The Amiga, Circa 2010 — Dead and Loving It

Orion Blastar writes "While many Amiga users have moved on to Linux, Mac OS X, and even, gasp shock, Microsoft Windows, some of us don't want to give up so easily. There are two open source projects that are keeping the Amiga legacy alive even if Amiga Inc. seems to be deader than a doornail and not really doing much but selling old Classic Amiga games for new platforms. Like WINE, there was a project to run AmigaOS 3.1 software for Linux and other platforms, but it evolved instead into an open source operating system named Amiga Research OS, or AROS. AROS is best run inside an emulator, and while it is not a modern OS like Linux, it can be downloaded and run inside of Linux (and the downloads section has more). While it is not ready for prime time yet, it is a promising OS that is being ported to many platforms and uses the user friendly Amiga GUI we Amiga users grew up with." Read on for more. "OK — maybe AROS is not modern enough for you, and you like Linux instead. Then you might like Anubis OS, as it is a hybrid of AROS and Linux. Much like when Apple took NextStep (based on *BSD Unix and the MACH kernel) and the classic Mac OS to make Mac OS X, this project wants to take Linux and AROS and do the same thing.

For those who want the classic Amiga, there is UAE, the Universal Amiga Emulator, which needs kickstart ROMs and boot disk images to work. You can buy them from Amiga Forever; the emulator comes with all the files you need plus other goodies.

For the classic Amiga 68K series, it is recreated via the Minimig, which uses SD cards instead of floppy disks; a must for retro computer hobbyists. AmigaOS 4.1 exists for PowerPC based SAM 440EP systems like the SAM 440Ep systems and parts sold here. (I am not associated with Amiga Kit or Amiga Inc. or any Amiga company. I am just an Amiga user since 1985 and very much into retro computing.)"

    I never owned or even used an Amiga, but I can't help but respect the longevity of its influence.
    Don't listen to the disparaging remarks on slashdot. I would never have known even the little I know about Amiga, had it not been for the articles here on /.
    Obviously reality matters (time and commitments etc) but if you guys can build a system in your own time that works keep doing it, it may even become a big deal to every one some day. enjoy

  3. Re:A few great Amiga ideas I'm still waiting for by AndrewStephens · · Score: 4, Interesting

    I had an Amiga and it was great, however the world has moved on since then. To answer your points:

    1. To shutdown the Amiga, you turned it off. There was no delay, no Start->Shutdown...wait possibly forever...

    No, you waited for the disk light to stop flashing and then turned it off, hoping that all applications had flushed out all of their data. The Amiga got away with it (mostly) by not really having a lot of long lived service-type applications.

    2. Sliding screens. Why not give each application its own full screen and allow the user to pull down the top menu to slide between these screens.

    I do miss this - having each application on its own screen (with its own screen mode) was very useful. Now that we are all running high-res desktops with 24 bit colour, the different screen modes aren't so important, and software like "Spaces" on MacOSX fills much the same need.

    3. Simple speech device. What could be easier than "LIST > speak:" to say a directory listing?

    That was cool, but fairly niche. I am disappointed that computer generated speech as not come further, the MacOSX voices sound only marginally better than the old Amiga voice from 25 years ago.

    4. Bidirectional linked list filesystem. If you lose a sector or sector link, most of the file could be rebuilt by following links from both ends towards the bad sector. (Disk doctor)

    This was very useful on unreliable floppies, but used precious space on the disk and made updating files slower. Now that removable storage is more reliable the trade-off doesn't seem worth it.

    5. The keyboard garage. The 1985 Amiga 1000 keyboard tucked neatly under the computer where it didn't take up desk space, was hidden from children's fingers and was spill-proof.

    6. Tight integration of hardware with O.S. O.k. this works against everything we've been taught about abstracting everything but since the PC world has boiled down to little more than an O.S. monopoly, a hardware monopoly and a graphics card monopoly, why not eliminate some of the levels of abstraction that will never be used and make my 2Ghz PC perform every day tasks at least as well as my 7Mhz Amiga did?

    What you are basically wishing for is MacOSX, where one company controls both the hardware and the software, and it does (suck it, haters) produce better computers. However, even MacOSX has abstraction layers and drivers because Amiga-style direct hardware intergration turned out to be a terrible long-term plan. The clever hardware tricks that made the Amiga1000/500 so cheap and fast back in the early 80s ended up holding back Amiga development 5 years later.

    To sum up, while the Amiga was (in a lot of ways) ahead of its time, modern computers (and I am including Windows in this as well) do more and operate in a different environment than in the 80s. Although the Amiga was fast and amazingly inexpensive for the time, for the equivalent money today you could buy a high-spec iMac that is better in every way. Those who pine after the lost Amiga are living in the past.

    Not entirely convinced that Windows 95 was to blame. The Amiga- which was *the* machine to have in Europe in the late '80s to early '90s- had already been losing ground to the PC on one side and the Mega Drive and SNES on the other for some time before that.

    Commodore had sat on what was basically the same once-revolutionary core hardware and OS for 7 1/2 years with only minor improvements. The A1200 and A4000 offered some notable (but not revolutionary) improvements, but should have come out *at least* a year earlier- by the time they hit in late 1992, the ground had already shifted, and many people had already moved away.

