      The original Macintosh did not have preemptive multitasking. It also came with a monochrome screen. Its 3 1/2" floppies were single-sided 400KB while the Amigas were double-sided 880KB.

      As for the 16-bit color, I find that somewhat hard to believe without a daughterboard and new graphics chips. If the claim is correct, the Mindset had a 512 color (9-bit) palette. No amount of video memory would give you 65536 (16-bit) colors. Unless it had another palette mode which seems unlikely.

      I have heard of personal computers with better graphics and sound than the Amiga, but they are all posterior to the 1985 A1000 launch. Examples include the 1987 Acorn Archimedes which had a 32-bit CPU and better graphics or the 1989 Fujitsu FM Towns on which you could have 8-bit colors from a 15-bit palette.

Apple survived by going into DTP and graphics, and Commodore tried video editing -- but for the most part Commodore was stuck trying to keep an entirely custom software/hardware platform alive by selling incredibly cheap machines to the video game crowd.

They had some great developers, but more often than not, it seemed they were thwarted by bad business processes and/or decision makers up top.

      It was the particular hardware design of the Amiga that positioned it for the application area it ended up dominating for a time. However, it was much more the efforts of third party hardware and software vendors that kept Amigas relevant.

      Newtek, Great Valley Products, Scala, the developers of Imagine, Real3d, and all the various genlock manufacturers to name a few.

      Without these companies, things would never have gotten off the ground. You know you're failing to meet demands as a computer manufacturer when the standard route to a high end system was to buy a 16bit machine and virtually superceed its entire internal hardware with expansion cards.

      In the case of the Amiga, for much longer than it should have been, you bought an A2000 which came with a 16bit CPU, space for 8MB of 16bit memory, at best 4096 colours (a bit of a hack) and a SCSI controller. You would immediately buy an expansion card containing a 32bit CPU/FPU (ya you youngins who take their FPU so much for granted its not mentioned in separation from the integer part of the core these days), space for 8MB of 32bit memory and a faster SCSI controller from GVP and some sort of 24bit frame buffer. A couple years later the framebuffer was bumped for a Newtek Video Toaster.

      The Amiga itself became increasingly subordinate, and when the A3000 came out it was a bit too little too late. The A4000 release date was just pointless.

      The whole collection of components was called Kickstart (because it was the low level OS) and the GUI interface component was called the Workbench.

      the Amiga OS was largely written from scratch with the exception of the AmigaDOS component (Filesystem/Disk manager) which was written in BCPL based on a legacy DOS that was available. AmigaDOS was a last minute addition which is why it wasn't written from scratch.

      The OS was the first desktop computer to use a microkernel approach where all the components of the OS were independent objects which communicated via message passing. It also was the first desktop OS to provide pre-emptive multi-tasking but because it didn't have a "smart" scheduler, the system could still be brought to its knees with busy-loops.

      There were many features that made the Amiga's OS a joy. The filesystem layout of a separate library (equiv of DLLs) and font directories made keeping your installation clean a breeze. In fact, in Kickstart/Workbench 2.0 and up, you could do the UNIX trick of specifying an environment variable for your library and font paths so you could have MULTIPLE library and font directories. In fact, the Amiga environment variable system was implemented as a RAM drive so it could have directory structures. Fond memories of setenv "SASC/scoptions" -g.

      Device I/O was asynchronous. You passed and received messages to the hardware while your code could go off and do other things. Where this really made a difference was in the Sound device which allowed some fairly inventive sound mixing to go on because while the sound device went off to play your sample, you could mix up the next sample for it to play. In the mid-80s, no one was doing that on a desktop/home PC.

      The GUI library, called Intuition, had a nice clean design. Things were properly partitioned into their own libraries/modules and the API was clean and easy to learn. The designer of Intuition said his only regret was he couldn't make it into a pure device for completely asynchronous operation.

