insert a different disk and start from the beginning of that disk. There’s no need to restart the backup.
For effective multitasking, you can change ExpressCopy’s priority while it's running. If creativity strikes in the middle of a backup, halt the backup and use the drives normally. Then restart later.
ExpressCopy backup restoration uses any file copy program, your favorite directory' utility, or ExpressCopy’s owm Restore program. The program has no copy protection, and runs from Workbench or Clf. It requires at least 512K RAM and Version 1.2 or higher of AmigaDOS,’ Avoid die (hard drive) crash. Take the Express-Way.

• AO by Jon A. Bo ulle Amazing Hard Drives DRIVES ,,m
(nfaoda.ction In the beginning there was...... Techmar,
MicroForge, and Byte by Byte. A 20 MB hard drive cost SI200.
The Cadillac of the hard drives, the “Pal”, cost about S3200 without the hard drive!
These drives are no longer available except as used items. Instead, we have generic PC priced hardware. This tower priced hardware is causing a lot of confusion among new and less experienced users and potential buyers. A case in point is what happened to me.
I was trying to sell a hard drive SCSI controller for the A1000 and I got a call from a prospective buyer. As we talked about the controller, it became obvious to me that he had little or no concept of what he was doing. I’m not being derogatory, it's just that he thought all he needed was a controller and a hard drive to use it. I asked if he was going to use an OMTI or an ADPETEC card. He didn’t know' he needed one. I asked if he had the cables necessary'. He didn't know he needed those either. The net result was that I didn’t sell the C-Ltd controller. Not because he didn't want it, but
because the cost had just about doubled for him and he couldn’t afford all the equipment needed. The idea he had was dial a controller cost a couple of hundred bucks, a hard drive about S350, so for $ 550 he wrould have a hard drive.
This misconception is widely spread, especially in the Amiga world. AS co-SYSOP of one of the most popular Amiga specific BBS' in the country, I began to notice that more and more questions were being asked on the board about hard drives, problems, costs, “how comes...", etc. The problem I was faced ¦with is that old messages scroll off the message base as new messages are added and I wound up answering the same questions time after time. In frustration I began to write die answers down and posting them as a text file.
The flood of hard drive controllers on die market now' has made it more and more essential for a more comprehensive file. I began to ask friends who owned other hard drives and hard drive controllers to give me information on dieir experiences with their hardware.
This file began to grow' and grow. Thus diis series of articles began.
This series will provide basic, generic information about hard drives. As the series continues, I hope to write an article specifically for each hard drive controller on the market. 1 have contacted or will contact every manufacturer currendy selling an Amiga specific hard drive. The articles will contain the information provided to me. I will then include user information from the Amiga community. No sugar coating, no company drivel, “..just the facts ma'am, nothing but the facts...". I also hope this wall help those w'ho are considering buying an older piece of equipment that is no longer
being supported, a MicroForge or Techmar hard drive, for example. That way you will have some source for information other than what the seller told you. This information might be invaluable when you are attempting to set up your new hardware around 3
a. m. when none of your friends would especially enjoy a phone
I’ll point out the pitfalls, the traps, the possible errors in the documentation, the kind of dungs that drive you absolutely nuts when the documentation writer knows exacdy what he was talking about, but no one else does.
One of the keys to the success of this series of articles is your help. Your questions will provide the backbone of this series. As I answrer more questions, 1 will be able to compile them into a rational series for everyone. Please feel free to contact me with your questions answers on PUNK (PeopleLINK) as “Jon B” or on Amiga Doc BBS (312)351-8815- If you own what can be considered an “Exotic” setup, I particularly want to hear about it. Just remember, I don't have all die answers but I have a lot of information diat can help in a lot of instances.
There are a few' hard drive interfaces available in die PC marketplace today. In order of transfer speed they are: SCSI (up to 700k sec usually 500k sec), EDSI (300-400k sec), and ST- 506 412 - generic PC (approximately 275k sec), These speeds will vary so don't be upset if you can get faster reads and writes dian I have listed here. That's quite possible. In some cases, it will be Basic, generic information about hard drives. No sugar coating, no company drivel, “..just the facts ma’am, nothing but the facts... ”, faster since die hard drive’s access time will help determine diis transfer
We will primarily discuss the SCSI and the ST506 412 since these are the hard drive interfaces we will most likely see and use. A definition is in order. SCSI means “Small Computer Systems Interface”. Don’t be fooled by this name.
This standard is only adhered to the point that all basic commands wrork according to diis standard, not all SCSI hard drive manufacturers comply to all SCSI commands. In fact most do not. A case in point is that the SCSI bus is supposed to be a 50 pin type connector.
Apple has changed diis. Their SCSI bus connectors start out life as a 50 conductor cable, but then change to a 25 pin DB connector.

7. 5 MBITS This was done to cut down on RF (radio frequency)
interference in a home environment, because a 25 conductor
cable is less likely to cause this interference than a flat,
50 conductor cable. This SCSI bus connection is known as
variety because the Apple Mac is the most widely installed
computer that utilizes this physical format. For our purposes,
don’t worry, the majority of SCSI controllers for the Amiga
also support this DB-25 connector.
The important thing to be aware of is that for one hard drive installations, this cable change will have no bearing.
Especially if you are installing the hard drive in a 2000. It is only when you attempt to add an additional drive that this connector becomes important.
Recently, Seagate and Miniscribe have begun to manufacture hard drives with built-in SCSI controllers. The one drawback is that the imbedded adapter only controls one hard drive. The Adaptec and the Omti can control two hard drives (with the proper Tee adapters). For those of you who are fortunate enough to have more than one hard drive this is important. For die rest of us, it really doesn't matter. A drawback is that a hard drive configured this way is roughly $ 75-580 more expensive than a ST-506 412 type drive.
The following is a excerpt from UseNet authored by Thad Floryan concerning pin-outs and a brief discussion about SCSI interfaces. Thad's work was reviewed and checked by John Lo- hmeyer, chainnan of the ANSI X3t9.2 SCSI committee, who commented favorably.
The excerpt is as follows: Many systems supporting SCSI (Amiga, Mac etc.) use a DB25 at the host to save real-estate: Tije SCSI devices themselves use the "correct ’ 50-pin connectors (either Centronics 50-pin or the dual 25-pin row kind). The so-called “Mac System Cable" has a DB-25 on one end and a Centronics 50-pin on the other. SCSI interconnects are 50 wire.
At the end of this posting are the pin-outs of the DB-25 and the 50 wire (see table one SCSI pin-outs.) One thing I bate noticed (after adding over 1 GB HD and a Fujitsu WOMB tape drive to my Amiga’s SCSI bus) is that some device manufacturers take liberties with SCSI wires 20, 22. 24, 28, 30, and34. Some tie them to ground, some tie them to +5vdc and some leave them (property) unconnected.
“pseudo-SCSI". Another part of this is that usually only 25 conductors actually do anything. The other 25 are connected to ground. Most of the SCSI drives you will find available are the “pseudo-SCSI" Another caveat with multiple devices on a given bus is to be SURE that only one is supplying +5vdc on SCSIpin 26for terminator power, Some manufacturers provide jumpers to enable disable, some feed thru a diode, some feed the power out"raw”, and some do nothing.
With my system, I supplied terminator powerfrom the host adapter; and used an external terminator at the end of the bus.
From my experience, I suggest that when you’re making the cabling, pull pins 20, 22, 24, 26, 28, 30 and 34 from the connector that attaches to the embedded SCSI drive and or I translator.
I've noticed that Apple’s SCSI interconnect cables do not pass pins 20, 22, 24, 28,30 and 34 (for the reason I’ve noted above). Another observation I’d like to make is that many of the third party consumer-grade manufacturers of SCSI Hds wire their boxes incorrectly. SCSI specs mandate no more than a Iocm “stub ” off the bus, yet many Mac-type drives I’ve opened up (Justgotta see what's in there!.-) have a 2"50-wire connection joining the two Centronics connectors continuing with a 15”stub to the 50-wire connector on either an embedded SCSI drive or an Adaptec 4000A or 4070 translator. This
mis- wiring would account for the problems people have running a SCSI bus out to 20 feet. (I have no problems since I wired my system correctly, and the last device is 19' from the host adapter.)
DOS PC you probably have seen this type of drive attached to a Western Digital hard drive controller. Don't misunderstand me, this is an old hardware interface but also a good one.
It has been around a while and third party developers and OEM’s have had a chance to “de-bug” this interface, it is now possible, with this older technology, to increase the storage capacity on a given drive via R1L encoding.
But all is not sunshine with this data encoding method. It is possible to compact too much data on a surface which results in the dreaded “Read Write” error message being sent. This is self-defeating to say the least. It does no good to compact it to the point where it is unreadable. Hard drive manufacturers are well aware that their drives are being encoded this way so they are taking steps to allow for this. They began paying a lot more attention to the quality of die surfaces of the disk platters in order to accommodate this RLL encoded data, and most important, die error free Remember:
SCSI wiring is supposed to be daisy-chained.
Final note: You ’11 save yourself a lot of time (andpossibly grief) by simply buying a so-called “Mac System Cable” (50-pin Centronics to 25-pin DB25; the brand I use is Data-Spec (just as good and much less expensive than the stuff from Apple and other third party manufacturers).

7. 5 MBITS retrieval of that data. You may have noticed that
Seagate has begun labeling some of their drives with an “R”
This denotes RLL capability. This also means the surfaces on the designated drive can have data compacted and give more storage space. How much Rli. It can take is up to you and die RLL controller you might buy. For die Amiga this is not important. I am not aware of any Amiga ST-506 412 hard drive controller that directly supports RLL. For those of you seeking this data compression, you have to go to SCSI, if you can be sadsfied with die standard 17 blocks per track that MFM provides, then ST- 506 412 is for you.
Hard drive is SCSI rather than ST-506 412? As a general rule, if die hard drive requires a 50 pin connector, then it is SCSI. If it uses two connectors, a 20 pin and a 34 pin, then it is usually a ST-506 412 type drive. An advantage to SCSI is diat the SCSI host controller can handle up to seven devices daisy-chained together, while the ST-506 412 type host controller can only handle two devices.
For future expansion it is obvious that SCSI has die advantage. If you decided to add a tape backup you could, with the proper software drivers, just plug it in and run it. Then if you decided to add a CD-ROM player after that, again, all you would need to do is plug it in and use it.
Under the ST-506 412 format you would need an additional controller just for the Is it SCSI or is it...?
How can you determine whether a diird device. This SCSI expandability comes at a price, but if you look to the future it is obvious that the additional cost is minimal and worth the investment.
Any ST-506 412 can be convened to SCSI using a SCSI adapter. There are several brands on the market today. The Adaptec and the Omti adapters seem to be the converters of choice with most third part)' hard drive builders. C-Ltd previously used the Adaptec 4xxx series but has recently changed to the Omti 3527 converter. According to Ed Lippert, the Omti is a much faster controller than the Adaptec. The reason is that the OMTI controller allows an interleave of 1:1 while the Adaptec needs an interleave of at least 3:1.
Interleave is a handy way of making an older hard drive with slower access time appear faster than it would under normal conditions. It works in a relatively simple way. In a drive that has fast access times, it is possible to read data blocks sequentially, one right after another, With slower drive (access time) this cannot be done. The drive actually has to make one more complete revolution to read that next data block.
This takes time. Interleave allows the drive read head to skip blocks so it will pick up tire next data block requested by die DOS.
If you don’t understand this concept dien I’ll try to explain. Think of the track on die hard drive as a segmented caterpillar. With 1:1 interleave the segments are in die order we would expect. Data block one followed by data block two followed by data block three, etc, etc. With an interleave of 2:1 it might look more like this: data block one, data block tliree, data block two, data block four. In other words, the read head “skips’’ a block. This also is the same way interleave would work at 3:1 or 4:1 except the data block arrangement would be different. Simply pul. Interleave skips
that many data blocks before it reads the second data block. The drive spin speed hasn’t been increased in any way, data blocks have been re-arranged so die drive can read them without having to wait for another revolution of the platter.
Interleave is controlled by die OMTI or ADAPTEC cards rather dian the host controller or the Amiga. It is set up via die low level format you must do on all drives BEFORE you do die high level Amiga DOS format. If you will notice, the mountlist in your devs: directory always has the interleave factor set to 0 because AmigaDOS doesn’t have anything to do with the low level format of the drive.
What actually does RLL do? RLL compacts data on your hard drive by formatting more blocks per track than the normal MFM encoding. MFM encoding allows 17 blocks of data per track while RLL allows 26 blocks per track. A 52% increase in blocks per track gives you a corresponding increase in data storage.

4. 0 MBYTES In the MS-DOS world, RLL encoding comes in three
flavors, all allow data compaction. The three can increase
storage by 50%, 90%, or 100%. We are concerned widi the basic
50% data increase supported by the OMTI 3527 or Adaptec 4070
controller. Both diese manufacturers also support die standard
MFM encoding widi different model controllers.
A note of caution is in order here.
Manufacturers are not ones to overlook a way to make more profits. When it became obvious diat dieir drives would support RLL encoding, Seagate and Miniscribe jumped on the band wagon and began marketing RLL specific drives.
And as far as can be determined, there is no physical difference. What they did was to disable die RLL abilities of their non-specific RLL drives by a PAL in the drive controller board.
What tipped me off was this: A friend who runs a large BBS installed a Seagate ST-296 on his system about two years ago. This drive was rated at 80 MB, but by using an Adaptec 4070 controller it was able to format the drive to 120 MB with no problems. He wanted to expand hLs board so he went with what lie knew by ordering another ST-296. He figured he would then have an additional 120 MB drive for his BBS.
He had problems. The drive wouldn’t fonnat. He eventually called me since we run the same basic equipment (C-Ltd controller to an Amiga) and drought I would be able to fonnat it correcdy. He came over and we spent about 8 hours trying to solve this problem. Finally, we gave up. It just wouldn’t accept RLL formatting. I dien called a friend, Nathan Barber, who is a true hardware GURU. He then explained that a PAL chip was apparently added, thus disabling the RLL capability. The only difference in the drives is that one is about two years older than die other and the added PAL chip, Don’t diink
you can RLL encode a new non-RLL specific drive from Seagate or Miniscribe. You will probably run into the same problems we did. Currendy, we are attempting to get more information on this. If it is simply an added PAL, it should be easy to remove it and enable RLL encoding. However, it might be a bigger project than we think. Of course, this would void all warranties from the manufacturer, but would be worth it. I’ll let you know what we find.
With die new FastFileSystem introduced with WorkBench 1.3, you get an additional 5% increase in data storage.
This is due to the new way AmigaDOS actually handles blocks of data along with faster data access. The FFS (FastFileSystem) now reads and writes 512 byte blocks rather dian die 488 bytes per block under the original AmigaDOS.
ESDI Ha rd Drives ESDI (Extended Small Device Interface) is die third type of hard drive you will see available from manufacturers. If you read the fine print that accompanies the ads for these drives, you will notice the HUGE storage capacity you can get from one of them.
An example of diese capacities shows diat diey are, indeed, getting a lot out of a very small package. Consider this: a 3-5 inch half height ESDI drive with a capacity of 110 MB, a 5.25 inch half height drive widi a capacity of 383 MB, or a 5.25 inch full height hard drive widi a whopping 777 MB capacity.
How' is this done? These capacities are available because ESDI will allow the hard drive to use up to 16 heads, which means 16 surfaces are available to die drive. SCSI and ST-506 412 are limited to only eight heads or surfaces. This format (continued) Meet a team of the friendliest financial organizers you’ll ever run across.

consideration but for a less confusing listing. If you would
like to have dtat information too, I will gladly post it. Just
let me know.
Please don’t bother calling diese manufacturers thinking you will get a better price by buying direct from the factory. It just doesn’t work that way.
They all sell through distributors located in various parts of the country. Don’t think the distributors will give you a break either. They will generally quote you list price for a specific drive. The information they give you will be extremely helpful because they can give you specific product information. Above all else, they can tell you which retail dealer is carrying the hard drive you are looking for. The retail dealer is the one person in the chain that can and usually will give you the better price.
The product listings you see here might not include the hard drive you own or the one that your local dealer is selling at a great price. These lists include only the currently manufactured hard drives. The best prices in the stores are on the “close-out" models which are no longer being made. I would suggest that if you have the opportunity to get one of dtese close-out drives, do it. The quality is there, it’s just there are newer models available.
Next time I plan to bring you more information on Amiga 2000 hard drive controllers, specifically, the Supra controller with a Seagate ST-157N hard drive and a Supra controller using a MicroScience HIT-1060 with an OMTI 3527 SCSI adapter. Until then.... happy computing!

