Thread: Some rarer SWTPC boards.

  1. #1

    Default Some rarer SWTPC boards.

    Currently checking out a SWTPC, to be sold in the upcoming autumn cleanup.
    I noticed mine has quite a few rare SS50/SS30 boards :

    - Memory is 4 PCB's from "American Computer works", based in Oklahoma City. Basically 32 TMS4044 chips with minimal external logic, so 16K per board.

    - No serial I/O, but rather a terminal on a SS50 card : a 6845 based 80x24 videodisplay, with a 6821 directly scanning an external keyboard : The "American computer works" Communicator board :

    Also present is the Compuware 6800CL4 RTC, a SS30 board with the MSM5832 RTC chip.

    All the above are handled within the Flex OS.

    And finally there is an Newtech model 68 Music board, also an SS30 board.

    If sufficient interest I can make the documentation and software available.


    ...and the 6800/6809 should really be getting their own sub-forum !...

    Neat boards! I've had the S-100 version of the Newtech music board, that's fairly desirable so the documentation would almost certainly also be desirable. Personally, I try and preserve anything that's not currently online, and put it online

    ...and the 6800/6809 should really be getting their own sub-forum !...
    Yeah, there could definitely be enough interest for a 6800 compatibles and 6809 subforum, there were a handful of popular/interesting machines that used them, but I don't think any one machine has enough interest to have its own machine-specific subforum.

    Would love to see docs and scans of the boards, schematics, etc. Cheers
