The Almost Forgotten Story of the Amiga 2000

polyp2000 writes Many don't realize the impact the much forgotten Amiga 2000 had on the world. This lovely article is an informative and lighthearted read, especially if you are interested in the world of CG. "Unfortunately, The Amiga 2000 is one of the least favorite or collectible Amigas. Even today, with the most "die hard" Amiga fans, the A2000 often is ignored and shunned as a 'big, ugly' tank of a machine. One look at eBay (Canada or the U.S.), on any given day, and you can see that the A2000 often doesn't sell at all, and most times goes for a lot cheaper than all the other Amigas — even cheaper than an A500. But, because of this, one can find awesome deals, because, most of the time, the seller has no clue about what Zorro cards are inside, and for next to nothing, you can pick up a fully loaded A2000 with an '030 or above for peanuts."

    But unless it comes packed with a video card and an accelerator, there's not much point to even messing with it today. What you really want if you don't actually care about Amigas is a CDTV and/or CD32, which takes up minimal space, looks minimally crappy, and runs most of the respective software library depending on whether you want the old or newer chipset.

      Accurate if you only want to emulate the 68000-based versions. Anything with cache (020 or higher) and timings are off.

      But is that even important? Caches themselves introduce execution trace non-determinism (certainly in the presence of interrupts and multitasking) because you don't know in advance if the memory reference is going to hit or miss. The program can't rely on timings in those cases (it's my understanding that this is why Cortex-M for real-time control doesn't have any caches at all - if you really have to care about worst-case behavior, trying to improve the average case may be pointless for many applications).

      For most applications it is completely unimportant.
      To my knowledge this only matters for demos. Among those it is very common to turn off the system and make assumptions of how the cache works.
      A trick that sometimes is used on 060 is to assume 16-byte cache-lines on 16-byte boundaries and use a tst.l from a long-address that spans two cache-lines.
      As long as the condition codes aren't used the execution won't be halted by the fetch. That way you can make sure that the CPU reads in data ahead of time so that it already is loaded to the cache when you use it.
      Interrupts and task switching doesn't really happen often enough to make tricks like that useless even if they are enabled.

      For the 020 there is no data cache to worry about. Instead there is a 256-byte instruction cache. This means that it is common for situations to occur where you can split a loop into several sections where each section fits in the cache.

      Anyway, the point is that since the CPU was more or less fixed the Amiga demoscene were able to make assumptions on how the cache and pipeline works and would optimize accordingly. This means that if you want the emulator to run everything at the right speed you have to emulate the cache.
      For regular applications you just want to run things at the fastest speed possible and games written according to Commores guidelines will work regardless of speed but might suffer from more or less stutter depending on the emulator.

    which is the primary reason why not to buy one. The zoro cards, especially ethernet can be hard to come by, so unless you get a loaded one... well it's pointless.

    I've also had issues with bus noise by maxing out a 2000 with a bridge board, 2065, 68038 upgrade, and ram card. It really was incredibly unstable.

    The 2000 has the same CPU as the 500, and 1000. It really was a pointless model. The 3000 and 3000T's are much nicer. And I should add the even a bare 3000 is far more stabler than a loaded 2000.

    The other issue now is WinUAE is so good, it can run BSD, AMIX, along with all the software from the Amiga heyday. Considering how funky old machines can be, why even bother?

      Lots of old computers are plagued with battery leakage. Got macs like that also.

      Sure, WinUAE rocks, I like it. You know what else I and others like to do? Tinker around on the original hardware. It's why I still have an Amiga 1000, 1200, 4x3000 (they need work though). I enjoy using my Amiga 1200. I enjoy using it's mouse, it's OS, on it's hardware. Listening to the floppy drive.

      Maybe it's reliving the past, maybe it's a waste of time, but it's how I enjoy wasting my time. I'm sorry you had bad issue with some Amiga hardware. I've had funky machines in the past (and still today, got a nonworking liquid cooler the other day), and yes, we understand you don't like it, bad experiences, you are very glad computing has moved on. Cool.

    Actually, the accelerator and the genlock slot are both special-purpose slots.

    What you really want to find inside of your Amiga 2000 is an '030 accelerator and an Emplant board with some Mac IIci roms on it, as well as a boatload of RAM (1 or 2+4MB, maybe?) with a fat or fatter Agnus, and some 2.1 ROMs. If you don't have all of those things, then you will always be tempted to blow more money.

    All of this has made me wonder if I can score an accelerator or at least RAM expansion for the A1200 for a reasonable amount of money, though. That would be a fun casemod (separating the keyboard and the rest of the machine) and I've got one lying around. I was supposed to give it away but crap happened.