(818) 704-9500 Adding a by John P. Twardy When I upgraded my C64
to an Amiga 500,1 thought the half megabyte of memory
included would be sufficient for a long time. I brought the
optional battery-backed clock with the additional half
megabyte of memory built in, mainly for the battery-backed
clock, not for additional memory. However, in using the
A 00 to develop a new approach in investment software, I
quickly found that the 1 megabyte of memory' was actually
taxed over the limit, and that the 8 full disks I needed to
manage all of the files were getting very unruly. Disk
swapping was consuming a lot of time and effort. I decided
I needed a second disk drive, similar to my old C64 setup.
Being in the new age of computers, I figured I'd buy a hard disk for my computer. Having read many articles extolling the virtues of the hard drive, and how one could never go back to the ways of the floppy', my' interest was piqued. Since the floppy drive and the hard drive were about the same price, around S200, (at least that's what it cost to add a 20 megabyte hard drive to our office XT) I figured I would spring for the hard disk.
The basic hard drive for an IBM is the same drive for the Amiga. However, here it comes you need a hard drive case, power supply, interface card, controller card, and cables, cables, cables. They all add up to big bucks.
Trying to shortcut the packaged cost, I looked into putting together a built up system of my own.
The first choice was whether or not to put together a PC or SCSI system. I made the SCSI choice. I won’t go into all of my reasons, but the two most important ones were (a) the cost was comparable and (b) the SCSI choice seemed to offer more expansion compatibility' with the future (ie. Optical disk drives, etc.). A year ago I didn't think I'd need more than 1 meg of memory'. Now, I don’t think I’ll ever need more than one 20 meg hard drive, or maybe two? I’d better plan now for die WORM drive!
Before we start construction, we need to make one more choice: Do we want a system that uses the older style MFM data formatting or the newer RLL formatting that increases the storage density on your hard drive? If you’ve follow'ed me this far, you know I chose the RLL format. I figured by the time I got this project off die ground and working, even die latest technology' might well be on the way out.
Armed with the following, we can now start the assembly:
a. 1 Seagate ST238R 30 meg 5 1 4“ half height RLL hard drive $ 229
LYCO Computers
b. 1 Adaptec A4070 RLL controller, $ 98 Computer Surplus Store
c. 1 Hard drive case and 60 watt power supply $ 79 Wetex Int.
D. 1 Supra SCSI Host adapter S149
e. 1 50 pin jumper cable $ 12.95 DIGIKEY The total comes to $ 568,
$ 300 dollars less riian die store bought variety.You could
knock the price down even further by going for a 10 or 20 meg
drive, a single hard drive case and power supply, and possibly
even a cheaper SCSI host adapter, but look at die following
built-in value.
The hard drive case, power supply and controller can handle two hard drives. Thus, for die cost of anodier drive (approximately $ 200) you can have a two hard drive system. Also, the Supra SCSI interface has room in its case for an additional 1 to 4 meg of RAM memory', and the unit passes the buss. The system that you end up with in no way compromises your future expansion capabilities in some way's makes it too easy' to spend additional money. That’s one reason 1 like diis project: You can save up your weekly allowance and buy die parts as they go on “specials”, or you or y'our wife and
friends can each buy a part for your birthday or Christmas. It seems easier to part with the money' in small amounts than in one big $ 800 plus sum.
In addition to die items listed above, you will need the following tools: screwdriver, soldering iron, solder, two feet of 18 wire, electrical tape, voltmeter, X-ACTO knife, hacksaw, hammer and wooden chisel.
The woodworking tools make room for the Amiga and SCSI interface w'hen attached together. If you look at die Supra ads, y'ou will see diat the total width of diis combination is such that when it is installed under a typical monitor shelf, you cannot get a disk into die 3-5 drive. Thus, I cut a comer out of the middle support on my “computer work station, ” leaving side access to insert the disk. The hacksaw minimizes the amount of dust blown around the room during cutting. The hammer and chisel make a clean cut in die particai board when I went to remove the piece I cut loose with die
hacksaw'. .After we protect the computer from the mess prior to starting wmrk, and thoroughly clean the area after making die notch, we are ready to assemble the drive.
Assembling the Drive First, remove from the bottom of die hard drive case the four screws that hold die casing in place. Partially slide die casing off. Disconnect the keyed connector from the circuit board that is connected to the "power on” light. Now' remove the casing carefully.
The SCSI interface connector board requires a 5v power supply from the hard drive power supply. Using the voltmeter, verify the +5v and ground leads. Splice in the two conductor 24" section of wire and tape your connection with electrical tape. Solder the two wires to the plus and minus terminals on the connector board as indicated in the instructions provided by Supra Corp. Use an olimrneter to insure that you do not have any solder bridges.
Hard Drive Connect the cables to the connector board and controller card prior to installing the card. This prevents the card bending that occurs if you try to attach the cables after the card is installed.
Once the card is installed, it is only supported by its sides, and pressure on the card could cause damage, especially since some of the connectors are a very tight fit.
Connector pin numbers 25 and 26 on the fifty7 pin ribbon cable should not be connected, per the Supra instructions.
I used the X-ACTO knife to cut the two wires in the ribbon cable, and taped the ends to prevent possible shorts. Fold the ribbon cable to turn the fifty' pin connector over so it will match up with the proper pin configuration at the connector board and the SCSI controller. Make the folds flat to facilitate card installation.
Remove two screws securing the side card support, install the card and reinstall the side support by putting tire screws back in.
Install an RF shield between the controller card and the hard drive. I used two pieces of cardboard to sandwich four layers of aluminum foil, taped on tire edges. Make sure no metal is exposed, and tape die shield to die sides of the hard drive casing above the controller card. It helps if the shield is a litde wider tiian the drive casing it provides a snug fit and reduces the possibility' of it slipping down and contacting the controller card components.
Install the hard drive by sliding it into place and inserting die eight screws that came with the power unit. I should mention that the 34 pin cable that comes widi the disk drive does not have the proper end connectors.The components require diat the 34 conductor ribbon cable have two edge card connectors.
The cable supplied has one edge card and one pin type connector attached.
The inexpensive solution is to cut off the pin connector and install a three dollar Radio Shack edge card connector.
Connect the two cables and power supply to die hard drive. Check the pin numbers to make sure that all connections are made to die proper terminals.
The power supply connector is keyed.
Inspect die installation carefully. Make sure all connectors are fully seated, power supplies are connected properly, and that no wires or cables are touching any of the power supply components, especially the heat producing ones (see figure diree).
I taped the bottom side of die connector board with electrical tape to prevent It from shorting out on the casing assembly because the cable that runs to the SCSI interface may jiggle and cause the connector board to move inside die casing. Install the blank front piece if you are only installing one hard drive at this time. Slide die casing partially on, connect the “power on” indicating light cable, then slide it on the rest of the way being careful not to disturb the wires, cables and board.
Install die four screws on die bottom of the casing.
Remove the plastic cover from the left side of the Amiga and slide the SCSI interface connector onto the edge card in die Amiga. Connect the cable from the connector board to the SCSI interface.
Connect the power cord to the hard drive casing.
You are now ready to [rower up the system. The instructions state that in your power sequence, the hard drive should be turned on first and off last.
Also, allow die drive 15 to 30 seconds to come up to speed before trying to access it. Turn on the power to all of your components and run the Supra Formatting routine provided with the SCSI interface. They didn’t have a listing for the ST23S so I used die Miniscribe 8438 listing which set all of the parameters I needed automatically. The software provided widi the SCSI interface is very good, as is die documentation. Among die utilities provided is Climate, which is very useful for installing software on the hard drive. The Supra formatting software allows for five hard disk partitions, bur
CLImate can only handle four.
The unit formatted flawlessly.
Actually die hard disk did have a bad section that the software formatted around. It’s a good idea to check that the formatting picks up the same bad sectors diat are identified in die test data that comes with the drive.
I loaded my WordPerfect software onto the hard disk and finished writing the article using it. The setup is one nice piece of hardware.
One final dp: Put a piece of tape over die unused host connector port on the back of the hard drive case. This prevents the cooling air from “short circuiting”, or bypassing, die hard drive itself.
I would like to thank all of the people I talked with at Supra Corp., Lyco Computers, and Sunnyvale Memories for their help and information, Good luck!!

Hard Drive Reviews TheM AX by Donald W. Morgan To begin, let’s
say your Amiga 1000 sports two 32 megabyte hard drives. The
drives have been in operation for approximately five months,
and were built using the Max kit from Palomax Inc. of Hatboro,
The kit supplies no hardware, so you must purchase all the parts required to build and install the drives. The Palomax ad states you can build a 16 megabyte system for S400 using a rebuilt drive. 1 would say you can build a 32 megabyte system with a new drive for S525, or a 65 megabyte system for S660.
To complete the Max kit you should be able to solder or wire wrap, as well as have a little mechanical ability-. It's a start-from-scratch project, but not too difficult. And you can buy the parts you need in stages.
First, we'll look at die items you'll need to attach a hard drive to your Amiga. In the case of the model 2000, a case or power supply will not be needed. Everything else is essentially the same for all models.
You can build a 32 megabyte system with a new drive for about S525, ora 65 megabyte system for about $ 660.
You will need:
1. Max kit (purchased item)
2. Hard drive controller (purchased item)
3. Host adapter (build-from-scratch item)
4. Power supply (purchased item)
5. Hard drive (purchased item)
6. Case for interface (controller & host adapter)
7. Case for hard drive (see article) The aluminum case holds the
parts providing the interface between your Amiga and die hard
drive(s). This includes the Amiga 86-pin expansion bus
connector, the host adapter board, the IBM-type 62 connector
the controller plugs into and, of course, the controller
board. These parts can be assembled in a 7” x 9" x 2" aluminum
box available at Radio Shack or other electronic supply
For my setup, I made a custom case with two 7" x 1" aluminum covers and two 1" wide by 1 4" thick aluminum bars which provide the spacing and support of the covers. The OMTI 5527a controller I used supports two drives, but the kit provides for two controllers so you can support four drives. For two controllers, you will need the thicker 2" case or box.
If the Amiga bus were IBM- compatible, we could wire die 86-pin Amiga edge card connector directly to the 62-pin controller connector. The small host adapter board intercepts the address lines and converts them before they go to the controller connector.
Looking at Figure one for the model 1000 and Figure two for the model 500, you can see that everything is constructed on the cover of the box.
After assembly, screw the cover to the box and plug die completed interface into the Amiga expansion port. Except for placement of die host adapter board and the Amiga S6-pin expansion connector, the two models are the same, The Max kit provides all the mechanical sketches and dimensions for the diree models. 1 designed my host adapter a little differently, however. I feel my version is closer and more direct but, if you buy the kit, look at both and make up your own mind. I sent my suggestions to Palomax for their evaluation.
The model 2000 is built on a fiberglass board so it can be plugged into one of the expansion slots. The controller and host adapter are both attached to this board. Dimensions and wiring are provided for both Zorro I and Zorro II boards.
Getting to Work The mechanical ability I mentioned earlier will be needed to make a slot in the cover for the Amiga 86-pin edge card connector used for the 500 and 1000 models. First, scribe a center line using die dimension lor either the model 500 or 1000 and scribe or mark the ends of [lie slot. On the model 1000, lay out the connector slot so it won’t block the 2nd joystick port.
Hard Drive Construction Kit Center punch about 3 8" apart along the center line and drill out die holes. A small round file will clean out die metal overlap between holes and a flat file will smooth out the slot. It’s not as difficult as it sounds, since the aluminum is so easy to file. Try fitting the connector as you go so the slot doesn’t become oversized. Once the connector fits in the slot, mark the two mounting holes, drill them, then mount the expansion connector.
Building the Adaptor Board You are now ready to build the host adapter board, it’s made on a piece of perf board with .100" x .100" hole spacing. These boards are low cost and readily available at Radio Shack or other electronic supply stores.
Figure one gives die dimensions I used for my host adapter board. The Palomax version uses a larger perf board mounted behind die controller card. The host components are 3 I.C.’s, I.C. sockets, 1 transistor, 5 resistors, and two diodes (four diodes if you are mounting two controllers). These parts should cost under 510.
Use sockets widi wire wrap pins for the I.C.’s. For the other components, use push-in wire wrap posts. Radio Shack sells diese push-in posts (20 posts for 79 cents ) as part number 276-1987.
Three posts are used for 3 for die +5, +12, and ground from the power supply.
I mounted the host adapter board widi the components facing down towards the cover, and filed the mounting spacers so that when inserted, I.C.'s just touch the metal cover. This prevents any I.C. from coming loose and keeps the pins facing you for easy access. You can use a screw and diree nuts on each side. One nut will hold the screw to the cover, the other two will be placed on each side of the board. Turn the bottom nut to get die top of the I.C.'s to just touch the cover. Use the other as a jam nut to lock it into place. See Figure three.
The controller card has its own mounting holes so I saw no reason to provide mounung for the 62-pin connector, The controller card is also mounted widi eidier standoffs, spacers, or screws to the cover.
I wire wrapped to the Amiga 86- pin connector and host adapter board, but soldered to die controller 62-pin connector. Position die 62-pin controller connector about 1 2" up from the Amiga connector with die solder pins facing up.
You can now wire all three together.
When wired, the controller connector can be turned 90 degrees and pushed onto die controller card. You can see that most of the time involved in constructing die Max project is for wiring these three parts.
The Components I purchased my OMTI 5527 a RLL controller from L.S.I. marketing for $ 68. I chose diis model after reading test results published in a previous magazine article on Amiga hard drives.
The power supply I bought was a TimeLine 188 Watt switching supply which cost S25. It supplies 20 amps at +5 volts, and 4 amps at +12 volts. I didn’t need anywhere near 20 amps for the 5 volts, but the price was right. The host adapter uses about .02 amps at +5 volts.
The controller uses 0.5 amps at +5 volts, and 0.1 amp at +12 volts. Most half height 3.5" drives use about 1 amp at +5 and 1 amp at +12 volts. My supply had three 4-pin amp connectors. I mounted the supply on the backboard of my computer table, extending one connector to the interface box and another to die drives.
The power supply should have at least two amps per drive for die surge of the starting current in the drive motors.
Check die specs of die power supply to be sure it will stand up to die starting current. There are surplus IBM-type supplies available designed for just this purpose.
The controller card has two secs of 20 connector pins and one set of 34 pins.
For a one-drive system, you’ll need one 20-pin and one 34-pin ribbon cable which connect the controller to the drive.
I filed a small 1 16" step at the top, in line with the two sets of pins. This is where die ribbon cables will exit die interface box, so I also put tape over the step to prevent the ribbon cables from getting cut. For two drives you need anodier 20-pin ribbon cable. The 34-pin cable is daisy-chained to both drives.
These cables are usually supplied with the drives.
I purchased my drives from Computer Products Corp. They list a 32 megabyte RLL-type far $ 225 as an AT Kit.
It's a model 8438 miniscribe 3-5 “ half height widi 65 msec, average access time. If you can afford a larger capacity drive, look for die Seagate ST277R, which is a 65 megabyte RLL drive with 40 msec, average access time for $ 389. It bodiers me to see ads in which a 30 meg drive is almost 50 percent higher in price dian a 20 meg drive.
If you purchase an RLL-type controller, be sure your drive is RLL- compatible. The Palomax documentation lists a variety of drives and their compatibility.
The documentation also shows a way to pass the bus dirough if you need it. After wiring, die top and bottom rows of pins of die Amiga connector are benr closer together so a section of board with fingers can be soldered to die individual pins of both rows.
(continued) The +5, +12, and ground leads were soldered to three push-in pins inserted into the host adapter board.
These wires were terminated with an amp 4-pin connector to mate with one of the short cables on tire power supply.
Another similar cable was run from the second power supply cable to tire connector on the drives. I had to branch out the end by the drives to feed power to both drives. With one drive, you won’t have to do this.
Palomax shows an optical isolated relay to supply power to the drives. I have a power control center my monitor sits on. It has surge and spike suppression, so I didn't use die relay. It's just another item to purchase, mount, and wire. After five months of fairly heavy use, my system works fine without it.
Testing the Drives Now' that the hardware and w'iring are complete, you can get on widr die software to set up your drive(s). The disk supplied with your kit provides all the programs to test, configure, add drivers, do die moundist and assign alternate tracks to any bad tracks on your drive.
It’s almost impossible to make a drive holding 20 million or more bytes without any tiny imperfecdons, it’s like drop outs on videotape. But, unlike videotape, you don't want your important data on a track with drop outs.
Your controller is fooled into thinking there are two less cylinders than diere are. Tracks within die cylinders are reserved as alternates and assigned to die bad tracks.
Palomax does a nice job of stepping you through the software needed to set up your driveCs). You start by making a duplicate Workbench disk and deleting the utilities so there are about 100 blocks free. This freed space is where you copy die needed files from die Palomax disk to die duplicate disk.
The Tesdid2.0 program has a menu of 22 items for easy selection of the test parameters. Most give an on-screen indication of error status. The defaults are selected with a press of the RETURN key. Menu item 14 assigns alternate tracks for any bad tracks on your disk.
Your drive will come widi a test tag showing these tracks, The HDParams and moundist programs are in text widi sample parameters. Simply backspace and type in the correct figures for your drive specifications. Ask for the specification sheet when you order your drive, I didn’t receive one and had to call Palamax for help.
Technical help is available from Palamax from 6 to 9 pm (ES'lO five evenings a week and most of Saturday. I got through on the first tiy. I was stepped through each parameter as I wrote the figures next to the sample on the documentation page.

The software is set up so when you finish entering or changing die data, a simple key stroke writes the data to the controller or appropriate directory. It seems to go very fast even diough I was a littie apprehensive widi so much money invested in something I never tried before. Except for not receiving the spec sheet with my drive, everything else worked fine.
Just in case Once your system recognizes die hard drive and is formatted, you can think about putting it in a case. I made my case out of wood. Wood? Yes, Wood.
The drive is completely encased in a metal housing so die only items that can cause any interference are die PC board mounted directly under the drive and your switching power supply if it’s not mounted in a metal enclosure.
During testing, I had die first drive sitting on top of the Amiga 1000 next to the external floppy. My hi-fi receiver, two VCR’s, and TV are only two feet away. I found no signs of interference or disk-operating problems widi diem running. If you don’t feel good about a wooden case, you can line the inside of the case with foil or thin sheet metal.
By using wood, I could make die case fit the length from die external floppy to die left edge of die Amiga.
Model 500 owners need not be concerned with this spacing. Model 2000 owners don’t need a case.

With the program disk in the floppy drive, open its window' and drag the icons from the program disk window' to your Empty window'. When you finish copying all the files, select Rename and change Duplicate of Empty to Dpaint or whatever disk you are trying to port to the hard drive WorkBench.
Commercial floppies have some files duplicated on each floppy that you need only once on tire hard drive.
There are seven main files on die Max disk. The Devs directory contains the HDParams, Moundist, and hd.device files.The HDParams is an ASCII file that holds the parameters for configuring the hard disk(s) for the controller and HDParams 1 for the optional second controller. The Moundist is also an ASCII file for mounting the drives.Hd.device is the driver code for the first controller, and hdl.device for the optional second controller.
The “s” directory' has 1,2, and 4 drive sample startup-sequence files which you can start witli or add according to your own requirements. The “c" directory contains the HDConflg, testhd, and backup files. The HDConflg file uses data from die HDParams file to configure the hd.device driverts). The testhd file contains all the programs for testing, formatting, and assigning alternate tracks.
The backup file is just that, a backup program for your hal'd drives. It has options for listing files only during backup or file size and space available on the disk. There are other options for incremental backup with only files modified or created since last backup, and continuous backup from last stop point.
Two 32 nteg drives?
This brings me to die point of why I opted for two 32 megabyte drives.
What could be easier for backup than typing “Copy DHO: DH1: all", and no shuffling of floppies? I couldn't buy a tape backup system for anywhere near the added $ 225 for the second drive.
Another advantage of two drives is the regrouping of fragmented files. If you just saved your programs without deleting or modifying diem, all your files would load fairly quickly. This doesn't happen in die real life of any' drive.
When y'ou delete a file and later save anodier program, it won’t fit exactly into the space die deleted file occupied. If the new file is smaller, you will have some free blocks between files. If the newr file is larger, it will occupy die just-freed space and it more. This space may be in another area many blocks or tracks away from the first part.
To load die new' saved file, the first part will be loaded in one block after another. The heads will have to move to the other tracks to read in the rest of the file. This scattering worsens as more files are deleted or modified and the disk becomes full.
DiskCopy will copy a clone of die original (except for dare code), but Copy will copy each file, one at a time. It will take time finding all the scattered blocks and tracks, but they will be reassembled in a continuous string on the copy. Widi two hard drives and no floppies to shuffle around, it is easy to copy from DHO: to Dhl: to reconstruct the files. If you like die original on DHO:, you can now use DiskCopy to put the restructured files back and still have a duplicate backup on DH1:. Of course, you could do the same with a 65 megabyte drive partitioned as two equal drives. The Max
documentation show's samples for partitioning your drives.
One of the first questions that comes up on any hard drive is speed. 1 am currently an unemployed electronic technician, so I have no other drives to compare. 1 looked over a test (published in AC V3.10), of five hard drive interfaces for the Amiga 2000, using the new
1. 3 version with the fast file system.
One test examined die time it took to load a video page of 704 x 480 x l6 colors in Deluxe Paint II. Most took from 4.5 to 5.6 seconds, exception for die Amiga 2090a which took 53.66 seconds, (there were some problems with Dpaint and the 2090a.) I clocked loading a full page of 640 x 680 x 16 colors at 5 seconds (my electronic timer is only in seconds), with the 2.0 version of the Max sofiware. I have die new' Max
3. 0 driver software but am still waiting for my order for the

