  • Alternate 2200 emulation software

    If anyone is interested, my long-suffering emulator project is on github.

    IS this actually runnable? If so, are there any documentation on how to run it?

    The unit tests are runnable :-)
    No documentation as of yet; startup will be in a readme file. Operations stuff such as keyins, JK settings, how to configure the thing, etc will be part of the system console web interface.

    The instruction processor code is about 2/3 complete.
    IO needs some serious attention.
    Interrupt handling is all there... I'm not entirely sure it's complete though.

    Then... it needs an operating system.
    It departs from the standard SAIL interface in a way that makes it impossible for OS2200 to run on it.
    That could change, but the necessary information to do so, is unavailable.

    I *do* have a significant body of work on an emulated OS, but it's in c++ and will have to be rewritten in assembler.

    The goal is for most (for some value of most) existing 2200 software to run unmodified... And that will still be a long time coming.

    Being in Java, it might be a bit less performant than one would want...
    But it will run on any major OS, and it is actually intended to be run in a container.

    All user interaction is/will be via browser.

    k.

    Sounds like you still have a ways to go. You have my sympathy.

    I recently finished an emulator for the 494. Writing the emulator was the easy part. Writing an operating system for it was a PITA.

    I'm still looking for some original 494 software to run on it but I'm not hopeful.

    So, in the meantime I am writing an Algol 60 compiler for it. That is turning out the be harder than the emulator. :)

    OMG, I haven't even thought about a 494 in 30+ years. I recall someone had part of the control panel (with a clock in it? and the big rectangular light-up buttons)
    on their desk as a decoration, from one of 'em that had been scrapped.