    I'd say that '95-'96 sounds about right, regardless of Windows 95. After Commodore went bankrupt in mid-'94, the Amiga was in limbo, stagnating for more than a year. Eventually, in late '95, the new owners announced that they were going to start selling the same, unimproved, three-year-old A1200... for £100 *more* than it cost before the bankruptcy!

    They claimed that they had to do this to make their money back, but whether or not this was true (or just a cynical attempt to milk the diehard fans of a doomed format) it was clear- to me at least- that there was no way that this was going to be a success, and that the game was quite obviously up.

    Windows 95's launch probably just emphasised that the market had moved on, and that the Amiga had already missed its final chance to catch up.

  5. what personal computing lost by Anonymous Coward · · Score: 4, Interesting

    Here are a few things that personal computing lost when the Amiga died.

    * Abstraction of data handlers from apps. Datatype handlers were stored in their own directory. You could drop new ones in, and more or less *every* app of that type (sound/video/images/text/etc) would suddenly be able to read the new format. No farting about with "this app only handles image formats X and Y, but not Z". Drop in a datatype for Z, and it now handles Z. Sound editor didn't support saving in mp3? Drop in a datatype. Now it (and every other sound app on your system) does. It wasn't perfect, and some apps didn't support it, but many did.

    * Single metadata format for everything. We now have 92340860159 different file formats, many replicating the same functionality as other ones. The Amiga had IFF (Interchange File Format). Ok, eventually all the stupid PC formats (then typically without any metadata to speak of and far less well designed) were supported, but originally IFF was just about it once you got above ASCII. Apps could be built to handle just a subset of the data from a file- e.g, just the sound from a video multimedia file, for example. You could parse the container without having to understand all the data in it. Granted, there are many other formats now which do that, but in the 80's it was groundbreaking, and with ONE container format instead of a million, you stood a much bigger chance of any given app supporting the scheme. To boot, it was open: most apps published their storage formats, and were typically good about using established standards for images, movies, sound, etc.

    * About 10 years of time loss while DOS and later Windows PCs caught up to what the Amiga started out with. Who knows where we'd be now if they hadn't been so far behind from the start.

  6. Re:Platform makes Mac look cheap.... by toejam13 · · Score: 5, Interesting

    There are a number of reasons why the Amiga could run so well using a 50MHz processor or slower.

    1) The OS used a flat memory model. The entire address space of the 680x0 looked the same to all processes. So there was no slowdown doing page table translations on a per process basis.
    2) Every process could read and write to every other process's memory. One process could pass a memory pointer to a second process, which would then have direct read-write access to every data structure the first one had. No having to pass huge amounts of data using semaphores or pipes.
    3) The GUI was very primitive. The BOOPSI widget subsystem was about as bare to the metal as you could get. Even extensions such as ClassAct/ReAction were very minimalistic. That made it very fast.

    Of course, that all comes with a price.

    1) The flat open memory model meant that any sort of malicious software could eavesdrop on any other memory location without bother. Stealing passwords or silently copying data from your word processor? No problem!
    2) That same memory model meant that any program could go outside of its bounds and trash any other program in memory, including the kernel. That's why Amigas tended to crash more often than even Windows 95 boxes.
    3) Memory fragmentation was horrible because the OS had no form of garbage collection. You couldn't move allocation blocks around in memory because there was no form of abstraction, either using Win32 style handles or virtual memory pages.
    4) No memory tracking / garbage collection. If a process closed without freeing memory, it was gone forever. After a while, you'd run out of memory and would have to reboot.
    5) Every modern widget toolkit around today, including Qt, GTK+ and Cocoa, generally make BOOPSI look absolutely prehistoric. Try doing any sort of raster or Unicode based apps under AmigaOS. You'd probably have to write your own BOOPSI extensions to get what you want.
    6) You would have hit the 4GB limit of the 68020/030/040 much faster had the platform remained around unaltered. That's because every process would share that space. With OSes like OS X, BSD and Windows, each process gets its own 4GB (~3GB after kernel reservations) to play around in.

    Yeah. Even your mobile phone has an OS with better memory management and UI functionality than your Amiga 4000.

    Fullscreen windows. Why slide them up and down when you can switch with Alt+Tab or Cmd+Tab. Also check out Virtual desktops, you might like them.

    It's difficult to compare with modern operating systems, but the sliding windows were really clever. Each screen could be a completely different resolution with a different colour map and screen format. If you Alt-Tab between full-screen applications of different resolutions, you can still only see one at a time. With the Amiga, you could see all of them at once. For example, if you're playing a full-screen game today and alt-tab to the desktop, the game will typically switch back into a window and the screen will switch to the desktop resolution. The Amiga method would let you simply drag the full-screen game screen to reveal the higher-resolution desktop behind it, without forcing the game to swap back to a window. Even virtual desktops aren't as clever or flexible as that.

    Most of that is very true. The amiga's memory management was the biggest problem and they did tend to crash if you had badly programmed apps. In general use however it crashed far less than win95 and even less than 98. It wasn't until win2000 that I saw a microsoft operating system that I actually considered superior to the amiga. Unforunately the hardware couldn't keep up after the death of CBM.