With a complete backup on one drive, 1 can format for the FFS, then copy my fries over from the backup while 1 relax and watch TV. For one drive, I recommend setting it up as wo partitions, using one partition for backup until you need the added space.
Compatibility As for compatibility , 1 can only vouch for the components I am using.
My system has the Kicks tart Eliminator from CMI and the Insider 1 meg memory expansion from Michigan Software. 1 use Addmem in my startup-sequence to reclaim the 256K in the protected write control store area for the KickSrart disk.
I have a four-way parallel switch box for a Toshiba P321SL printer. Canon PJ1080a color ink jet printer, Perfect Sound audio digitizer, and Digi-View video digitizer. After 5 months of operation, I have found no problems using the drives with any of my peripherals. I did crash my first drive trying to port some of my copy-protected software to the hard drive. Deluxe Paint was easy to transfer to tire hard drive, but Deluxe Print crashed it. Deluxe Paint II should fix this.
Another advantage to building the Max kit is the ability to upgrade whenever you want. The controller will handle two drives, so you can start with one drive and expand to two later on. Adding a second controller will give you the capability of four drives. (Imagine having four 65 meg drives under the Amiga hood.) Even if you purchase one drive, set up the software for the second. This will make it easy to add another later on if you change your mind.
The Max kit does not auto- configure, but it does have a fixed base address of F7FFE0 which, according to Palomax, is Commodore’s production test diagnostic area. Since this address is decoded for you, I don’t see any disadvantage to Max not being auto- configuring.
Besides its speed and capacity, I find die biggest advantage of a hard drive is having a full WorkBench screen with all my programs and utilities just a double dick away. It also eliminates the chore of preparing data disks and flipping through a stack of floppies to find that needed program. On the other side of the coin, you must get organized and set up your directories and subdirectories right from the beginning or you'll wind up with a large string of jumbled programs.
When the Amiga was designed, developers thought about tomorrow but not the day after. The release of KickSrart
1. 3 will bring the possibility of auto booting. Software houses
are starting to take hard drives into account in their new
programs. Things are looking up. I feel tire minimum
configuration for an .Amiga should be at least a 30 megabyte
hard drive and 2 meg of RAM. With tire floppy used for porting
newly acquired programs to tire hard drive and playing games.
Once you have a hard drive on your system you can shift out of low gear and get into the fast lane.
By John Steiner Bug Bytes The Bugs & Upgrades Column One of my greatest interests is desktop publishing, I have used the Amiga as a desktop publishing tool since its early days, and have used bodi IBM compatibles and the Macintosh as well.
Recently, I was appointed chair of tire DEPOT (Desktop & Electronic Publishers Online Terminal), a desktop publisher's support group on Peopielink, For years, I have kept watch on die slow progress of the Amiga as a desktop- publishing tool, so I was interested to find that PageStream, from Soft-Logik Publishing, has finally been released. 1 use the term finally because it has been over a year since I first saw advertising for die program.
Judging from information I have seen regarding die program, and from my own limited experience, PageStream appears to have several major bugs. I have listed them here along with a few workarounds, and some tilings to avoid, lest you enjoy frequent visits to the Guru.
Before getting down to the bug list, which I find amazingly large for a commercial release, I would like to comment that, aldiough there may be a negative tone to this report, users who have reported diese bugs are almost universally tempering their negative comments with glowing praise for the power and desktop publishing features of this program.
But it appears the program might not have been ready to be delivered.
Commercial software should never routinely gum die computer. And from die reports I have received, there are several things diat can bring on die Gum.
The following bugs have been reported by at least two different individuals. There were many more bugs reported but, as I was not able to verify them before deadline, I gave the program the benefit of the doubt and attributed these difficulties to new user errors. I have obtained a copy of the program and verified many of diese details for myself. In tile meantime, the workarounds Listed here will hopefully save PageStream users many hours of lost work.
Several users have reported, and I verified, that rulers leave ghost "tic” marks on the X and Y axis as various actions occur. This makes it confusing to determine where the cursor is. To work around this problem, go to die View menu and choose the same function that was already checked. This causes the program to redraw die screen, which will remove the invalid ruler marks. You can also remove these invalid marks by clicking on the rulers themselves.
Several users reported problems with the variable zoom tool. If you click the zoom tool too quickly, you will be off to see the Guru. A couple of users reported that if you press and hold die mouse button, then drag die mouse slowly, the zoom works properly.
Other users said even this didn’t help, and trying to use die zoom tool was never successful. In the short time I have played with the program, I couldn't get die zoom tool to crash. But I have a 3 MB computer , so it is possible die crash occurs when zoom calculations run a machine out of memory.
The program appears to grab at least 10K of chip memory every time it is run, which it does not release when the program is finished. The only way to get die 10K of RAM back is to reboot die computer. This is not a major problem if you reboot on floppy every time you run a different application.
Users with hard disks, who expect to go back and forth between applications, should keep PageStream running in the background and use multitasking if they have enough memory.
(continued) The supplemental dictionary has a problem with the Add Word function.
According to several users, if you try7 to add a word to the dictionary, you will make an unscheduled trip to the Guru.
The only workaround to this bug is not to click on the Add gadget. I verified this bug myself.
When rotating or sizing an object, make sure die object remains entirely on die working page. Should you let objects fall off the edge of the page, unusual tilings may occur.
If you interrupt the printer, you may be off to see the Guru. I would also recommend that you save your document before doing any printing. In fact, judging from comments by PageStream users, save your document often just to be on the safe side.
At Least one of die disk requesters with a slider gadget would not let you slide it back to die top again once it had been slid all die way down to die bottom. However, the up arrow works to bring the slider back up again.
Judging by the quandty and severity of diese bugs, I am not impressed with SoftLogic's quality control.
Hopefully it will not be long before they have a much smoother release ready to be put to productive use. If Professional Page hasn’t improved their dot-matrix output by that time, I will be changing desktop publishing programs. Until dien, 1 plan to wait and see what happens.

P. O. Box 290071 St. Louis, MO 63129 I have been using Click DOS,
a shareware disk utility. After using it extensively, I
decided to send them my $ 15.00 shareware fee (which was
certainly reasonable). Gary Yates, author of the program,
graciously shipped me the latest version, numbered 2,06., and
also warned me of a bug in the previous
2. 04 version. It is a particularly nasty bug so, if you are
using version 2.04, you might want to get an upgrade.
The Move command did not work properly. It did not bother me too much in that, after copying the files to the destination directory, it would not delete them from the source directory. This did not seem to be a major problem to me untill Mr. Yates reported that if the copy failed for whatever reason, the source files were deleted! Flow fortunate I was to have never had the copy fail.
According to a newsletter published by Oxxi, Inc., if you are a Maxiplan version 1.8 or 1.9 user, and have problems with garbage on tire screen, see if you are using FastFonts, which automatically executes in most 1.3 startup-sequences. According to the notice, “It seems that starting somewhere in the various releases of MaxiPlan 1.8, it ceased to get along well with FastFonts.
We are not sure why, except that it contains some code which performs the same functions." If FastFonts automatically executes in your startup-sequence, you should remove it until a bug fix or patch to MaxiPlan is released.

Election Ca*aip Soes your spouse vafit $ 1 there?
Enter an x ii Yes by Kim Schaffer Waiting for die last minute to get your taxes done this year? If you're like me, you need something to make that yearly duty a Little more bearable. So how about a program to make sure you don’t transpose the numbers from your calculator to your Schedule A? Tax Break has a lot of checking and double checking built-in, so you can rest a little easier widi the calculations, and concentrate instead on getting all those deductions.
Tax Break can definitely speed up tax filing, especially if you get conned into doing taxes for Aunt Lou, or Cousin Betty Sue. It can also provide relief that spouse who fears adding all those big numbers on that little scrap of paper, then losing the sum before you get a chance to copy it down. If you have the memory (2MB), and die patience, Tax Break can do up to eight Federal tax returns at the same time. That's way past my limit, but maybe it’s just enough for the “power” tax preparer.
Not quite as shiny as a Lamborghini at showtime, this program still has a lot of polish. Although the screen comes up a little slow, but sooner or later it's there on your screen in living color: your 1040 worksheet. (OK, so tax forms may not be something you consider to be terribly exciting.) Tax time still makes the heart flutter, and it helps to have a program that’s not just a backyard hack.
The program starts up widi the input on the label area of the 1040. Here I thought they had things backwards.
While it makes sense to start from the beginning, after reading die manual, one is inclined to do differently. Start off with the W-2 worksheet instead, as tire manual suggests. It’s laid out, just wailing for you to use it. The keyboard shortcut to the W-2 worksheet is Amiga 1 (die shortcut to thel040 is Amiga 2).
The worksheet even tells you what box number of your W-2 to look to for the input. Tax Break can also handle multiple W-2’s, up to four per person.
So, aldiough I didn't particularly like the order Tax Break started with, that didn't make me like the program any less because you can fill out the forms in any order you please, jumping around and even overriding die links.
Tax Break provides lots of help through a status line, the use of zeros, and the old double clicking for those connections to odier worksheets. The status line displays an asterisk whenever there are IRS tax preparation instrucdons available for that line. When you get to a line you don't understand, just push the Help key, and the instructions for that line are displayed. When you have read enough, hit the “escape” key, and you're back in business.
The status line also includes informadon such as where to look for inputs and what worksheets, forms, or schedules support that line. Any line that uses other lines will have a number in it, even if it is just zero. You can also see the equation for those cells by using the F8 key.
The last but perhaps most helpful tip is that when you double click the cells which use another sheet, Tax Break will load that sheet for you and show you where it needs the information to fill that line. How do you know if the cell uses another sheet? Read the status line!
These are all tricks that would probably I Figure One Although the screen comes up a little slow, but sooner or later it’s there on your screen in living color: your 1040 worksheet. Exciting!
Take you a while to pick up on unless you read the manual or, better yet, this article.
The Tax Break Program The program consists of over twenty-five schedules, forms, and worksheets that are linked together so you never need to manually copy anything from one line to another . The program is also organized so you can keep your eye on Uiat “bottom line": it recalculates every time you go from one form to another, to give you the present tax situation, and how much it has changed from last time. You can also force a recalculation at any time, to allow for “what ifs". There’s even a summary worksheet to give you the major calculations.
After you become familiar with the program and are satisfied that it really does look good, but you want a little extra speed, you can dump the glitz and (continued) Suaaiary ol Tax Return Slats Figure Two (left) Tax Break offers a summary worksheetso you can keep your eye on that “bottom line" Figure Tijree (tight) Following IRSforms, ptintouts are quickly and easily produced.

¦¦¦ ¦ still keep a very powerful tool. The interface is everything you would expect from an Amiga program: help menus to get you going, mnemonic short cuts once you get used to the program, and even a few gadgets for some of the more useful functions right up front. In fact, by the end of the tax preparation, you will probably know die ins and outs of the commands so well, you will want to attempt different approaches, do someone else’s taxes, or just forget taxes completely until next year.
Tax Break is well organized. Still, you need to read the manual to find the method and the tricks that make it a powerful tool. The manual is much better reading than the 1040 instruction booklet, although it could be a little better organized. The manual does not try to substitute itself for the tax instruction booklet, concentrating instead on familiarizing the user with the program.
Oxxi has included die tax preparation instructions, and the Price Waterhouse Personal Tax Advisor paperback to help you get organized for the job. Tax preparation is confusing, and I haven't seen anyone make it more comprehensible dian Tax Break.
Loopholes Did 1 find any shortcomings in this program? What self-respecting reviewer wouldn't find some “bugs" or “features" (depending on what side of the fence you are on) to report. Yes, 1 found a few, but most were nitpicks. Overall, die program seems to be a mature piece of software. That makes sense, since die people at Oxxi told me Tax Break had been on the market in Canada for a couple of years now.
The biggest shortcoming I found was the lack of a worksheet for personal interest. To be fair, the IRS doesn’t include one either, but I had to call up my spreadsheet program in die background to document my numbers, and then copy die total back to Tax Break.
Also, while the calculator will insert die actual total when you use the F4 key, it will round off to die nearest dollar if you use the mouse. And loading a file, such as data for a spouse, always requires clearing all die memory. Still, die program hasn’t bombed out on me yet, and there are not many programs I can say diat about.
The program is a little hard on the memory, but there are a lot of different tricks to allow you to do some multitasking, even on 512K machines. The program can also use the Workbench screen if you need to save memory. In fact, the program seems to be able to switch back and forth between screens automatically, depending on the memory situation. Also, as mentioned before, you can choose not to load background pictures, which die program doesn't really need.
Printing What about diose printouts? The IRS requires a graphic type output for die 1040 form and, again, Tax Break comes through (although not quite unscathed). I tried two different printers, a 24 pin Toshiba and an HP Laserjet. The manual and an addendum left little doubt what printer settings should be used to obtain the best output. Even with the Workbench 1.3 drivers, printing the final 1040 worksheet was painfully slow, especially on die HP Laserjet.
I was also surprised that die dot matrix printer output seemed faster, cleaner, and produced a better looking image. The Laserjet output was higher resolution, but looked as diough it had been through a fax machine. The dot matrix seemed a litde smoodier, and it was my final choice for sending to the IRS. The rest of the printouts were in Standard text format, following die IRS forms, and were quickly and easily produced.
Once you've finished printing all your forms and have mailed in your '88 taxes to get that big, juicy refund check, you're ready for the next step estimating your 1989 taxes. Tax Break does its best to help you here also. In die first menu, sitting right above die “Quit”, is die “Open a 1989 Tax Planning Return" option. This changes die program to allow for changes known for the 1989 return. It also includes an “inflation factor", which can be useful if you expect a “inflation” of income and expenditures. Note if only it would tell me how to fill out a W-4, I'd be in business!
Updates Oh well, that brings me to the final topic I wanted to mention the future of Tax Break. I think this program is here to stay, and evidently so does Oxxi. One of the first questions I asked about the program was, “Do 1 have to pay the full price every year?" If this was the case, I didn’t diink it would be worth it.
However, the answer was a resounding “future versions will be considered upgrades, and will be available to registered owners for the usual update fee, presently $ 29.95 + $ 4 shipping." This made it very attractive indeed.
In addition, the manual states “1989 Tax Break will incorporate even more forms, an even more user- friendly interface, and will integrate with tax returns for several of the highly populated states." So, if you’ve been good, you probably deserve a Tax Break.

Big Apple!
Amazing Show Reports AmiEXPO New York, March '89 1989! The Amiga opened on Broadway March 3 to 5 and, while reviews were mixed, the box office numbers could not be ignored.
Over three days, more than 11,800 poured into the second AmiEXPO NY , filling the corridors of the Marriot Marquis in Times Square with a new breed of Amiga folk.
Many of the attendees were certainly recognizable from previous shows. However, vendors did notice some significant changes in die attendees. AmiEXPO officials had targeLted college campuses, as well as, the professional video community, widi a substantial direct mail effort, and the crowd reflected this.
Professors and grad students stood elbow to elbow with directors, cameramen, and more dian sixty members of die world press. Here’s what diev saw.
NcwTek showed off Digi-Paint 3, a completely new version of the Amiga’s first HAM paint program. Digi-Paint 3 includes full Amiga font support widi anti-aliasing of text, an extended set of drawing tools with resizable built-in brushes, and user-controllable 3D texture mapping. You can now control the amount of brush warping, die “warping point” of the brush, and die brush transparency.
Digi-Paint 3’s interface has been completely redesigned by noted Amiga artist Jim Sachs, New display features include autoscrolling bitmaps up to 1024 by 1000 pixels, user-definable overscan, and changing screen resolutions on-the- fly.
Other program features include new drawing modes, an improved magnify mode, a larger palette area, unlimited brush resizing with antialiasing, brush rotation, and range painting. Written in 100% assembly code, Digi-Paint 3 has a complete set of keyboard shortcuts.
The new version is extremely fast. You can navigate between the various drawing modes more easily than before, load fonts from any disk without assigns, and upgrade from Digi-Paint 1 for $ 29.95, or from other paint programs for $ 44.95. Toast in the summer?
NewTek also demonstrated the latest version of die Toaster, now promised for summer release. The Toaster will reportedly carry a $ 1599 price tag. Allen Hastings of Rush Hour fame showed a videotape of work he’s been doing with his new “fast non-ray-tracing Tenderer with lots of advanced texture options and special effects.” He would not commit to a release date on die new program. However, others said the (Top left) Attendees enjoy new public domain Star Trek game.