  4. I owned one (several) by PhantomHarlock · · Score: 4, Interesting

    I owned just about every Amiga model put out in the US, but the A2000 was the workhorse business machine. Coupled with the video toaster card and lightwave it was a video production tool that cost about 1/10th to 1/100th of what it would cost to assemble all of the discreet machines it replaced. With the addition of the Flyer card it also became a non-linear editor, a tough feat in those days. I did a lot of good work with my A2000. I had the SCSI controller and a hard drive (probably 40 - 80 MB in those days)

    I was also big into Amiga gaming as it was way ahead of its time compared to PCs and Macs. You would pop in something like Shadow of the Beast and just marvel at the arcade quality parallax scrolling and really nice stereo sampled sound using all those nice custom chips that PCs and Macs did not have.

    The linked article is very short on details (there are many) for those of us who lived through it, but even after all this time my own memory of specifics of things is basically gone.

    A good book to know why all of this did not last or evolve is "The Rise and Fall of Commodore". For those of us who started with the C=64 era and went out till the end with the Amiga, it's an enlightening and sometimes frustrating read about the politics behind our favorite company.

    I think that outside of serious collectors and computer history museums, trying to maintain and fiddle with the hardware today is, well, a dedicated hobby. Best of luck. You're often better off with the emulators out there to get your feet wet.

    Within the limitations of technology at the time, the Amiga era was a grand ole time, and we all knew we had the best at the time. Thanks to marketing by other companies who think they invented everything, it will indeed likely be relegated to a forgotten footnote of personal computing history. For those of us who lived it, it was a way of life.

      One of the things I used my Amigas for was Animation. We used it at the Animation studios as a Line Tester (Pencil tester).

      We had a camera attached to a digitizer, and pencil-test software that could run a sequence of sampled images in real time, according to a so called "Dope Sheet", as the Amiga wasn't strong enough to decompress video in real time without external hardware - it was just bitmaps stored in the Amigas memory and the "Fatter" the Agnus...the more Blitter memory could be used to display these images in sequence - direct and raw from the memory, this made it possible to show 25/30FPS movie sequences (typically those photos we took of our hand drawn characters) and could thus check upon our own hand drawn animation to see if it worked as it should.

      The Amiga was an awesome tool for this purpose. I think some of the schools still use Amiga for this, it wasn't that long ago I serviced a few for them.

  5. As an ex. Commodore Service tech by MindPrison · · Score: 4, Interesting

    I can tell you I absolutely LOVED the Amiga 2000, this is my most re-purchased Amiga ever. I've had the A1500 (sort of a scaled down 2000) and it's bigger sister (Amiga 3000), A500, and even the A1000 with it's signatures inside, but the Amiga 2000 was exciting to me because I could expand it into oblivion.

    Unfortunately cool stuff like the Video Toaster...never made it to Europe (AFAIK, I never saw one except in promos on American TV), but I remember I always wanted one, instead I had to make do with the lame VLAB that bugged out most of the time.

    I remember paying $$$ for even the A2091 harddisk controller, and even a small fortune for any xx-mb harddisk back then. The Amiga 2000 was a reliable work horse, I ran my BBS with several modems on that one back in my Demo-Heydays. I loved it for its external keyboard, it felt so much better to code on when I had my Amiga keyboard in my lap instead of that HUGE oversized A500.

    Ah, the demoscene, fond memories!

  6. SCSI madness by Zobeid · · Score: 3, Interesting

    I had an A2000 which I soon put a used A2620 card into -- that was the 68020 accelerator which effectively quadrupled the speed of the system. (When was the last time you saw an upgrade card do that??) It was the same card Commodore used in the A2500. It was an amazing machine for its day, not only in terms of graphics and audio, but for sheer processing power.

    The thing that always drove me up the wall was SCSI adaptors. They were always tricky to get working -- fiddling with dip switches and jumper pins on the drives, and terminating resistor packs -- and I never had one that worked for a long time. It seemed like there was a steady churn of companies putting an Amiga SCSI card on the market, then going out of business, then another company would take a whack at it. I think I burned through half a dozen completely different SCSI adapters.

  7. A500+, A600, A1200 by rvalles · · Score: 3, Insightful

    Because they're way too big, plain and simple.

    The collectible ones are IMO the keyboard models: A500+, A600, A1200.

    A500+ is the good ECS one. With 1MB chip and kickstart 37 pretty much guaranteed. I don't own one, but I have an older A500 with the little mod to get 1MB chip, which is almost as good.

    A600 is the "bring along" one as it's smaller. Supporting IDE HDs is obviously very convenient. Kickstart 37. Real problems include hardware tending to break more than A500+ and software requiring numpad, which the A600 lacks. Lack of expansion options used to be an issue, but there's some interesting hardware now, such as a crazy fast (relatively) FPGA based accel board.

    A1200 is the option with AGA. I own one paired with a 68030 accel board. Together with whdload it's godly for playing Amiga games on the real hardware.

You can pick up an Amiga 500 for around 100$ so that's still affordable if you want to play SuperFrog or watch some cool demos from the glory days of the DemoScene. The action is found on the AGA platform though (A1200 - A4000)

It was fascinating, because Rossendorf was in communist East Germany, and the Amigas probably were bought half-legally for obscene amounts of (east german) money.