      The message scheme of the Amiga is still, IMHO, the best there ever was. Based on what amounted to a primitive C-based version of classes, you allocated a structure for your message, filled out the required fields and sent it to a Message Port. You could wait around for a response, or do other things while periodically checking on the message port. This made creating event driven code a dream. With one function call, I could watch a dozen MessagePorts (or just one, actually -- a MessagePort could receive any message). With that one call, I can listen for:

      • Input events
      • Sound device responses
      • TCP/IP connection requests or data received
      • Messages from other processes
      • AREXX messages

      Trying to do the same thing in Windows was a severe pain until very recently, and even now, it's still a pain.

      The Amiga had its flaws. For example, by chosing the cheaper 680x0 processors, the Amiga never had memory protection or virtual memory which made for some fun crashes. The memory allocation code was such a piece of crap that if you weren't careful, you could fragment all of the system memory and even other applications would be affected (see the no memory protection or virtual memory flaw). Also as mentioned, the pre-emptive schedule did not adapt to "bad" programs such as programs doing busy loops.

      All in all, it was still a dream. I still miss programming it. The NeXTStep OS is the closest I've ever seen any other OS get to it.

      Kickstart was (usually) in ROM and contained the low-level stuff. Workbench was loaded from floppy or HD and contained the GUI, extra libraries and other stuff.

      Actually, I'm not sure whether 'Workbench' was the GUI only or not - the 'Workbench' floppies did contain more than the GUI but when one said 'Workbench' one usually meant the GUI.

      the Amiga OS was largely written from scratch with the exception of the AmigaDOS component (Filesystem/Disk manager) which was written in BCPL based on a legacy DOS that was available. AmigaDOS was a last minute addition which is why it wasn't written from scratch.

      The DOS component of AmigaOS (CAOS) was lagging behind the rest of the system, so instead of delaying the introduction of Amiga 1000 to get it finished an outside contractor was signed on to port an existing DOS to AmigaOS. Which is why AmigaDOS has some oddities, like BCPL.

      About CAOS

      but because it didn't have a "smart" scheduler, the system could still be brought to its knees with busy-loops.

      The scheduler was a simple priority round-robin algorithm, meaning that the highest priority runnable task would get the CPU. If there were several runnable tasks at that priority level, the scheduler would round robin between them.

      The OS kernel ran at the highest priority, GUI and device drivers a bit lower, user programs at 0 and background tasks below that.

      As you mention, the obvious problem was that a busy-looping task at a priority higher than user programs would completely starve them for CPU, effectively locking up the system from the user's point of view.

      It did have its perks, tho. Since the GUI was running at high priority it instantly got CPU so the system felt very responsive even when heavily loaded. It was also simple to start a long running task at a lower priority than normal user programs and have it churn on something in the background with close to no impact on system and user program responsiveness - back in those days the ability to have a big compile or render running in the background and hardly noticing it while typing in your editor was mindblowing. ..but a single program busy-looping at a priority higher than normal user programs, and it was three finger salute time.

In fact, the Amiga environment variable system was implemented as a RAM drive so it could have directory structures. Fond memories of setenv "SASC/scoptions" -g.

      Paths, Labels and env are separate.

      The path is where the shell would look for executables. Works just like in Win or *nix.

      Environment variables also work like in Win or *nix, except that they were stored and could be accessed as a RAM file system.

      Labels, though, is very nifty and very Amiga. Those familiar with MS-DOS can think of them as drive letters on steroids.

      Labels could point to a device (DF0:), volume label (WORKBENCH:, GAMEFLOPPY:), pseudo device (SPEECH:), or they could be assigned to a directory.

      AmigaOS came with a set of default device labels. DF0: for first floppy, DH0: for first harddrive. The system would look for libraries in LIBS:, fonts in FONTS:, etc. Every floppy and HD had a volume label, so if you had a floppy named games you could access it with GAMES:. If GAMES: could not be found, AmigaOS would prompt you to insert the floppy. In addition you had special labels like SPEECH: which sent any files copied to it through a speech synthesizer.

    In looking back, it is amazing the number of things they absolutely nailed wih the Amiga. It was the first machine to use fully-programmable custom chips for sound and graphics support. That hardware was immensely powerful; it could do memory copies (the blitter), palette shifts (the "copper", and I don't remember why it was called that anymore), sprites, collision detection, four-channel stereo sound, and probably many other things I'm forgetting, without even using the main CPU at all. (well, except to set things up, at any rate.)