Program was at the same stage Videoscape was at when Alien turned it over to Aegis to finish off. Look for it from NewTek in the fall.
Byte by Byte announced a stripped-down, nonray-tracing version of Sculpt 4D called Sculpt Animate Jr.
Priced around Si50 and geared to the A5Q0 market, the program will use and produce files compatible with its parent. The company also released a “3D Cookbook” videotape, a visual introduction and tutorial with ¦‘powerful, time-saving recipes for creating complex objects and animations."
Over at Impulse’s booth, Stan Kalisher demonstrated Turbo Silver SV, a version of the ray-tracer that produces images viewable with 3D glasses (You can use either Haitex or Sega glasses plugged into a new Impulse-built interface box).
Lnpulse’s VD-1 frame buffer grabber was also on display. This device takes any signal from broadcast, camera, or VCR and instandy grabs the image in 24 bitpianes, then sends it to the Amiga to be turned into Ham, or 32 colors in full overscan and interlace if required. Units are shipping slowly at $ 1000.
Genlocks There were several genlocks at the show. Communication Specialties showed their Gen One unit with S- VHS-compatible output signals and clean video pass- through. VidTech's Scanlock is the first to allow both input and output of S-VHS. Magni was represented at die Amicore booth, where the Canon still video system was incorporated into a full-fledged post-production video environment.
R & DL Productions announced the release of Lightbox, a new professional animation tool which allorvs you to animate cartoons with the control of a conventional light box and peg system plus the advantages of a computer paint program. Lightbox displays drawings which appear before and after die drawing currendy being worked on.
All in-betweens are hand-drawn for full control of expression of character and illusion of life. The drawings can be worked on at any time, and stepped-through frame by frame or viewed at true speed by pressing the “flip" key. Several products that allow7 diis technique have been announced, but Lightbox is here today, and works well with R & DL’s AproDraw Graphics Tablet.
Maurice St. Sauveur was showing his SMPTE Exorciser Frame-by-Frame controller system at the Alchemedia booth. The SMPTE can perform continuous single-frame stores of up to 1000 pictures per edit list, and comes with a proprietary software-based time-code generator allowing you to use the Amiga for both audio and video striping. The wide-band, bi-directional hardware reader controller reads time code and interfaces the Amiga with VCR editing decks including the JVC 8000 series 3 4 inch, JVC 810 S-VHS, Panasonic 7500-A S-VHS, and all one-inch machines. The system will begin shipping in May and
will cost significantly less than currently available alternatives.
Elan Design has a new presentation manager program called The Performer, which puts the power to display graphics and animations of different formats literally at your fingertips. You can load and view files from all major paint, 2D, and 3D packages, sequence for programmed playback, or access any imagery directly by pressing its key. The program supports ANIM, RIFF, MAM, arid RGB formats, and is programmed in 100% assembly language to facilitate multi-tasking and mem- ory-management. The output can be sent in real time to videotape, or you can separate and recombine animations into
different orders, resolutions, and animation formats.
Progressive Peripherals & Software showed FrameGrabber 256, a real-time, 8-bit video digitizer that captures interlaced, 256-shade monochromic images in 1 30dt of a second. The product includes extensive acquisition display software by Justin McCormick of PIXniate fame, and has a Delta mode for real-time image comparisons. PP&S also previewed the EXP-8000+ 8 megabyte internal expansion board for the A500, which also provides tire option of adding a 68010 processor and user-adjustable 12.5 or 24 Mhz math coprocessor. The Vault, an external hard drive for tire 500 and 1000, comes in
configurations ranging from 20 to 120 megs, die 20 meg version with controller, software and cables retailing for $ 599.95. The long-awaited Baud Bandit terminal software is ready for May 1 release, it features extensive macro functions and Arexx support.
Speaking of communications packages, Microsystems Software shipped The Works Platinum Edition Amiga starter kit with 5 integrated programs for telecommunications, word processing, spreadsheet, database, and printing utilides. MSS will break out versions of Online Platinum and Scribble Platinum at $ 99.95 and 5149-95 respectively. The Works retails for $ 295. Not a bad deal, eh? Online now supports WX, X, Y, Zmodem, Kermit CompuServe B and SADIE (simultaneous file transfer chat) protocols. All die programs are Clipboard- compatible.
WordPerfect held classes in their Theatre, complete with cheering students and free M&Ms. They informally announced PianPerfect for the Amiga.
PlanPerfect is based on the IBM version but it is now entering beta with a completely redone Amiga-tized interface, WordPerfect's next upgrade will be 6.0, not 5.0, and is promised to have an Arexx implementation.
Brown Wagh showed a near-final version of Pen Pal, a clever word processor designed especially for smaller projects in the expanding home-office environment. It can mix text and graphics, import, mailmerge, copy from a built-in database, spellcheck, analyze writing styles, sort by fields, and more. This puppy appears irresistible. It’s fast, sophisticated, and doesn't try to reach beyond its niche, which is basically anybody with $ 149-95 in April.
New Horizons announced a pair of font packages ProFonts 1 with 10 professional fonts for printing, and ProFonts 2 with over 40 decorative fonts for headlines, packaging, covers, etc. Font packages were also available from Free Spirit's Media Line, which is expanding to include clip art and animation backgrouncl I WordPerfect held classes in their Theatre, complete with cheering students andfreeM&Ms, disks. Arock is repackaging its Masterpiece Fonts and Clip Art sets into more manageable 3-disk packs, with six volumes in all.
C Ltd, had their Jet Master font editor on display. Jet Master will interchangeably load and or save fonts in either Amiga screen format or HP LaserJet format. It can do automatic global special effects, like drop shadow's. Jet Master retails for $ 79.95. Also now' available from C Ltd. Is their PrintScript Postscript emulator for the Amiga, a full Postscript interpreter that runs in memory, takes a Postscript file, and prints it on any printer Preferences supports. At $ 89-95, PrintScript has LaserExpress virtual page support.
Making its debut at last was Soft-Logik’s PageStream desktop publishing software, the self-proclaimed Pag- eSetter killer and ProPage rival. The program fully supports dot-matrix printers, rotates text and graphics in any direction in 1-degree increments, allows independent x and y point sizes under mouse or ty'pe-in control, and has the built-in ability' to work with 24-bit color pictures and color postscript directly. The current version does have some bugs, but Soft-Logik promises an update with (continued) more printer support and additional fonts by the middle of April. In the interim,
users are advised to save often and call the Soft-Logik BBS to download PD fonts available there.
Syndesis announced two new modules for Interchange Turbo Silver
3. 0 and Professional Draw. Now all InterFont text and structured
objects can be used with ProDraw, and text can now have up to
16 colors as opposed to Pdraw’s current 2. A 3D wireframe
viewing module is in development.
Syndesis will also release their TSSnet DECnet networking software in the second quarter of'89, letting Amigas become Phase IV end nodes in a DECnet network that can consist of over 64,000 different computers running a wide variety of operating systems. The release will fully support and be bundled with Dale Luck's X-Window system.
Gold Disk was not officially represented at AmiEXPO. However, they did maintain a suite at the Marriott to brief the press and meet with beta-testers and various Amiga luminaries. We were given a preview of several new products in their Home Office Series, including Design 3D, a fast modeling package with a built-in font editor ($ 99-95); Transcript, a fast word processor compatible with Professional Page ($ 69.95); and Advantage, a spreadsheet that apparently can handle unlimited rows and columns and has elaborate charting graphics capability and Arexx support. ($ 79-95 when released in early
summer). Gold Disk is also supporting their release of Professional Draw- with a package of Structured Clip Art (S59.95) and ProPage with their Template and Design Guide ($ 59-95).
Gold Disk did take part in a press conference held on the floor of the show by ASDG, where the two vendors announced support for 24-bit scanned images in the forthcoming Professional Page 1.2 by using ASDG-RF.SEP. ASDG was also bringing their Dual Serial Board to market at $ 299. The board occupies a single expansion slot on the A2000 motherboard and does not prevent function of the original built-in serial port.
Creative Microsystems, Inc. also showed a multifunction board with one parallel port and two serial pons (one being a high-speed AppleTalk-compatible port). The hardware comes bundled with standard serial device drivers and low-level networking software. CM1 also showed the new line of Processor Accelerator + boards for all three Amigas.
The 1000 version has a kickstart ROM socket and a real-time dock compatible with the Commodore A501 dock. The A2000 version goes in the coprocessor slot and has the capability to run RAM at
10. 5 or 14 megahertz.
Memory And Storage Technologies (M.A.S..T.) continues to break the size barrier with their line of hard drives and memory boards. Their Tiny Tiger drives are the only drives that will support all three Amiga models by giving you a SCSI controller through the parallel port. You can also daisy chain off tills unit. M.A.S.T. also showed the prototype for the first one-third height drive, enabling the user to get three hard drives into a one-drive IBM-stvLe expansion box.
Great Valley Products had a huge booth with new products to match. Their 68030 coprocessor accelerator board for the A2000 was being shown in its 25MHz version. It has an asynchronous bus design and, because of the use of special nibble-mode DRAM SIMMS, an effective zero wait-state. The board comes with 32-bit RAM in 4 and SMB configurations.
GVP’s Syquest removable hard drive with its 44 megabyte cartridge automatically recognizes disk changes with GVP's new EPROM auto-boot software kit. A demonstration of their Wangtek 150 meg streaming tape backup system used a port to the Amiga of the UNIX tar utility and standard 3M cartridges.
Gramma Software, hot on the heels of their Nag Plus Schedule Assistant, announced FreD, the speed-dialer program, and NoMo, a hardware device that goes between the audio output of die .-Amiga and your telephone. Used together and or with a modem, they let you use your Amiga to deliver messages to a phone list of people automatically, and they let you use the internal sound chips to send audio over the phone.
With the hardware around $ 25 and FreD near S50 when released in June, the total cost of this Arexx-driven system is less than almost any modem.
Indeed the Arexx environment took great strides in die months since AmiEXPO LA, Programs shown at New York with Arexx ports included Nag Plus, FreD, ASDG’s CygnusEd Professional, and PageRender 3D, a new ray- tracing package from Mindware. Also coming with Arexx in June is 3D Professional from Cryogenic Software, to be marketed by Progressive Peripherals.
Seen talking Arexx on the floor were Dan Browning of Precision (SuperBase Pro and SuperPlan) and Gary Samad of Software Visions (Microfiche Filer Plus). Samad announced the imminent release of the first two Designer Database disks, with Arexx-driven databases for Home and Business. Aid Emerald Intelligence took time out from showing dieir (gasp) Mac version of Magellan to promise dieir Revision 1.1 with Aexx will be shipping soon. They were also hinting at a port of a program coming the other way around from the Macintosh environment. Wonder what “card" they have up their sleeve?
Music, Music, Music .Another program originally on the Mac and now available on die Aniga is Intelligent Computer Music System's M, the interactive composing and performing MIDI software. Dr. T’s showed their Level II sequencer, which adds die Programmable Variations Generator and the Master Editor to KCS
VI. 6A. New Wave Software released Dynamic Studio 3.0, with a
redesigned WYSIWYG user interface, increased resolution,
auto-quantizing, and the ability to make eidier global or
specific changes with mouse control. Impulse will release a
hardware soltware package called Harmony which will allow you
to input vocals and humming or whisding and output MIDI
And last but not least, Mindware is readying an add-on to PageFlipper Plus called PageSync. It will let you synchronize MIDI events and sound effects in real dme or under script control.
The story of .AmiEXPO NY '89 was one of growth, consolidation, and interconnectivity. As much went on in the hallways and suites of the Marriot Marquis as did on the floor and in the well-attended seminars and master classes. Commodore was represented unofficially by Gail Wellington, Lauren Brown, Carolyn Scheppner, Andy Finkel, Steve Beats, Dave Haynie, Dave Bere- zowski, Bill Kocster, Bryce Nesbitt, and CBMers from Sweden, Spain. Switzerland, and Germany. Seen here and there were Joltn Toebes at the Lattice booth, Jim Goodnow promising Manx 5.0 this summer, VirusX’s Steve Tibbett,

Landis, Steve Segal, Jim Sachs, and Louis Markova, the latter showing some incredible 3D images at the Haitex booth.
There were some new faces, too.
Teller of Penn and Teller visited the NewTek booth, along with Dana Carvey, Saturday Night Live cast member and brother of NewTek engineer Brad Carvey. Teller, as usual, wasn’t talking, but Steve Young, senior correspondent for CNN Business News, was.
After a private preview of Gold Disk’s parade of budget business software and a whirlwind Sculpt 4D-tour, Young paused to catch his breath. “I saw in the graphics area remarkable applications not equalled at anything like die price point." He shook his head in bemused wonder: 'The cost of hardware and software is quantitatively less, yet with such a small user base. I am puzzled as to how the Amiga developers are able to produce at such a low price, or conversely how IBM and Apple are not."
Good question, Steve, and one that will be answered more and more as the Amiga gets serious. Meanwhile, like the song says, "It's up to you... Start spreading die news..." 77?is stoty is based on the reporting of larry While, Tina Chase, Steve Gillmor and Don Hicks.

(703) 536-5040 AmiEXPO Art and Video Contest Winners by Steve
Jacobs AmiEXPO has always had an Art and Video Theatre
where convention attendees could view slide shows and
animations produced by fellow Amigans across the country.
After our third convention, we decided to establish an art
contest in conjunction with the NewYork show this past
month. The contest was announced in the fourth quarter of
1988 and the rules and guidelines were distributed at the
Los Angeles AmiEXPO and at AmiFORUM.
The Amiga press was kind enough to carry our press releases, and hundreds of requests for entry forms came into die office.
Frequendy, contests have categories arranged around diemes or types of art, for example, “Fine Art”, “Commercial Art”, or “Cartoon”. However, i had no idea what range our entries would cover.
Therefore, I arranged die categories in a slightly different manner.
The contest was organized over five categories. The Art categories were “2D’’ (for art created with the wide variety of Amiga “paint” programs), “3D’' (for art created using die wide variety of three-dimensional rendering and ray- tracing packages on the Amiga), and “Digitized” (for works using digitization as part or all of die creative process).
The “Video” categories were “Mixed Media” (for works combining computergenerated video with live or prerecorded video), and “Animation” (for purely computer-generated pieces).
I was pleased to find we received a wide variety of material. (I was deeply fearfui of die possibility of receiving 200 science fiction illustrations). We had abstracts, commercial pieces, cartoons, photo-realistic pieces, and pieces with a “water-color" feel to them. (The judges remarked tiiat several entries had an “oil- on-velvet" feel to diem as well. This was not a compliment.)
Most Amiga animation contests have been built around disk-based animations. I required all animation submissions be on videotape. There were two reasons for this. First, disk- based animations are limited to a certain size and length. Though new programs like MovieSetter and the soon to be released Blacklight are stretching these lengdis to minutes, the limits remain. The second consideration was disk load time.
In terms of judging, the more complex animations take longer to load than play.
When you have a group of people watching monitor screens for hours on end, loading time becomes a big factor in sustaining audience attention.
Goals for the Contest I had several different goals for the contest. First, I saw the contest as a way of getting more publicity for die artists. I required the artists give me the rights to distribute their work to the magazines.
The artists retained their copyrights, though. They were not asked to either put dieir work in the public domain or surrender diem to AmiEXPO. I believe it’s important for people to retain the rights to tiieir own work.
(continued) “Overall, over two hundred Amiga enthusiasts entered the contest.
Over 350 images were submitted in the art categories, and over 35 ivorks were entered in the Animation and Mixed-Media categories, for a total of two hours viewing time. ” I also tried to sign on judges from outside the Amiga community and or judges well-known in their own right. I thought this would improve the chances of getting magazines outside the Amiga community interested in covering die Amiga. I was able to get several “heavy hitters” as judges. This was another reason for refusing disk-based animations. You cannot impress judges used to high-end equipment widi thirty-second
animation loops lhat take five minutes to load.
Entries and Systems The entries came from across die broad spectrum of the Amiga community. People of all ages from the continental U.S., Hawaii and Canada entered die contest. A third of the contest entries came from women. At a time when die New York Times is ninning articles about die lack of female involvement widi computers nationwide, this a very exciting bit of news.
Our artists included both professional artists and novices. Stand-out entries included a series of pictures from a Long Island high school Amiga art lab, and a nun who runs an Amiga users group in her Upper West Side church.
Overall, over two hundred Amiga enthusiasts entered the contest. Over 350 images were submitted in die art categories, and over 35 works were entered in the Animadon and Mlxed- Media categories, for a total of two hours viewing time. Winning entries, as well as, a selection of odier submissions, were shown in the AmiEXPO Theatre during die three days of die show.
If our entrants qualify as a representative sample of Amiga owners, there's still a large number of active 1000’s out diere (including die one sitting on my desk). Most entrants had some type of upgraded memory for their systems. Over 90% drew dieir creations with a mouse.
There are two items almost every Amigan owns. The first is Deluxe Paint
n. The second is Digi-View. Almost as popular with our entrants
were Photon Paint and Pixmate. In die 3D category, Sculpt 3D
and Animate 3D were used a little more often tiian Turbo
Silver. In die Animation Categories, there were no packages
that stood out as most frequently used. Several entrants
actually wrote dieir own software as part of their entries.
The Judging and the Judge The judging was held on February 19th at Mission Graphics Support, Inc. in Manhattan. We did attract some high caliber judges. Our first judge, Diane Kadah, is President of die New York Chapter of the National Computer Graphics Association. She is also a presentation graphics consultant. Our second judge, Issac Victor Kerlow, is Director of die Computer Graphics Lab at Prau Institute in New York City. Fie is also an author of computer graphics texts and a well-known artist in computer graphics circles. Perry Hoberman, the diird judge, is known for his stereoscopic
computer art and performance art. Acting as fourth judge, Vincent Billota is Director of Graphics and Animation for Mission Graphics Support, Inc., a Lower East Side Amiga dealership specializing in high-end video workstations. Vincent has been instrumental in developing the New York Amiga animation scene. I was the fifth judge.
From 1:00 p.m. to 6:30 p.m., we stared at monitors until our eyes were a bright pink. The still images filled almost 20 megabytes of the GVP Impact 500 used to display them. We alternated video and still categories for a change of pace. The judges chose a 1st, 2nd and 3rd place winner for each category, with several pieces being selected for “honorable mention”. With most of the categories, the judges were able to come to a consensus without having to “grade" or number die entries.
The winners were announced and shown after Gail Wellington's keynote speech Friday afternoon. First prize winners received computer hardware and software specific to the category. In addition, first, second and diird place winners in each category were awarded plaques honoring their achievements.
The winning entries stress the versatility of the Amiga. The winning 3D entry required an Amiga 2000 widi tons of RAM and an accelerator. The winning 2D entry was produced on an Amiga 500 upgraded to one meg of RAM and Dpaint n. Tips On Entering Next Year’s Contest!
I’d like to take a moment to give you a few pieces of advise to help you in submitting your artwork. These apply not only to die AmiEXPO Theatre and next year’s contest, but to other contests and exhibitions as well.
First and foremost, READ THE RULES!!! Most professional contests will simply refuse to even look at your work, let alone judge it, if you haven’t followed all contest rules EXACTLY. Several disks and tapes we received could not be used because they did not meet the categories as oudined in the rules. The winning animation entry was incorrectiy submitted as a mixed-media entry. If you're not sure which category to submit your work to, call die organizer and ask. DON'T send multiple disks of the same work to each category.
Fill out the entry form completely.
THINK about the questions and, if you're not sure how to answer them, call die organizer and ask. On the entry form for die AmiEXPO contest, I asked entrants to describe “the hardware and software" used to make the piece. Twenty-five entrants neglected to tell us which Amiga they used and simply listed their software.
.Also, try to use standard formats and screen sizes for your work. Several people submitted pages larger than die screen or pieces made in beta tests of software not yet released. Due to time limitations, exceptions could not be made to show to judges work that could not be displayed in a slide show program, If your work needs special attention in order to be displayed, (e.g., multiple monitors, scrolling around die screen, 3D glasses) call die contest organizer before submitting your work.
If there are several different categories of disk-based work, submit the pieces for each category (no matter how many or few) on a separate disk. If your pieces are going to be loaded onto a hard drive for exhibition, diis makes it easier for the contest organizer to load die work into the individual directories.
Label the disk widi your name and phone number, die names of the pictures on the disk, and the category you are submitting diem to.

Even if it’s a fully computer-generated visual, there should be some kind of sound or music added later on. It doesn't have to
be created by the computer. Simply adding sound from records or tapes can greatly improve how your work is viewed by others.
Animation is an audio-visual medium.
Submit your work on 3 4" tape if at all humanly possible. Yes, it’s expensive.
And yes, it may be hard to find (though most major cities have artists access centers for film and video, and most colleges have 3 4" equipment). The point is VHS video is lousy video in Lerms of its signal. Just because it looks OK at home doesn’t mean all is right with the world.
The videotape you submit to a contest will most likely be dubbed (copied) into a loop of all the entries for viewing purposes. VHS does not copy well. If your video comes straight out of tire computer onto VHS, and you send the original, tire signal will be OK. Most people will send a copy of the original.
That means the copy will then be copied again into the loop. This means you've already lost some picture quality. If you are editing pieces together (1st copy), then copying the edited version (2nd copy) to send to the contest (3rd copy), your piece may already be unviewable. If you’ve been using cheap tape, you are definitely wasting your energy.
The bottom line is, this is YOUR work. If you want it seen in the best possible light, you should spend the extra time and money and do it right.
There will be another AmiEXPO Art and Video Contest next year. As this article is being written two days after AmiEXPO New York closed, I cannot give you dates or categories at this time.
Look for them soon in another issue.
There will be another version of the AmiEXPO Theatre being shown at AmiEXPO Chicago, July 28-30th. If you’d like your work to be considered for exhibition, send me stills on disk and moving images on tape by July 1st.

