    Hi all!

    I've developed a ISA board for one single TRAM, compatible with the Inmos B004
    board.

    It is able to run the software I've developed in 1993-1996, along with the old
    Inmos software.

    I've wrote an article about its development https://nanochess.org/transputer_board.html

    The files are in my git https://github.com/nanochess/transputer/pcb


    Nice board, Oscar!

    What do you do with the other three TRAM links ?

    I seem to remember the T412 (??) boards used mouse extender cables to
    get two flipped pairs end to end.

    Cheers, Andy!

    The extra 3 links aren't connected.

    I couldn't determine if there is a standard for connection, but now I think I could expose at the very least the links in a connector. And it would need also a way to disable the board port decoding to avoid conflicts.

    I vaguely remember someone using 0.1" headers on a ribbon cable, and
    someone else using RJ45 (or perhaps RJ11) connectors, and CSA's
    Transputer Education Kits used 8-pin MiniDIN connections (with LocalTalk-compatible cables, I think?)

    I don't think there was an official standard?