    The system could display separate programs with separate resolutions and color palettes on the same screen at the same time. You could literally grab the Workbench screen and drag it down, revealing some cool demo running behind it..."Boing!" in the top half, Workbench in the bottom. This was done by some clever copper tricks... on the fly, over the space of about two scanlines, the copper would shift the entire display mode and palette, and start displaying screen data from a different arbitrary program.

    Later, a variant on this technique was used to create the best graphics the Amiga could manage...Sliced HAM, or S-HAM. The default 'high color' graphics mode, HAM, could have any 32 base colors out of the palette of 4,096. Any pixel could either have one of the base colors, or it could H)old the color of the previous pixel A)nd M)odify either the red, green, or blue component. S-HAM took this a step further, and swapped the base 32 colors on *every scan line*, so that you could have many more colors available. Some of the S-HAM pictures were absolutely stunning. It did, however, put a huge load on the graphics hardware... the machine really crawled when running that mode. So it was really only useful for slideshows... you couldn't animate that mode, to my knowledge.

    Then, on top of that, they mostly nailed the OS. There were three major components to the AmigaOS; Exec, Intuition, and AmigaDOS.

    Exec was the multitasking core, what we'd probably think of as the kernel in Linux land. It was immensely efficient. The task switching method that RJ Mical came up with was so fast that it ended up going into the Motorola programming manuals. I can't find the numbers offhand, but I believe the Amiga could task switch in less than twenty clock cycles. Whatever the actual number was, it was FAST.

    Intuition provided the windowing libraries; it was what kept windows properly layered and coordinated, and routed user input. That would be roughly the equivalent of X, though much simpler. Workbench, the built-in graphic UI, was an optional load; you could stay in 'console mode' if you wished. The Amiga had no true text-only mode, however. Even if you had just a single CLI window open with nothing else, it was still drawn in graphics mode. (scrolling on the Amiga was never very fast because of this).

    AmigaDOS, I believe, did all the disk and file I/O. It was rather Unixish, but it was very slow and had an absolutely horrible user interface. (Fortunately, it was easy to replace the DOS programs with better ones, and most people who really used their machines did so.) Filesystems were abstracted too, which was a good thing.... the early filesystem on the Amiga was very fragile and very slow. Later on, the Fast File System was introduced, which sped things up a heck of a lot. With FFS, hard drives were quite comfortable, but floppies were never very good. There were many special custom loaders that sped things up (much like on the C64), but the floppies were always slow, no matter what.

    Of the three major components of the OS, AmigaDOS was the weakest, and was responsible for a lot of the early (justified) griping about the pl

  21. I have very fond memories of the Amiga by sgant · · Score: 4, Interesting

    Had a friend that I met through the Amiga that developed Disk Mechanic for the Amiga. Eric Quackenbush. He was independent before he went to Greater Valley Products to develop for them. He was a HELL of a programmer. Last I heard he was doing things for OS/2 but this had to be 10 years ago.

    I remember I had lured some guys from Pixar to a Chicago Amigafest to see if they wanted to port Renderman to the Amiga. The Amigafests were small affairs compared to the Apple or Microsoft ones back then, but I got a guy to fly out to it. He was nice and everything, but you could tell he thought it was kinda small-time. He was polite and suggested that we just make a Renderman compliant renderer for the Amiga. And looking back he was right, the Amiga just didn't have the horsepower to run Renderman at the time.

    This was when Alan Hastings had just come out with Lightwave for NewTek...having hired Alan after his Videoscape 3D was a semi hit. Videoscape had competition from Sculpt-Animate 4D and Turbo-Silver 3D. But it was Lightwave that really broke through. This was in the days when it was a single guy doing all the programming/developing for the product. Remember them? Alan had very little help when developing Videoscape and I believe he had a partner join him in making the first version of Lightwave. Newtek was the center of the Amiga universe at the show with the VideoToaster and Lightwave.

    I miss that really. It was a small group of very rabid fans that loved this machine. I used to go to Amiga user group meetings and met a lot of really friendly people. But all good things come to an end. I just wished the Amiga had a more dignified death.