SYNC TIPS Resolution, resolution, wherefore art. Thou, my resolution?
By Oran], Sands, III If there is one topic of video and computing that is continually misunderstood, it’s resolution. For some reason, resolution seems to be a moving target.
No sooner do you come to understand it, the rules seem to change. Well, this month we're going to tackle the issue of how to measure resolution, and why. So sit back and fasten your seat belt. This could be a bumpy ride.
There seem to be a thousand different ways to measure resolution, and a hundred different units of measure.
Linepairs, lines, pixels, and bandwidth, are just a few of the more commonly used units you’ll find when shopping or comparing video and computer gear.
Remember that all resolutions aren't created equal. Just because two pieces of equipment have the same number listed under tire specification of ‘‘Resolution’’, they don’t necessarily have the same actual resolution.
When we say “resolution", we mean picture sharpness: How “crisp" is the picture? How much detail does it have? It is absolutely necessary to have some way of comparing pictures and the equipment that produces them. Since eveiyr type of equipment has its own method of measurement for resolution specs, we’ll tackle each piece one by one.
Video Measurement We’ll look at video resolutions first.
The most common way to quote video resolution is to measure it vertically and horizontally. Although it is possible to measure the resolution of both the luminance (brightness) and chrominance components of the video signal, we most often deal with those figures pertaining to the luminance. These figures are always the higher of the two, and more accurately reflect the signal’s ability to convey information.
NTSC video defines the picture area vertically by the number of scan- lines, and horizontally by the time it takes to scan from left to right across the screen. Theoretically, these are the maximums our resolution specs can attain. But actually, that’s not the case.
NTSC standards demand using several scanlines for sync and other special information, but not for video. Because of this, the number of vertical scanlines reduces to only 482 scanlines for displaying video. The time allotted for a horizontal scanline to cross the screen is 63 microseconds but, again, due to color standards, the actual time available for displaying video is closer to 52 microseconds (often rounded off to 50 for calculation purposes). This is the “active video’’ time (see figure one). So you can see that, when measuring video resolution, it’s necessary to know what you’re
actually measuring.
Now the actual measurement is fairly simple. All video equipment (in the US, Canada, and Japan) uses the same number of scanlines, top-to-bottom, so this figure usually isn’t quoted. Horizontal resolution is our important spec, so let's talk about that first.
Horizontal Video Resolution We measure video horizontal resolution in lines. This measurement refers only to tire Luminance component of the video signal. If we aim a camera at a chart composed of evenly spaced black and white lines stood on end, our horizontal scanline would cross these lines as illustrated (see figure rwo). If we could slowly push these lines closer together, the camera would eventually reach a point where it would no longer be able to clearly distinguish between each black and white line. The result would be a gray smear, This is our point of maximum resolution. If we count
all the lines both black and white that the camera can see in one scan, we then have our measurement of resolution.
(continued) The video scanline sweeps from left to right as it records or displays a picture.
As it encounters light or dark subjects, it produces high voltage for the white areas and low voltage for the dark. The quicker the scanline encounters these light-dark alternations, the more difficult it is for die electronics to produce die electrical waveform that becomes our video signal. We soon reach a point where die electronics can no longer accurately reproduce the level of detail we need. This, again, is our point of maximum resolution. For each swing of voltage, from positive to negative, die Just because two pieces of equipment have the same number listed under the specification of
“Resolution’1, they don’t necessarily have the same actual resolution.
All resolutions aren't created equal waveform completes one cycle.
The time it takes this cycle to occur can be used to calculate die frequency (number of cycles per second) of die video signal. If this is done for the waveform at maximum resolution, we then have a frequency rating widi which we can use to quote resolution. A shorthand mediod of calculating this is to figure diere is 1MHz of bandwidth for every 80 lines of resolution (per picture height, the standard measurement, remember?). This method results in a number in megahertz, and is known as die bandwidth. A VCR with 240 lines of resolution has a bandwidth of 3-0 Mhz.
It is often used in the broadcast industry to describe various pieces of equipment.
NOTE: There are many incorrect assumptions about how to measure video resolution. Supposedly, all we have to do is count how many lines are viewable in one pass of the scanline to get our resolution spec. But do we count the number of white lines, the number of black lines, or both? For video measurement, we count each white AND black line. In film, you count line pairs to measure resolution. This procedure has confused some. Each black and each white line counts for video.
Caveat Emptor Now that we know what to count, it seems simple to get our measurement spec. However, it’s not as simple as counting the number of lines resolvable within a horizontal scan. If die number of lines is 800, we could use that number as the resolution, measured in lines per picture width. Unfortunately, this isn’t the way video resolution is usually quoted.
Since the aspect ratio of screen height to screen width is 3:4, the industry measures the number of lines counted in 3 4 or 75% of the picture width. So our number of 800 now becomes 600. When measuring resolution like this, die measurement is in lines per picture height. Although this may seem odd, Uiis is the way it’s done.
Let’s look at the vertical video resolution briefly. I alluded to vertical measurements as unnecessary when dealing with only NTSC systems since die number of scanlines is always the same. Yet sometimes, you’ll see the vertical spec quoted as a number from 480 to 525- This is only because whoever did die counting didn’t know when to quit (or start). All these numbers represent the same resoludon, for the most part.
Sometimes, though, you'll see the number quoted as 350 lines. This is because 480 scanlines can’t see 480 lines unless diey happen to fall direcdy upon the scanlines.
Realistically, they are just as likely to fall between them. The engineers have a way of determining what the average works out to. It's about 350 Lines. So, if you see diat number, you’ll know where it came from and how it compares to the 480 figure you'll see more often.

1. Video horizontal resolution is measured by counting the number
of dearly reproduced lines (black and white) in the “acbve"
video area of one scanline.
2. This number of lines is known as “lines per picture widdi”.
3. Video horizontal resolution is most commonly quoted in "lines
per picture" height, which is 75% of the number of lines per
picture width.
4. The number of lines converts to a frequency rating called the
Computers We all think we know how to measure computer resolution but, again, we all get bitten by a few misconcep- dons. We measure horizontal resolution by die maximum number of pixels displayed on one horizontal line. So far, that sounds much like the way we start measuring video. But diat number describes only die number of pixels inside the Amiga's borders (or those on any other computer widi a bordered screen display).
The border itself is “active" video area. We need to count the pixels in this area also to come up with a number comparable to the video measurement mediods. Fortunately for us, the Amiga can address that border area, and we should count it as our display area.
Although we may program die Amiga to display a picture with a width of 768 pixels, closer examination finds diat width violates some NTSC standards for horizontal line width. To keep our screen width widiin standards, die maximum number is closer to 719 pixels.
Now -we have a measurement comparable to the video measurement of “lines per picture width”. Converting it to a number measured in “lines per picture height", die standard measurement would be done by multiplying it by 3 4.
Or you could convert the video number to “lines per picture width” by multiplying by 4 3. Just keep in mind that the video resolution is always quoted in “lines per picture height”, which is the smaller number of the two methods.
OK. Let’s wrap it up again. Here is a conversion formula to equate computer and video resolutions.
Lines per picture height = (.75) x Lines per picture width= (.75) x Total number of pixels for a full screen (addressable or not).
Or (4 3) x Lines (per picture height)= Lines (per picture width)- Total number of pixels for a full screen.
Let’s run some numbers by just for fun. If the Amiga's maximum resolution is 719 pixels, dien multiplying that by .75 will give us 539.25 lines (per picture height), in video terms, that’s not a bad resolution figure. Converting that to a bandwidth figure gives us 6.7MHz. Adding resolutions Now that we know how to compare them, let’s look at how the resolutions of various pieces of a video system will affect our picture. For the following examples, well assume the figures represent comparable resolutions.
If you have a camera whose spec is 600 lines and a VCR with a resolution of 240 lines, and you put the two together to record a picture, what is die resolution of the final image?
A. 600 lines
b. 240 lines
c. fewer dian 200 If you answered b (as most do), you probably
subscribe to the bucket theory of resolution addition. Stated
simply, if you had 600 gallons of water and you poured the
water into a 240 gallon bucket, you’d get only 240 gallons
left (and a mess on the floor). Unfortunately, this isn’t
how it works. Although it’s hard to find a real consensus
among engineers on this subject, most do agree that
resolutions add like electrical resistors in parallel. For you
nonengineer types, the following formula sums it up.
1 Total effective resolution
(2. 4MHz). So, if all things were ideal, we’d have a maximum
viewable picture with 200 lines of resolution on our TV.
Since tilings aren't ideal, we end up with fewer.
It’s possible to get better resolution from your TV if you use a more difficult (and more expensive) system for separating the color and brightness components. This is called “combing” as it uses a “comb” filter to keep the components apart, but intact. Sets using this process can show as much resolution as they get. But remember, if it’s broadcast, then diat's still only 330 lines, as mandated by die FCC.
NOTE: The FCC limits the resolution to keep the broadcasters’transmitted signal from exceeding their allotted channel space. Adjacent channels would intetfere with each other if the resolution was greater.
Nanosecond Measurement One other method of measuring resolution is to refer to die smallest piece of picture your computer or character generator or paintbox can create, the pixel, and then state the amount of time l resl+ l res2 +....+ 1 resN To use our example we get: 1 Total = 1 600 + 1 240= .001666+ ,004166=.0058326 Juggling the equation gives us Total = 1 .0058326 = 171.45 lines. You can see that things get worse much quicker than you’d expect. How can we combat this problem? By making sure our resolution is as high as possible for every piece of equipment we buy. It's this reason
(among others) that broadcasters pay astronomical prices for their equipment. There's another reason also.
NTSC and the FCC Scanned area Broadcasters have to use the NTSC signal to get the TV picture to your television, and several compromises are made on die way. The NTSC signal is capable of carrying high resolutions, over 1000 lines or more. Studio cameras are easily available with resolutions exceeding 800 lines. But due to FCC standards, you can’t broadcast a signal exceeding 330 lines (4.2 Mhz). So the transmitter limits the resolution to 330 lines. With our formula for adding resolutions, we can see we need as much res as possible to assure our actual transmitted signal will approach the 330
lines we are allowed. After it receives die signal, another compromise is made within your television.
¦77777777-77777777777 | J j - I ' - 5 ZZZZ2ZZZ222Z2ZZZZ Active video area Tv Screen Scanline The transmitted signal converts back to die original NTSC signal the broadcaster started with, minus some resolution. Then the NTSC signal decodes into its luminance and chrominance components. Unfortunately, in order to easily (and cheaply) separate diose components, the resolution is again reduced, this time to 200 lines needed to display it. This figure would be very small, measured in nanoseconds(ns). One nanosecond is one thousandth of a millionth of a second. You often see this figure when
comparing resolutions of character generators or broadcast-quaiiLy computer graphics systems. The most common figure is 35 ns. Since 1428 pixels of 35 nanosecond w'iddi can be put on a 50 microsecond video scanline, that resolution is about twice the Amiga’s (at over 700). So the Amiga’s resolution is about 70 ns. (Just in case someone asks.)
Camera Voltage Conclusions Let's wrap it all up.
Video resolution measures by lines per picture height which is 3 4 of the actual number of lines measured on a horizontal scanline.
For every 80 lines you measure, you get 1MHz of bandwidth.
Computer resolution measures die number of pixels on a scanline within the borders of the display area.
The minimum time it takes to display a pixel is often measured in nanoseconds.
I’ve included a chart of common resolution measurements for your use. I (continued) Figure One Active Video Area NTSC standards demand using several scanlines for sync and other special information, but not for video. Because of this, die number of vertical scanlines reduces to only 482 scanlines for displaying video.
- Figure Two Horizontal Video Resolution If we count all the
lines both black and white that die camera can see in one
scan, we tiien have our measurement of resolution.

It's quite straightforward. Still, many computer and television engineers don't even know how to relate one type of resolution to another. I must admit to discovering a few tilings myself while researching this column. Just follow the conversions I have provided and you’ll always be speaking the same language.
I'd like to thank Rick Seaman and Greg Sorenson of Magni, Inc., Steve Brandt of Tektronix, and Dave Duffield of Thompson Consumer Electronics (aka RCA) for their patience and help in putting together this material (to say nothing of their amazement that anyone would attempt to put all this in one column).
Coming up soon: Interlace. Why have it?
VidBits If you haven't been to your dealer lately, you probably haven’t seen die new 1084S “D" monitor. Although the designation is the same, the monitor isn’t. Oldtimers will recognize the old 1080 monitor, which in most users’ opinions had higher resolution than the original 1084. The updated “1080” has been equipped widi stereo speakers.
Also, the bright, sharp screen we used to know is there. Congratulations Commodore, for opting for quality!
Congrats also to Shereff Systems for offering a new character generator program so soon on the heels of dieir last entry. Pro Video Gold replaces Pro Video Pius (I can't wait for programs and hardware with a SUPER DELUXE tag on their names). Pro Video Gold features all the incredible functions and abilities of PV+, with and-aliasing and severe overscan operadon added. Anti-aliasing means your fonts will look as if they were drawn using more and smaller pixels than are available. Smoodier curves and slanted lines drastically improve the text on your screen.
Aldiough Broadcast Tider is said to offer diis feature, it looks as if Shereff Systems will get it to the market first. A complaint of PV+ users was that any IFF pics used for backgrounds were limited in size to 672 x 440 pixels. Now you can use the Deluxe Paint default for video page size, 704 x 480. This should help improve the coverage of a background picture.
Registered users of PV+ should know they can upgrade to GOLD for only a small charge (10 or 15 bux).
One last note: Many users have found that the 2090A hard drive controller card has a timing problem when working with overscan programs. Pro Video Gold has taken steps to avoid the problem, and now report diat a 100-page job save is quicker dian ever. In fact, on an Amiga 2500, expect it to be as litde as 2 seconds!

sale? Wei!, they haven’t exactly broadcasted it, blit a couple
of the larger software developers who made their names in the
.Amiga market are entertaining offers. No names, please it’s
a delicate situation. Kind of like those anonymous personal

software firm with large distribution.
Must like graphics, computer music, animation and undercapitalized companies with cashflow pivblems.
Object: matrimony. Send reply and photo to Box A.” Some interest from the big software companies on the make, but no firm offers yet.
Why are these Amiga software developers for sale? The pat answer is that sales are poor. But that's only a surface explanation. Mismanagement is closer to the mark, since most companies are experiencing strong Amiga software sales now. Their failure appears to be the result of overly aggressive spending on marketing and new product development, combined with a failure to get the products out to help pay for it. A sure warning sign of such problems: lots of advertising (for many months) for products that haven’t yet shipped, indicating that marketing is sadly out of sync with product
Latest news in die video game shootout: Atari Corporation (not Atari Games, but the makers of the ST you remember the ST.) has filed an antitrust suit against Nintendo for a cool $ 250 million dollars. According to Atari's statement, Nintendo prevents developers from selling versions of Nintendo games to other video game companies. In effect, Nintendo is keeping a stable of developers to itself.
More to the point, Atari can’t publish 2600 or 5200 versions of the best-selling Nintendo games. So Atari is trying to get Nintendo to allow that while, at die same time, Atari Games is trying to get the right to make Nintendo cartridge clones. Nintendo called Atari's suit Tneridess and simply an attempt to excuse Atari’s poor competitive performance in the marketplace." Ouch. Adding insult to insult, Howard Lincoln, Nintendo's senior vice-president, said, “Atari’s lawsuit is simply sour grapes by a company that has failed to capitalize on its past position as the market leader," The days
of whine and roses are over, it seems.
Ihe games that time forgot Not to be outdone in the armaments battle, Nintendo has fired a long- range cruise lawsuit at Atari Games, charging patent infringement. This, of course, refers to those cartridge clones that Atari Games is now manufacturing.
This whole affair reminds the Bandito of dinosaurs balding in the swamps, while fearful computer game software companies play die role of the mammals cowering in the mud waiting to go in and gnaw at die bones of the defeated behemoths.
Taking die analogy' a bit further, diose old Atari cartridges, which became landfill in Arizona after the first Videogame Crash, turned into the metaphorical oil diat fueled die growth of die entertainment software business. Nintendo is fighting to keep from becoming the gasoline of the next generation, and to keep their machines out of the Cabbage Patch (that is from 1 toy one Cliristmas, to Chapter 11 die next). Of course, their executives will tell you at length how Nintendo isn't really a craze it's different, and lasting: an enduring monument to man's creativity7, diat sort of thing
(well, maybe not in those words). Seems to the Bandito those same descriptions were being used in die early ’80s in Atari’s heyday, right before the Crash. Funny thing, Nintendo’s sales for last year were getting close to what Atari’s were at die peak of then' business.
Remember what Santayana said about history repeating.
Seems like there's a new strategy7 in the computer business if you can’t beat ’em, sue 'em. Apple is trying that tactic right now against Microsoft and Hewlett-Packard. It’s happened (and is happening now) in the Amiga market, too. The Bandito thinks companies who believe lawsuits are the road to riches should spend their money on new product development, rather dian on lawyers. Give up the lawyer racket and get an honest job like figuring out how to get kids to part with three months of lawn-mowing money for die latest shoot- ’em-up game.
Color fax machines are on the drawing boards now that the fax machine market is in high gear. What could better serve as the basis for a color fax setup dian an Amiga? Maybe some bright engineer will make a faxmodem card for the A2000, and support color.
With that and a digitizer, you’re all set.
The Bandito hopes that someone goes to work on this right away7, so die Bandito can send color junkfax for Christmas.
More software imports are coming from Germany and England. U.S. companies are looking to Europe for more Amiga products, since they cost less (for the most part). Expect to see distribution deals inked soon between some of the small European companies who have tried to market their stuff here and established American companies like Electronic Arts and Cinemaware, among others. For the eager game consumer, this means even more game software dian before. Still no assurance of quality though. It’s a veritable minefield out diere on the retailers’ shelves, and packaging is no help. Some of the
best games hide in die most atrocious wrappings, while many7 a lovely cover conceals Commodore 64 games clumsily ported to AmigaBASlC. This is where it really helps to have a local retailer w7bo is w'iliing to take a game out of tire wrapper and show it off, so yrou can take a look before you buy.

Suite 223 nramma Scaule, Washington 98155 VJ (2fxj} 363-6417 While the Banciito dearly loves games and wishes more of them would multitask discretely, a few things could be improved. Game makers, it’s OK to use digitized images, but make sure you clean them up, ail right? Nothing is tackier than a sloppy digitized face or background. And if you must port a game from another CPU, bring the graphics and sound (if not the gameplay) up to the level of the Amiga. The Bandito could forgive some of the transgressions in the
early days of the Amiga (Seven Cities of Gold comes to mind as a painful example) as youthful exuberance, but there's no excuse anymore. The Bandito is ready to scream at the next Sega game port seen on an Amiga monitor. Few tilings are more terrifying than seeing the Amiga being cruelly transformed into a Sega game machine. Have a heart, fellas.
On the brighter side, have you noticed how more games are really using the Amiga's power? In recent game releases, the Bandito has seen overscan, extra halfbrite, HAM, continuous sound tracks, and stereo sound effects. Not all in the same game, of course, but perhaps someday. The ultimate game experience is an Amiga hooked up to a giant-size TV with a heavy-duty sound system. Those pixels practically crawl right out and grab you. If you have that, who needs to go to an arcade?
Commodore Productivity The latest news about Commodore is very good. In a recent study measuring productivity of computer companies by sales per employee, Commodore came out 2, right behind Apple. IBM was a distant, dismal also-ran. Commodore is running lean and mean these days, and is racing to get rid of the debt they acquired. Did you see the latest stock quotes? Commodore stock almost hit 18, which is amazing for a stock that bottomed out at 4 a couple of years ago.
The Bandlto thinks you should stick around for the ride next stop, $ 35 share.
All this is music to the ears of the old Amiga employees who held on to their Commodore stock. You see, they got paid for Amiga in Commodore stock and extensive options at around S10 a share (some were at $ 12), and after the deal was consummated, Commodore Pf&aso dow tout to six wooks for ptoco&rg.
Stock promptly dropped down to the $ 5 range and stayed there for years. Now, the original Amigans can finally get some profit out of the deal. That is, if they didn’t already sell the stock... An easier hard drive setup?
On the hardware side, the Bandito has been hearing some gnimbllng about how difficult hard drive setup is. While it’s not quite as arcane as configuring an IBM hard drive, it's pretty darn close.
That's one advantage the Macintosh has their hard disks come preformaned, just plug and play. Of course, they’re more expensive, too. Anyway, Commodore should work on the WorkBench and their hard disk setup. The Bandito would settle for having an easy-to-use piece of software that holds your hand through the setup process.
Any chance that Commodore will do tills, or will the third-party developers (as usual) beat them to the punch?
There's no reason why Amiga can't make the process easy and give you more control over how you want to partition your hard drive. Let’s be the leader of the pack, rather than the follower.
While you’re at it, make sure tiiat icons are always created for files. Why force everybody to go to the CLI to find a file? On the Mac, everything has an icon. Even if the program doesn't provide for it, the system software takes care of it. The Amiga should do tliis as part of die project to make life easier for new Amiga owners. Let’s not force everybody to become CLI wizards. If you want to do that, buy an IBM.
680) 0 Amiga?
Speaking of leadership, how about getting the 68030 Amiga to hit the market this year, widi Commodore putting some marketing behind id With die right addons, diey could really go after some of the Mac and IBM workstation markets.
Besides, die 68030 means hardware memory management, which can make multitasking bulletproof. Commodore should look to the future and try to standardize on that platform, so .Amiga- DOS can really kick butt. OS 2 is off to a slow start, and Apple needs to rewrite their System software entirely, which will take them a couple of years. It’s a golden opportunity for Commodore to really get (continued) ahead in the marketplace. Think of how the software would shine on a 68030 platform! Maybe it will come down to a price that the Bandito can afford. By the way, it looks tike Commodore has a hit
with their new 68020 Amiga. The A2500 is shipping as fast as they can build diem. Give those customers a little power, and they'll want even more.
Think what a 68030 version would do.
At the odier end of the hardware spectrum, Commodore is preparing for die impending arrival of Amigas in the mass market chains. Will there be a lower-cost A500 or the videogame version that the Bandito heard about?
The jury's still out at Commodore, though efforts are continuing to reduce the manufacturing cost of die A500.
Some people inside Westchester are now calling for turning the C64 into die dedicated game machine radier dian the A500. After all, it is better than a Nintendo. There is already a big installed base of hardware and software, the distribution is already in place, and the profit margins are there. All that needs to be done is some re-engineering of die C64 and getting die software manufacturers to put their games on a cartridge.
Commodore may have to do that to keep die C64 alive. Although it had a good Cliristmas, observers are wondering if the venerable 64 can make it through another year.
Finally filling the slot left by Tom Rattigan’s departure, there’s a new' president at Commodore: Mehdi Ali, former managing director of Dillon, Read in NY. Odier past work experience includes VP at GM and PepsiCo (take diat, John Sculley).
Commodore is getting more aggressive about their PR efforts, which is good news. Part of die reason you’ve seldom seen articles about Commodore in the mass media in die past is they’ve been very tight about letdng sample Amigas go to members of the press.
Now, Commodore is loosening up a bit, and more hardware is going to important magazines (especially professional magazines). Now the magazines can review the Amiga and its software and hardware add-ons and, as a consequence, Commodore is getting more press. We may yet see Commodore accorded the same recognition Apple gets, which is far too much if you ask the Bandito. Apple's success with die press stems mainly from its cute name and the fact that it was started in a garage.
The list of Amiga developers trying to make money in the Mac market is growing, but none of them have yet turned a good profit. Marketing costs are very high (about the same as in die IBM market), and diey don’t seem to realize it’s getting tougher ail die time to break in.

Apple IIGS sales are reportedly slowing down in a big way, In fact, the situation is getting serious for die whole Apple If line. Hardware and software sales have slowed to a crawl, and none of die big software companies are developing any important new software for die IIGS platform. They’ve already reached the performance limits of the machine, and die software they have doesn't sell very well, so why bother?
The problems go even deeper.
Pressure is building at Apple to bring out a $ 1000 retail price Mac Plus, and get rid of the Apple II line for good. They may do it as early as January 1990. What does this mean for the Amiga? Just diat one more competitor for the home market bites the dust, leaving Amiga battling against the Clone Armies.
While die Clones have tremendous numbers, when you get down to price performance, die Amiga 500 competes very well. Let’s say you can get an A500 widi 1 meg, two drives, and monitor for $ 1200, while you can get a Clone widi a 10 Mhz 8088, 640K, a 360K drive and a 720K 3.5" drive, and an EGA monitor and EGA card for about S1200.

If Commodore can get the word out, why should anybody buy a Clone for their home? Oh, wait, there is one thing data, compatibility7 with their MS- DOS machine at work. Well, Central Point’s DOS-to-DOS can fix that. Better yet, maybe Commodore should buy the rights and make it official, or come out with their own version. Then the Amiga could really go for the throat of the home market.
A HyperCard clone for the Amiga?
Several contenders are testing versions right now. The Amiga makes a much nicer platform, what with animation, stereo sound, and color graphics standard. Why should the Mac have all the fun?
In the realm of financial reports, Mediagenic had a dismal holiday. They reported net income fell in the Xmas quarter, while sales rose. Sales for the quarter were $ 19-2 million vs. $ 12.2 million for tire year earlier, while income is 56QOK versus S800K for the year earlier. That’s not much of a profit margin to write home about. But they’re trying to revamp their product lines, ancl are promising some really good games for die end of the year. We’ll see.
More from the Battlefield Paint Wars Batdefieid Update: It looks like April is show7 dme, wdien all the major contenders will take die field to battle for market share. In an interesting new twist, it looks like DeluxePaint III will actually get some advertising, though it’s not nailed down yet. Until dien, everybody’s paint program sales have slowed down in anticipation of the new versions. Once again, the consumer will be the winner in the feature-packed battle for control of the graphics market.
Stay tuned to this Bat-channel for details.
One developer is trying to get aw7ay from the Amiga name in a professional market, and they rejected an offer to show7 in Commodore's booth at an upcoming trade show. They didn't w7ant to be associated with the Commodore name; they’re afraid the buyers w7on’t take them seriously. You’d think Commodore would take a hint.
The latest word from Epyx is their top-secret project is definitely a videogame. The bizarre twist in this is the Bandito’s informant swears up and dowrn (in x and y, that is) that it’s a handheld device. What's that? A controller, or the actual game unit? What kind of screen does it have? Curiouser and curiouser, says the Bandito. When the data get weird, the weird get data.
According to an internal memo.
Commodore has shipped the magic millionth Amiga (that's shipped, not sold). Congratulations! That should make more developers sit up and take notice.
Just to put things in perspective, diere’s a little over 2 million Macs in the world, and about 18 million IBM clones. On the other hand, diere’s only 800,000 laser disc players. One million is a very respectable number of units, and hopefully Commodore can parlay that into more hardware and software support from outside developers, so the Bandito has more neat toys to play widi.

SNAPSHOT Hot Amiga Game reviews by R.B. Andrews Virus First on the list this mondi is Virus, by Rainbird Software. In Virus, you must pilot a hovership in its attempt to fight off wave after wave of different mutating genes direatening die planet. No one knows for sure where these mutants originated from, but you must fight widi all your skill to prevent them from infecting the entire world. As the virus is spread over the terrain, it mutates and becomes lost forever.
The Enemy Fleet: Mutant ships come in several varieties. Seeders simply fly low and spray the virus, landing occasionally to cover an area more thoroughly. A Drone will shoot at botii the hoverplane and the landscape, then attempt to mutate itself by absorbing a healthy tree. This mutated drone will then seek out and attempt to destroy the hoverplane in any way it can, A Bomber flies at high altitudes, dropping large quantities of the virus diat can quickly mutate entire sections of the planet. A Pest’s only goal is to destroy you at all costs, which It can do very effectively. A fighter is
your hoverplane’s, alien counterpart. It will try* to out- dogfight your ship so the overall invasion can proceed.
The last ship is die deadliest of all.
The Attractor has a built-in tractor beam ¦which drains the hoverplane’s energy, causing it to crash. It takes several hits to destroy this menace. Luckily, only a few exist.
Fighting off the invasion would be a totally lost cause except for die fact that a virus-free landscape is generated for the fifth and tenth waves. But this benefit is balanced out by the increase in gravity in waves three, five and seven, making control of the hoverplane even more difficult.
The game features smooth scrolling and solid three-dimensional graphics.
Several added touches, such as the flying fish occasionally seen jumping out of the water as you fly by, spice up gameplay.
The sound is complimentary and up to Amiga standards.
You can use either the keyboard or die mouse to control the hoverplane during flight. However, the keyboard is much easier to use. This brings up the main failure of the game. Learning how to effectively control the hoverplane is a nearly insurmountable task. The mouse moves the plane in unintuitive ways. And flying using die keyboard requires that you access many keys a task difficult for all but the most adept keyboard jockeys.
The game's graphics and sound are almost impressive enough to make Virus a top-notch game. But the difficulty of the game’s controls limits Virus’ potential audience. Those who can master the controls are in for a very enjoyable playing experience. Odiers, like myself and probably 90% of Amiga users are probably not so adept and should limit their enjoyment of the game to watching the demo at die computer store, or watching a friend who can play it effectively.
SpaceCntter In SpaceCutter, also by Rainbird, you have managed to steal a powerful fighter ship from your captors and escape to the Whirligig, an interconnected series of distinct areas called Eigen spaces, Within this network of over four billion spaces lie die five perfect solids. Capturing all five of these will completely free you from your enslavement and return you to Earth's golden era, 1988.
Your ship is a highly maneuverable Meson class fighter. It is equipped with missiles and chaff pod. However, its most important cargo is the fuel it carries. Fuel is used to change your momentum and the speed and direction of your ship. If your fuel supply runs out, you will find yourself drifting forever in the direction you were last heading.
Fortunately, diere are fuel depots throughout the network, to allow for refueling. Also, you begin each game with 12 hulls (lives), so you can switch control to a remaining hull if necessary.
Intelligent Ships: The enemy is a race of intelligent mechanical ships that have enslaved most of the human race.
There are over 100 billion of them in the Whirligig alone, and dieir sole mission is to terminate you. Some are simple passive vehicles that fly along a fixed path, posing danger only in die case of accidental collision. Others appear tame at first, but will fire missiles if your ship passes close enough.
The most dangerous are the ships- of-prey, which wait in fixed locations to ambush your craft, relentlessly dogfight- ing until one of you is destroyed.
Aldiough you can destroy most enemies widi your missiles or chaff pods, some are indestructible. You can only escape them only by traveling dirough one of the many stargates connecting the sectors in the network. As might be expected, the enemies are simple to defeat in the earlier levels. But the higher the sector number, the more dangerous the opponents, until they are nearly unbeatable at die highest levels.
Nothing is left to chance in SpaceCutter. Numerical functions govern everything from the network connecting the Eigen spaces to die location of the supply depots.
SpaceCutter also features sharp three-dimensional graphics. However, travel is only in two dimensions. This may seem limiting, but it works well in practice and is easy to grasp conceptually. The sound is also similar to that in Virus, quite adequate for tire task at hand. Controlling your ship is much easier diough. After a brief pilot training period, most players will find themselves reaching the first perfect solid without too much trouble. But reaching die other four solids will take some time. Only die most dedicated will capture all five and complete the game.
The size of die view' screen can be frustrating even diough it takes up die whole monitor. If you fly at a reasonable speed, enemies can seemingly “jump” onto the screen and kill you before you even have time to react.
Try this game before you buy it. If it appeals to you, it can easily provide many hours of enjoyment.
Operation Cleanstreets Operation Cleanstreets puts you in the role of “Cleanup Harry,'' a tough cop widi a tough mission: Free the city from die stranglehold of five different criminal rings which currently control till aspects of life. Facing one gang at a time, you must free each of nine distinct areas from gang control, and bum any contraband you recover.
Opposing your operation are the many diugs and hoodlems employed by each ring. The first group, the caffeine ring, are relative pushovers. However, the crime rings get progressively harder until you reach the final group, the arcadoine ring, which is nearly impossible to overcome. Some opponenrs are armed with only their fists, while odiers wield clubs or whips. One even carries a samurai sword. Your only weapons are the punches and kicks diat have made your name feared diroughout die ghetto.
Thugs and Drugs: Thugs carry packages of drugs you can recover after you defeat them. You must dien burn diese parcels to remove them from circulation and give your character renewed strength.
You can use either a joystick or the keyboard to control the on-screen character. Both mediods w'ork reasonably well. There is a problem with die responsiveness of die controls at higher levels, though. The opponents get so many opportunities to move that by the dme you attack, the enemy has moved out of range after hitting you several times. This makes play in the upper levels wortliless, and the fifth ring impossible to beat.
Unfortunately, the game’s fine graphics cannot rescue it from its limited dieme. While both the background settings and the on-screen characters are rendered very effectively, the game can quickly become boring, with only nine areas to clean out, and each level simply adding more people and hazards to each of these nine areas. The game could be enjoyable for the right person, but 1 would strongly encourage you to “try before you buy.” World Tour Golf World Tour Golf is Electronic Art’s first entry in this popular area. It has many of the features we have come to (Left) SpaceCutter features
sharp th ree-di m ensionalgraphics (Right) hi Virus, you must pilot a hovership in its attempt to fight off wave after wave of different mutating genes threatening the planet.
Expect in games of diis type. You can play many famous courses, and the game even lets you construct new' courses.
The playing screen features bodi a “birds-eye” view of the hole and a perspective Uiree-dimensional view from your current ball location. The mouse aims and performs the actual shot. The aiming is a bit too course though. There is no wray to make slight adjustments and, often, die default aimpoints are not quite what is needed. It takes four clicks to carry out each swing, and clicks must be performed with careful timing for an optimal shot.
With practice, diis works well with longer shots. How'ever, chipping the bail short distances can be very difficult, since it is extremely hard to make all the necessary clicks at the right times without slicing the ball badly. Keyboard controls are also available to perform “perfect” swings of preset strengths.
The graphics themselves are acceptable. They are crisp and clear but do not really stand out. The sound also compliments the game, with enough noises included to add to die feel of playing on a real course. At die end of each hole, the crowd will cheer if you have done well, and sigh if you bogey (or worse).
World Tour Golf does a reasonable job of portraying the vagaries that face even die most experienced golfer. No (continued) (Left) Iti Operation Cleanstreets, you must free each of nine distinct areas from gang control, and bum any contraband you recover.
(Right) World Tour Golf does a reasonable Job of portraying the vagaries that face even the most experienced golfer.
Matter how good a swing, some shots just won’t go where you plan. Though frustrating, this is a sign of a good simulation and thus a desirable feature.
Custom Courses: The course builder is probably the best part of the game. The player begins by constructing the general layout of the hole. When the player is finished, the computer smooths out this blocky layout and produces a very attractive overhead map. A wide range of pre-drawn trees, sandtraps, and other objects allow even the most unartistic to produce a nice-looking hole.
Unfortunately, when viewed in its entirety, the game falls short of the standards set by other golf games.
Although it is a fine game, it lacks that special feel necessary to make it truly great and worth your hard-earned cash.
• AC- The internal sound capabilities of the Amiga are better
than that of any other personal computer. These capabilities
mean nothing though, without quality digital sounds, which up
till now have been scarce. Sound Oasis gives Amiga owners
access to a large library of studio-tested digital samples, by
using the Amiga’s built in disk drive to read disks made for
the Mirage Digital Sampling Keyboard. Sounds can then be played
from a MIDI keyboard, the computer keyboard, or Saved as an IFF
Standard file. Mirage is a trademark ol Ensoniq Inc. Transform
your Amiga into a professional-quality drum machine with this
software package. Easier to use than hardware-based drum
machines because everything is displayed graphically on screen.
Enter drum patterns quickly and easily in real time with visual
feedback and editing. Create realistic drum tracks with any of
the 100 drum and percussion samples that are included or use
your own unique IFF one- shot samples. Dynamic Drums also has
full MIDI implementation and even becomes velocity sensitive
when triggered from a MIDI keyboard.
A powerful MIDI sequencer that takes full advantage of the Amiga's sound, graphics, and sophisticated user-interface.
Dynamic Studio is perfect for professional applications due to its sophisticated editing capabilities and SMPTE support.
II is also ideal for home studios, because in addition to sequencing MIDI instruments, Dynamic Studio has a built-in drum machine, and the ability to playback instruments translated with Sound Oasis.

Programmer's Lingo!
By Stephen Kemp Computer programmers can be a humorous bunch at least to other programmers. Other people (from other departments) just barely think we're human, much less humorous.
Programmers are referred to as wizards, techno-weenies, and caffeine junkies, but seldom as a fun bunch of interesting people. That's okay, though. Because when a bunch of programmers get together, they can keep each oilier laughing for hours on end with a conversation that wouldn't mean a thing to outsiders. (This would probably be true for a room full of bankers, too, but I'm not talking about them.)
Foreign Languages Of course, a good deal of a programmer’s lingo involves acronyms that have been derived from computer languages or applications that programmers write. Now everybody encounters acronyms in their daily lives. At home there's the TV, VCR, and CD player. Occasionally, we are invited to parties diat are RSVP or BYOB. College students worry about dieir GPAs. And working folks can’t wait to say TGIF. But most likely, nobody encounters acronyms more often than computer programmers.
A typical programmer deals each day with acronyms like PC, DOS, ROM, WORM, BBS, and others. These are fairly basic and universal acronyms, and almost anyone in the computer industry recognizes them. Some acronyms, however, mean more to certain programmers. A word like WYSIWYG (pronounced WIZ-E-WIG and stands for What-You-See-Is-What-You-Get) may not mean a lot to a programmer who specializes in accounting software, but it can represent the ultimate goal for a programmer specializing in word processing software.
Acronyms like these emerge because programmers tend to be cryptic (a side effect of programming). After hearing (or saying) a phrase several hundred (thousand) times, it just seems natural to shorten it down into an acronym. Each one is placed into the computer-lingo dictionary, and usually gets recalled at the most opportune of moments.
At my workplace, we hear phrases that lead to acronyms all die time. Our work not only involves application programming (we developed a 4th generation language and a series of add-on utilities), it sometimes involves some tech support, BBS support and, of course, management confrontations. This has given rise to some new acronyms around our office that you might want to add to your own personal dictionaiy.
YKWWBRN (YUK-WA-BURN) - If you are involved in application programming, you have probably heard this first item without even realizing it. Almost eveiy discussion about the project diat someone is working on begins witli the phrase, “You Know What Would Be Really Nice?” .And is usually followed with the most trivial of drivel you have ever heard.
SIWY (SEE-WEE) - Have you ever worked long and hard on a project, only to see it explode in your face while doing a demo for someone important like your boss?! This is when you say, “S C. It Worked Yesterday!"
WOKOMS (WO-KOMS) - This phrase occurs after you give someone a copy of your product. No sooner do you get settled into your office chair before the intercom buzzes with, “Hey, it doesn't work right!" This is when you reply, “Works OK On My System! You must be doing something wrong!"

hard to deal with a manager or salesperson who keeps wanting a

They always say (with a smile on their face), "This wouldn't be too hard to do, would it?” This is when it is time to reply, “Sign Up For Computer Time.” If it’s not too hard, then they should be able to do it. Don't you think?
Hold The Phone Well, so much for acronyms. They are an integral part of the lives and humor that programmers encounter. Still nothing can beat a good anecdote. With everybody gathered around, programmers can swap stories faster than old ladies at the picket fence. At a place where I once worked, they swore the following story was true.
One day a tech support person received a call from an anxious user. While attempting to calm the customer down, they determined that the user had just installed the product and had now reached an impasse.
“How does the screen look right now?”, asked the tech person.
The user responded, “It says, ‘Press Any Key To Continue'.” “And”, asked die tech person, “what happens after that?” The exasperated reply from the customer was, “I can’t get past this screen! I've looked all over this keyboard, and can't find die Any key!” Then diere’s the user who calls in widi an installation problem... “Yea, uh, I did what the screen said, but things stopped working.” “Okay, let’s backtrack," said the tech. “What happened after you put in disk 1 and pressed the start key?” “Well, it did some stuff and then it said to put disk 2 in Drive A." “Okay, did you do that?"
Inquired die support person.
“Yea. But that's when it quits working. Should I have taken that other disk out first?” This next event was the most recent that tickled our funny bone.
“Hello, Tech Support? I wrote this program that generates a random number that I place into a customer record, and everything worked fine for a while, but now my random number isn't working anymore. Is it possible thaL my computer has run out of random numbers?” Unfortunately, they wouldn't let me call him back to offer him my $ 200 program that 1 just wrote to regenerate the random numbers in his computer.
Working in a Fish Bowl Although we programmers don’t seem to get a lot of respect (or credit) around die workplace, management just loves to show us off to every visitor. Does this Lour package sound familiar?

We give them a special diet of caffeinated drinks and candy bars. They’re in peak condition. Why, diey can solve any problem put to them. Some of them even know a few tricks. Watch this Stephen, speak to the nice person..." Boy! Talk about your fish bowls. Sometimes it makes you want to lunge for their throats. And we would too. Except the leash doesn’t reach the door from where it's attached to the desk. Does this happen to any
of you? Kinda makes you want to pick you nose while they’re watching, doesn't it?
It's a Wonderful Life 1 suppose it doesn’t really bother me what people diink of programmers. 1 do it for the challenge. (I would do it for die money, but there's more challenge than money.) We work in an environment that to most people seems magical, and I love it.
And nodiing gives me greater pleasure dian blurting out a few acronyms in mixed company, or relaying a humorous story that others don't understand. Nothing, diat is, except writing a program, Programming is my life. Programming has been very, very good to me.

• AC* AmigaBASIC Programming Passing Arguments to AmigaBASIC
Programs Pass data from CLI to the BASIC program using script
files and a fvO'lTl th 3 CLI special AmigaBASIC subprogram.
By Brian Zapke The following article is a step-by-step tutorial on how to invoke AmigaBASIC programs from the CLI and pass arguments to them.
In general, most computer programs perform two fundamental functions. They take input data and they provide output data. For example, word processors take input from the keyboard and print out documents. Games read the joystick, mouse, and keyboard (input) and update the screen (output) based on the inputs and the state of the game. These programs take their input data during execution.
In the Amiga Disk Operating System (AmigaDOS) environment, most of the data the DOS programs input comes from the CLI when the programs are executed. For example, the “type” command gets the name of tire file to print and where to print it from the command itself. The command: type readme to prt: causes the file “readme” to be printed on the printer. There is no control information input to the “type" command while executing.
The ability to enter all tire necessary input at a program’s startup time has advantages. You don't have to wait until the program loads to enter the information. A program getting all its data from the command line can be executed without further human intervention. Programs can be invoked from a script or command file, like tire “startup-sequence” file in the “S” directory.
AmigaBASIC programs can be loaded and mn automatically from the CLI by entering the program name after “AmigaBASIC’’. However, there is no built-in way to pass data from CLI to the BASIC program. AmigaBASIC programs must first be loaded and then request the necessary data. This obstacle can be overcome using script files and a special AmigaBASIC subprogram. This method is patterned after the way arguments are passed to “C" programs.
C uses a standard method to pass arguments to programs.
The model below shows a typical format of a C program.
* Typical C Program Format * main I int argc, char *argv(] ) t (statements) ) The two arguments “argc" and “argv” in the above example contain all the arguments entered with the program name on the command line. The variable “argc”, known as the argument count, is equal to the number of arguments entered, including the program name. Therefore, the value of argc will always be at least 1.
The variable “argv1' is known as the argument vector. It is an array of pointers, each pointing to an ASCII string of one of the arguments entered. The element argv[0] will always point to tire string containing tire program name. With these two arguments, the program can determine exactly what was typed in at the command line.
Passing A rguments Arguments can be passed to AmigaBASIC programs using the following method. First, the arguments to be passed to tire BASIC program are stored in a temporary disk file. Second, AmigaBASIC is loaded along with the desired program, and that program is executed. Finally, the program reads the temporary disk file and processes the arguments originally entered. How is tills accomplished? Well, let’s take it one step at a time.
Before you start, prepare a work disk to use for the test script files and programs below. Make sure AmigaBASIC (on the Workbench Extras Disk) is in your work directory or in one of the directories specified by the PATH command. If you do not have a hard disk, I recommend you place AmigaBASIC in the RAM: disk and add RAM: to PATH if it’s not already there. To add RAM:, enter: PATH RAM: add If you do not have enough memory' (AmigaBASIC takes up about 103K), then AmigaBASIC will have to reside on a floppy.
In this case, you will not realize the full benefit of running BASIC programs using this method because of AmigaBASIC’s longer load time. In any case, make sure the work disk directory is tire current directory.
First, we need to get the arguments into a temporary' disk file. For now we’ll create a text file using any text editor but, eventually, this action will be done more efficiently. Once you are in your text editor, type the following text on the very first line: bozo buttons for everyone then save the file as "RAM:test”. This file now contains the arguments our BASIC program will use. Our first program will read the arguments from the temporary file and print them on die screen, Using a text editor or (dare I say) the AmigaBASIC editor, enter the following program and save it as “ReadArgs”.
Be sure to save it to disk and not to RAM:. Files stored in RAM: will be erased when your Amiga crashes or is turned off.

Gg gri Lake Forest Logic Inc. 2S101 £ Bollard Rood leke Forest, II 60045 312)61rH 666 put the argument list there since we really don’t care if we lose it.
V Test program 1 to read arguments and print them out, V OPEN "RAM;test" FOR INPUT AS 1 LINE INPUT !, ArgumentsS CLOSE 1 PRINT "Arguments entered: " PRINT ArgumentsS END The “OPEN” statement allows the program to read in the contents of the file “RAMitest”. The “AS 1” indicates we will reference this file as file number 1. The statement “LINE INPUT" is used instead of “INPUT” to read the file in case die argument list contains commas. If it did, then the “INPUT” statement would split up the line into different fields (the comma separating them) and try to stuff them into different
variables. Since only one variable is specified, only the text up to the first comma would be read in.
Once you’ve saved the program, enter the following line from the CLI: AmigaBASIC ReadArgs This will load AmigaBASIC along with the program you’ve just created. Once the program has loaded, it will RUN automatically. You should see the following in the BASIC window: Arguments entered: bozo buttons for everyone OK Now, exit AmigaBASIC by entering: SYSTEM The next step is creating a script file to create die temporary disk file and load the AmigaBASIC program. Using die CLI “echo” command, we can send a line of text to a file by redirecting the output. Using a text editor, create die
following file and save it as “Bozo”: echo RAM:test "bozos are not bozos without their bozo buttons" AmigaBASIC ReadArgs The “ RAM:test” redirects the output of the echo command (text contained in quotes) to die file “RAM;test”. Remember, by redirecting the output like this, we will destroy file RAM:test if it already exists. If you are using Workbench 1.3 (which you should to take full advantage of this technique), make die file “Bozo” an executable script file by entering: protect Boko s add If you are using Workbench 1.2 (why are you?), forget diis step and use the CLI “execute" command
whenever you want to execute a script file.
Now then, when you type: 3020 (under 1.2, enter “Execute Bozo”) at the CLI, the text “bozos are not bozos without their bozo buttons” will be stored in the file “RAM:test". Following this, AmigaBASIC will be loaded along widi the program ReadArgs.
The ReadArgs program will dien read the file “RAMrtest" and output: Arguments entered: bozos are not bozos without their bozo buttons OK Now enter “SYSTEM” to exit AmigaBASIC.
The next step is to add the ability to enter arguments with die Bozo script command. The script file “.key” statement, placed at the beginning of die script file, allows diis. It specifies the type and number of arguments which can or will be entered. For example, the “.key” statement: .fcsy al,a2,a3,a4,a5,a6,a7,s8 specifies that up to eight optional arguments can be entered after the script name. When the script file is executed, Ainiga- DOS substitutes die arguments in die “.key" statement with the arguments (if any) in die command. This substitution is done on a first come first serve
basis. For example, if a script file containing the above “.key” statement was executed with tiiree arguments, those arguments would be substituted for the first diree keywords (al, a2, and a3) widi the arguments maintaining dieir original order. Change the script file “Bozo” to be: .key al,a2,a3,aA,a5,a6,a7,a8 echo RAM:test " al a2 a3 a4 a5 a6 a7 a8 "
A. 'nigaBASIC ReadArgs Notice there is a space between each
“ a_ ” sequence. The less than (“ “) and greater than (“ ”)
symbols indicate the text they contain (which corresponds to a
keyword in the ".key” statement) is to be replaced with an
argument entered when the script file is executed. If there is
no argument for that label, then tire " a_ ” will replaced
with nothing and only the intervening spaces will remain.
After you save tire file “Bozo”, you might have to set tire
“script” bit again because some editors reset it.
Once it’s saved, from the CLI, enter: Bozo Bozos buy rubber baby buggy bumpers (for 1.2, enter “executeBozo Bozos buy....") When die script file executes, the arguments are inserted into tile “echo” statement of a temporary copy of the script file: echo RAM:"es“ "Bozos buy rubber baby buggy bumpers " the spaces after “bumpers" are die spaces between die a6, a7, and a8 parameters. When the ReadArgs program is run in AmigaBASIC, the lines: Arguments entered: Bozos buy rubber baby buggy bumpers OK will appear. Exit AmigaBASIC and reenter the script command several times using different
As you can see, we can now pass any information to an AmigaBASIC program from die CLI. All we need to do now is have die AmigaBASIC program parse die input line into the individual arguments. I have written a general purpose subprogram to do just that. The subprogram GetArgs.MSB (listing - 1) reads a line from the specified file and separates the arguments using the space as a delimiter. The number of arguments found is returned in the variable "argc", and the arguments themselves are returned in the array argvSO.
To use the subprogram in your own programs, you need to DIMension the argvSO array to accommodate tile maximum possible arguments (detennined by the .key statement in the script file) and specify the name of the temporary file containing the arguments. To see the program in action, first change the “ReadArgs” program to be: DIM argvS(S) CALL GetArgs.MS3( "RAM:test", argc, argvSO ) IF argc ** 0 THEN PRINT "No arguments entered!"
ELSE PRINT "Arguments entered:" FOR x = 1 TO argc PRINT x; argvS (xj NEXT x END IF END Combine the GetArgs.MSB subprogram with it. If you have die BASIC Linker program (published in AC V. 3.10), you can use it to link the files together.

OK Then exit AmigaBASIC.
We are almost through running AmigaBASIC programs from the CLI. All we need to do is automatically return to the CLI (i.e., exit BASIC). Just add the statement "SYSTEM" to your program right before the "END” statement. This works fine and dandy with one exception. All the text output of the program goes to die AmigaBASIC window'. When the “SYSTEM" statement is executed, that window will be closed! With some programs you may not want to see any text output, so the screen closing once the program has completed will not be a problem.
But when you need to see the information, there are two ways of getting around this problem. The simplest way is to add an “INPUT" or "SLEEP” statement before the "SYSTEM" statement or after reporting an error requiring a keyboard or mouse click input before the window is closed.
Anodier way is to use the same method that provided the program with tine arguments from die CLI. Any information which needs to remain after the program exits can be placed into the temporary file using PRINT-’s (after the file has been "OPEN,,ed for "OUTPUT"). The information could dien be

To demonstrate the practical use of passing arguments from CLI and using the GetArgs.MSB subprogram, I have written a simple utility Merge.MSB (listing two) which is similar in function to the AmigaDOS “join” command. The Merge.MSB program is invoked with die script file Merge (listing three).
When bodi files have been saved to disk, remember to set die script bit in the Merge file.
To execute die Merge program, from die CU enter “Merge” with the desired arguments. If you enter “Merge” by itself, you will get a standard format for the command. This is a common practice for commands requiring arguments to execute properly. Also note that if the required "AS" argument is not entered, the program will complain about it.
Being able to pass arguments to AmigaBASIC programs from die CLI opens many doors. Convening C programs to AmigaBASIC will be a little bit easier, and many existing AmigaBASIC programs can be enhanced by adding this technique. A whole class of programs that would have been impractical before can now be written in AmigaBASIC.

This new label represents high arcade quality games, made available at a lower price. Menace is their first arcade “shoot 'em up"-style game, with many more to follow in the footsteps of its release.
After the game has loaded, a title screen will be displayed while a stereo sound track plays in tire background.
Before you begin tire game, you may select one of two different skill levels: normal or expert. Once you have made your choice, game play will begin.
Your Orders: Destry the Planet Draconia You have been recruited to pilot a spaceship to the planet Draconia, and destroy anything threatening to stand in your way. The reason for this destruction is that the aliens inhabiting this planet have destroyed billions to build one tremendous, super planet that is capable of destroying the entire galaxy. The aliens have given this planet the code name Draconia. If Draconia is not destroyed, then trillions of life forms are doomed!
Once game play has begun, you will find your ship’s status indicators located at the bottom of the screen.
Here, along with your score, will be the ship's shield, cannon, and laser indicators showing their current status. Your ship will always be located on the left hand side of the screen, as you pilot your way towards the right.
As your ship glides along, you will notice the background scrolls horizontally with perhaps the best visual effects I’ve seen on a “shoot 'em up"-type game.
One reason for this effect is that the entire game is displayed in overscan mode. This eliminates any borders and provides the piayer with true arcade quality playing.
You will start out at Level One, as the mother ship delivers you close to the planet Draconia. You will quickly notice that action is very intense as wave after alien-packed wave tries to keep you from completing your mission. As you progress through the game, you will encounter over 60 different aliens, each possessing powers deadly to your ship’s defenses. In order to destroy the aliens, your ship is provided with a lower power laser. Some aliens can be destroyed with tire laser after several hits, while others are impossible to destroy widrout more firepow’er.
If you choose, you can navigate through some of the aliens. However, any contact made between the aliens and your ship wall result in your shield power being reduced. Also, on tire more advanced levels you will find that some aliens are equipped with heavy firepower, which makes game play even more difficult. So, in order to have a fighting chance, you will be rewarded for destroying all aliens within a certain wave.
Bonus Power After all aliens have been destroyed, a bonus icon will appear in the posifion of the last alien, and it will begin to approach your ship. You will be rew-arded with whatever value this icon represents. You may shoot the icon five times, wiiich will result in one of the following: 1000 bonus points, laser cannons, long-range lasers, increase in your ship’s speed, outrider being attached to your ship, force field, or shield regeneration. Whenever you fly over one of these bonus items, it will automatically be engaged, that's One Tough Mother Alien.1 Menace contains six complex
levels, each more difficult than tire last.
In order to advance to the next level, you must first destroy the mother alien who waits for you at the end of each round. Each of the mother aliens you encounter will be much tougher than any alien you might have faced during that level of play. To destroy tire mother alien, you will have to shoot it many times. You will need extremely fast reflexes to dodge the mother alien’s devestating onslaught.
Saying Goodbye to Draconia Game play will end when you have either destroyed die entire planet of Draconia, or you have used up all your ship's shield power. If you have been killed, you will be given the option of restarting tire game on the same level on which you were destroyed. However, when this happens you will loose all other increased firepower which you might have added to your ship, not to mention your score. Oh well, you can’t win them all!
Summary Menace is perhaps one of tire best games ever released from Psygnosis Software. The manual included with tire game explains all the bonus items and their functions, along with other important information about the game. During game play you will use the following options: pause game play; toggle sound effects off on; toggle music off on; and abort game play, which takes you back to the title screen. Menace combines great sound effects, graphics, music, and visual effects for w-hat is certain to be a hit with all the arcade addicts out there!
Hints and Tips Whenever possible, try to shoot all the aliens in tire current wave for a bonus icon. Once tire icon appears, start shooting at it until you have managed to get either the cannons or lasers. You will definitely need one of these weapons in order to survive tire end of each level with the mother alien.
If your shields are weak, you may avoid some of the aliens by flying around them. To do this, simply select a spot on the screen where the aliens are not concentrated (most likely towards the bottom), and fly right past them.
While this is not tire best way to score, you will be able to progress further through tire game.
Be sure to avoid using the force field w'hen you are between alien waves.
This will give you more time for protection against tire aliens’ attack.

Amiga System Programming Creating Shared Libraries by John Baez Why Shared Libraries?
One of the most powerful features of die Amiga's operating system is the ability to use general purpose functions stored in special programs called libraries. The advantage of diese shared libraries, as diey are called, is that one copy serves as many programs as necessary, and almost every programming language on the Amiga has some way of using them.
In a complex environment such as diat of die Amiga, libraries provide a means for accessing even the most complex facilities in a straightforward manner. A clear example of die power of libraries is demonstrated in the Amiga’s standard libraries. These libraries make it possible to access all of die Amiga’s features without having to worry about the details of die functions. (Imagine what a routine that moves a window over the workbench screen without erasing any icons is like!)
Standard routines like IFF functions should be placed in libraries so any Amiga programmer can access them. Right?
Right! So how come we hardly ever see general purpose functions implemented as shared libraries? I found the answer to this question when I set out to create a library for my own use.
Anyone who tries to create a shared library immediately runs into two problems. The first problem is a lack of documentation. Reading the RKM and studying its examples is like reading German and trying to interpret it as Spanish. The second problem is that some knowledge of 68000 assembler is required. Most programmers end up taking die easy way out by creating a link library (for use with alink or blink) which can only be accessed by a limited number of languages.
I’d like to take some of the mystery out of creating shared libraries in the hope that more programmers will create them.
This is the best way to provide general usage functions across the broadest number of Amiga programming languages (and Amiga programmers). This applies to casual program mers as well as professional developers. Making powerful facilities available to die Amiga community is a great way to enhance overall productivity. Shared libraries can go a long way in accomplishing this.
Base -N*6 Base -12- Base -6 The Structure and use of a Shared Library An Amiga shared library' is a very' simple structure once loaded into RAM. It consists of some basic information such as how many tasks are currendy using it and a table of die addresses of the functions which make it up, as shown in figure one.
Library base address Whenever a program wishes to use one of the library’s functions, it just gets that function's address from die library’s address table and jumps to that address, All it must know is the table's location and which addresses in the table correspond to die desired function.
If you look at the library structure in figure one, you’ll notice diat the function addresses are located in reverse order above what is called the library base address. (The first function is closest to die library base.) The library base address is die address table location, as well as the point where die library's basic information starts. Therefore table entries are lower (negative) than the library' base address. Library information is higher (positive) titan the library base address.
Each entry in die function address table has a lengdi of 6 bytes. Therefore, the first function of the library is located at library' base -6, the second is at library base -12, etc. The (-6) is called the library' offset.
If we use our newly learned terminology we can say diat in order for a program to access a library function, it must know die library base and the library' offset for the desired function.
Each particular language lias its way of obtaining this information. The programmer doesn’t require the library' offsets in order to access library functions.
In AmigaBASIC, for example, the programmer only needs to make sure that die ‘.bmap’ file(s) for die library(s) he is going to use are in an accessible directory. The ’.bmap’ file, as we will see later, contains die library offset for each function of a particular library'. This is how BASIC knows where the library functions are.

Creating a Shared. Library Now that we understand the mechanics of shared libraries, let's see how we go about creating one.
A shared library looks like a regular program to AmigaDOS. It can be loaded and executed just like a program. And it is created just like a program. (Well, almost.) What makes a library' distinct is that it must have a particular structure. This structure (a pattern) is searched for by Exec when the library is loaded into memory widi an OpenLibraryO request. If it isn’t found Exec unloads the code and OpenLibraryO returns a zero.
If it is found then another series of events takes place based on information you supply as part of that structure.
If you look at listing 1 (the assembly listing) on lines 29 through 38, you’ll see the structure we’re talking about. The first 2 bytes are defined as $ 4AFC followed by the address of their locadon. This is called a romtag and is the identifier that Exec looks for when it loads the code as a library.
The next long word (line 31) contains die address of the end of this code segment. I'm not sure dris really matters as I've seen libraries where this points at different iocadons.
The byte defined at line 32 tells Exec what kind of init we are. A value of zero (0) says we are not auto init. Before we go any further let me explain the differences between auto init and us (self init?).
When auto init is requested, Exec makes a call to MakeLi- braryO which allocates storage and creates our library base. In this case we would not be required to define and initialize our library,'' as we do in lines 49 to 83. MakeLibraryO would do this for us. We would have to supply a list of function addresses and an initialization block. We would not be required to call AddLibrary (as we do at initialization) . Tills is the way the RKM example illustrates.
There are two reasons why I don’t use auto init. Using auto init has execution overhead (nothing significant). It also uses more storage since it requires the definition of an init block and duplicates die function addresses. Neither of these issues are powerful enough to justify' not using auto init. But die small savings in space justifies not using it for me.
The next 2 bytes (lines 33, 34) represent the version (1) and die type (iibrary=9) of romtag that we are (we could have been a device!).
The next byte (line 35) is the priority©) followed by a pointer to the library name and a pointer to the library id string.
Last Qine 38) is a pointer to the initialization routine which will be run when our library is first Loaded. If we had been auto init, then this location would have pointed to an initialization block instead.
Our library is defined in lines 49 to 83. The first filing we see is the function address table (jump vector) in lines 49-64. As mentioned earlier, each entry uses 6 bytes and the functions are listed in reverse order. Note that die functions closest to the library base (which is at line 69) are documented as system support functions. We’ll be looking at each of diese to see what they do, in a moment. The fifth entry from the base is our first function (library' offset=-30). Our sample library has only two functions.
The first two bytes of each entry represent a machine language jump to a long address (The assembler I used wouldn’t generate the right code for ‘jmp.l’ so I hard coded it in hex). The following 4 bytes contain the address of the machine language portion of our funcdon.
Following die jump vector is die library structure. This consists of an Exec node structure followed by 20 bytes of library info. Lines 70-73 initialize the node.
Line 74 initializes the library' flags. Our initialization says that we require check sum checking and that we need the check sum to be calculated. The best explanation of these flags that I have seen is on page 152 of Sybex’s Amiga Programmer's handbook.
Line 76 indicates die size of our jump vector in bytes. We have 6 entries at 6 bytes each. The next word represents data size. This includes the library structure (34 bytes) plus any data diat we define. In this case we are using one long word (4 bytes). This totals 38 plus two bytes I added for psychological security.
That constitutes the data portion of our Library. We must now define our library routines. In order to do this we must keep in mind that Exec passes us information in registers. That is why diese routines are in assembly. Once we place the arguments on die stack (where C expects them), we can call the C funcdon. That is basically all these routines do (the assembly routines, diat is) and that is why creating a library requires some assembly language.
The assembly routines are simple, straightforward and documented on the listing itself. You shouldn't have to change them for anything. Note diat in the call to the C functions, the function name is preceeded with an underscore. That is the way C generates the function name internally, so all assembly references to C functions (and names) should be preceeded by an underscore.
The important point in the assembly routines is the placement of registers on die stack. This is done widi the ‘movem.r instruction you see prior to each 'jsr' to C. It is important to note diat die registers are loaded on the stack starting from A7 to AO and D7 to DO. This means diat you must assign registers to your arguments in that same order. If your funcuon uses 4 arguments, for example, you could assign registers DO through D3 to arguments 1 to 4 respectively. You couldn’t, however, do it backwards or assign a random set of registers such as DO, AO, D'l, Al. If you have doubts, you may
use die ‘moved ir,-(sp)’ instrucdon to place one register at a time on die stack.
The C funcdons should look pretty familiar. You can modify them as indicated in the source listing. You may open odier libraries, call other functions and do anything you need.
Be aware that you are coding functions which may be used simultaneously by various processes. Therefore, be careful not to code anything which will mess up by reentry. In particular be careful about using static variables.
Assembling, Compiling, and Linking Once you’ve created your library source, proceed as follows: asm slibh.a -rmr -nl let -bO -cemsw slib ic2 -rO -v -sc=teat -sd=text slib blink slibh.o+slib.o to slib,library lib lib:lc.lib+lib:amiga.lib SC SD ND The assembler used is Wesley Howe’s asm68k which is in PD (I couldn't get the lattice assembler to work properly and their scarce documentation didn't help much so 1 dumped it).
Once you’ve linked your library, you should copy it to your LIBS: directory before doing any tests.
Gaining Access to Your Library Once your library has been created, you’ll need to provide the means for external programs to access it. As we mentioned earlier, different languages have different ways of doing this.
Instead of trying to access it from one or two places, we'll use the method provided by Commodore to provide the required information to whoever needs it.
Commodore has provided a file format which describes shared libraries so that anyone interested could read the file and obtain the required library offsets. This format, commonly knowm as the ‘id’ format, can usually be converted to the format required by different languages via conversion utilities.
We’ll see a few examples of this later. Let us take a look into the fd file required to access our sample library.
Listing 3 shows what tire sample fd file looks like. The first line identifies the name of die library base. In this case it is named _Siib. The second line contains the starting offset of our Ameristar Internet Package Connect the Commodore-Amiga computer to TCP IP based ethernet networks with Ameristars integrated hardware software solution.

_LibraryHame ;LI3F CHANGED|LIBF SUMUSED functions. Since our
first function is the fifth one in the library's jump vector,
we use a 30 (5 times 6 bytes per entry).
As long as you use the library structure as we’ve defined it, the first three lines of your fd file will always be the same except for the name of the library' base. These are followed by the function definitions in their proper order.
Each function definition has the function prototype in C format followed by the registers in which die arguments are passed between parenthesis. You may use registers D0-D7 and A0-A3 to pass arguments in relative safety (this applies to Lattice C users only). Make sure your registers correspond widi those placed on the stack on the call to C from assembly.
Once you’ve created your fd file and saved it (usually as ‘libname.fd’), you can then use your language’s conversion utility to create whatever your language requires. In AmigaBASIC, for example, you run die convertFD program and it will create the required ’.bmap’ file. For Lattice C you run FD2PRAGMA and it will create the appropriate -pragma header file. Listing 5 shows the -pragma statements generated for our sample library.
A note on pragma. The current implementation of libcall limits functions to 4 arguments (they don’t mention this in die manual). I don’t know why Lattice did this (it ruins an otherwise great feature). Until the limitation is removed keep diis in mind if you’re designing functions for use by Lattice C. Some languages (Lattice & MANX C and Modula 2, for example) use stub libraries which they link to at mn time. The stub functions are small assembly routines which have the library offset hardcoded into them. They use it to perform a jump to die appropriate location from the library base. An
example of stub functions for our sample library' is included in listing 4.
After you’ve done your fd conversion, dien you just proceed as you do with any other library. Listings 5 and 6 illustrate diis for AmigaBASIC and C using our sample library.
Step by Step Review Let us go over die complete process step by step. Once you've entered listings 1 and 2 and you’re ready to create your owm library, proceed as follow :
1. Modify the assembly program jump vector (lines 51-
54) to include your functions
2. Adjust the jump vector size (line 77) accordingly
3. Add the appropriate XREF(s) at Lines 18-19
4. Modify lines 40-41 with your library info
5. Copy one of the routines in lines 159-169 and modify7 the
movem.l instruction to include die appropriate registers. Do
this for each function you’re adding to the library
6. Add your C function to the C source
7. If required modify7 the C source initialization, open, close
and expunge routines to accomodate any special needs your
library7 may have (optional)
8. Assemble, compile and link your library
9. Place your library in the LIBS: directory
10. Create an ’.fd’ file for your library7
11. Convert your ‘.fd’ file for the language you use
12. Test your library slibh.a - shared library assembly header

A few pointers:
- be consistent in the way you pass arguments. Remember that each
arg requires a register in the assembly counterpart. Hake sure
you save any registers other than AO|Al,DO,Dl that you may use.
Never use A5 or A7, If you have global variables declared in your C code you shouldn't use A4.
- be carefull about declaring static data inside your functions.
As a library you may be used by various tasks simultaneously.
This may cause static values to get messed up.
- library functions should do general purpose things. If it can't
be shared by other tasks its usually not worth placing in a

• AC- If you've been around computers long enough, you have
inevitably come across the concept of sorting. Sorting is the
act of organizing data in some determined order. This is
usually done so the data can be accessed in a quick and
efficient manner. An example of sorted data is a phone book:
the data (names, addresses and phone numbers) is sorted in
alphabetical order by last name. In computerese, we say the
last name Is die sort key.
There are many methods of sorting data, some better than odiers. A large part of computer science literature is dedicated to analyzing die various sorting algorithms. The trouble with this approach is, while the sort algorithm is described mathematically and precisely, most people have difficulty visualizing, and completely grasping, the sorting process itself.
1 hereby present a program, called MultiSort, which graphically illustrates a few of the more popular sorting techniques. The program is educational in more ways dian one.
Aside from visualizing sorting, it also demonstrates the power and ease of using multi-tasking on die Amiga.
Using MultiSort MultiSort opens a hi-res interlace screen and four windows, one for each sort that will be used. Data is represented in each window as a pixel plotted for every element of an array of numbers. The pixel's x coordinate is the array' element number, while the y coordinate is die element’s value. For example, if die second element in die array has die value of 21, then its corresponding pixel will be plotted at coordinates (2,21). The origin (0,0) is at die upper left comer of each window. Therefore, a sorted array widi no two elements having the same value will be represented
as a diagonal line drawn from the upper left corner to the bottom right comer.
Upon startup, the array to be sorted will contain random data, with no tw'o elements having the same value. I call diis uniquely random data to distinguish it from simple random data, in which two elements of the array may contain the same value. When the unique random data is sorted, a straight diagonal line will be displayed.
Data organization can be specified through die “Data” menu item. The following choices are available:
• Ascending The array will be presorted in ascending order. Each
element’s value will be the element's number. For example,
the third element will have die value of 3- The data will be
displayed as a straight diagonal line from the upper left comer
to die bottom right comer.
• Descending Similar to die ascending option, only die array will
be sorted in reverse order. The displayed data will be a
diagonal line from the bottom left comer to the upper right
• Random The array will contain random data. More dian one
element may have a specific value.
• Unique Random The array will contain unique random data, as
mendoned above.
• Customized You can enter die data manually. Choosing diis opdon
will open a data entry window. Simply click in diat window and
draw your data in. When done, click on the window’s close
gadget and your customized data will be copied into all the
Sordng may be initiated through die “Start” menu item.
While sorting is under way, the menu will provide a “Stop” opdon. Currendv, only the Bubble sort will require die stop request. I felt that since the other sorts were fast enough, it was not necessary to slow them down by having diem check die menu requests. Since the Bubble sort is extremely slow', it w'as the only one that merited die stop capability.
(continued) Once die sort is completed, each window's title wiil display the corresponding sort’s piace on the finish line. Three asterisks mean that a stop was requested before that sort was done.
MultiSort is most useful for comparing various sorts side by side. However, you may at times want to use only one sort on a larger array. This is provided dirough the Zoom menu.
Through zooming you can observe one of the selected sorts on a larger array (and larger window).
Hoiu it Works When executed, die main process begins by setting up a few diings. Such as opening an Intuition screen, and opening windows - one per sort. The last part of setting up is the creation of sub-tasks, one for each sort. It then loops, waiting for menu selections.
Multiple Windows with One IDCMP Port Usually, when an Intuition window is opened, Intuition allocates for it a message port known as the IDCMP port, through which it communicates various Intuition-related messages.
Since all die windows should display die same menu, and all are monitored by die same program, it is not necessary to let Intuition create a separate IDCMP port for every window, The program makes sure that only one port is created, by allocating one itself and by forcing Intuition to NOT create an IDCMP message port. This is done by setting up die IDCMPFiags field to null. Once die window is opened, its UserPort pointer is pointed to the allocated port, and die proper IDCMPFiags are set via a call to ModifylDCMP.
Closing windows that share the same port requires the reverse of the above procedure. First, all pending Intuition messages must be removed from die port (or else some adverse diings can happen). Then the window’s UserPort must be sent to NIL, as well as to the IDCMPFiags field. Only then can CloseWindow be called.
Task Creation The parent task creates sub-tasks with a call to CreateTask.
The parameters to CreateTask are: new task’s name, the created task's priority, die address of die code die created task is to execute, and the size of the task’s stack.
The sub-task's local variables are allocated on its own stack space, so make sure the stack is large enough to accommodate all local variables, as well as anything diat may get pushed onto the stack during procedure calls (i.e. return addresses, and the called procedures’ local variables) or during a context switch (when the system switches to anodier task it pushes all the CPU’s register on the stack).
Reentrancy and Multitasking Naturally, die sub-tasks can freely modify their own local variables, but they can also access the program’s global variables. Modifying global data is a tricky chore with multitasking.
Therefore, it should eidier be eliminated or done in a restricted, well understood manner. This is necessary because all die subtasks execute the same code and, as such, should not change any data that might accidentally affect each other. This ability to execute the same piece of code by different tasks, without adverse effects, is calied reentrancy, and it is an important concept in multitasking operating systems.
In MultiSort, the only global variable diat may be changed by the sub-tasks is GlobalCount. Whenever a task is about to change GlobalCount, it issues a “Forbid" which disables execution of all other tasks until a “Permit" is issued. This prevents any problem of concurrent access to GlobalCount.
Signals for Intertask Communication The parent task sends instructions to the sort sub-tasks, and waits for a response from them. In a previous article, I described intertask communication using messages and ports, hut those are not employed in MultiSort; instead, only signals are used. The RKM defines a signal as an “event indicator”. This is the basic mechanism used for all intertask communication.
The message system, in reality, uses signals to notify tasks of die arrival of new messages.
A task may define up to 32 different signals, 16 of which are reserved for system use (leaving 16 user signals). These signals are represented as bits. They are independent of each odier, and may be used concurrendy. A signal is relative to the task that defined it. Any task wishing to signal a target task must use a signal that was defined by the target task.
A signal is defined using the AilocSignal roudne, which returns the allocated signal bit number. A specific signal can be allocated by passing its number to AilocSignal, or -1 can be passed, to let die system allocate die next available signal.
Before diis signal can be used in any signal related routines, it must be converted into a bit mask. In C, that would be done with the shift operator («), but in Modula-2 that is done by INCLuding it in a bitset, as follows (using Benchmark): VAR SigBItNum : SignalRange; SigMask : SicnalSet; BEGIN SigBitNum := AilocSignal(AnySignal); INCL(SigMask,CARDINAL(SigBitNura); Signalling a task is done dirough a call to Signal, which accepts to argument: a pointer to the target task, and a signal mask containing the signal bit that was previously allocated by the target task.
.Sorts I’ve included modules for die following sorts: Bubble, Quick, Shell, and Heap. These are probably the most widely known sorts. I've extracted the implementations from various sources, and modified them in only two ways. First, whenever an element of the array changes in value, a call is made to UpdateDisplay. Second, where some implementations assumed that arrays are 1 relative (i.e. the first element has an offset of
1) , some additional (but trivial) changes were introduced to
handle die fact diat Modula's open arrays are 0 relative.
Program Modules Aside from the four sort modules, the program consists of die following modules: Termination The code for this module appeared in a previous article.

By DougMcdonald, Amiga port by Eric Kennedy Fred Fish Disk 185 Commodore IFF This is a copy of the
official November 1988 Commodore IFF disk. All the files in die “documents" directory are in zoo file “documents, zoo" (continued) IntuiCommon A collection of various Intuition-related handy routines.
MSGlobal Declaration of global constants, type, and variables.
MSMisc Miscellaneous routines.
MSMenus Code to set up the menus.
MSData Handies the collection of the array’s data.
MSZoom Routines used for the zooming feature.
MSSortTask Contains the sub-tasks' main routine.
MultiSort The main module.
The code was written in such a way that adding new sorts is trivial. Simply code the sort (with a procedure declaration that will match the ones for die existing sorts) in its own module, making sure that UpdateDisplay is called after every code statement that might alter die value of an array element. Then add a statement to the initialization section of module MSGLo- bal, calling AddAsort with the appropriate arguments.
Caveat Because one sort completes before the otiiers does not neccesarily mean that it is better than die rest. It only means that this particular implementation sorted the particular data faster than the other sorts. If you try different implementations of the same sort (there can be some variations on die same theme; the books mentioned below had quite different implementations), you might find diat their performance varies greatly.
Suggested Readings If you’re interested in further reading on sorting, here are some books that will send you in the right direction; Algorithms and Data Structures by N. Wirth Prentice-Hall.
Data structure using Pascal by Tenenbaum & Augenstcin Prentice-Hall.
