    This is a mee too, if you know a place that still sells it. Same purpose - demo in a museum

    1 a scsi terminator

    3 an IDE connector
    4 a 3.5” floppy disk

    I will try for a better photo - yes, that connector seems viable. I will order a few and keep my fingers crossed. and keep looking….

    Sorry, the “blue ribbon” connectors seem the wrong size - too big by about 25%. I will keep searching….

    Chuck I own some old exchanges with 25 pair connectors The plugs are a good bit bigger - like 2.5”, not the 1.5” that this one is. I think I had some old “disk in drawer” stuff and they were closer...

    I have ploughed through about every cat I can find before turning for help. I THINK it might be an HDCN60 type connected - used by IBM in RS6000 series I have read. BUT nobody seems to stock the...

    OK, I have a number of wee arduino projects for “radar sumulators” on LCD screens (different project/different world). I guess that they are better than the PIs, since the RS232 is there from the...
  11. can anyone identify this IDE disk connector - and where I might get/butcher one?

    I have an old military computer (UK/NATO) probably 486/586. And LXI (or an LX1).
    However I dont have an (easy) way to get an IDE disk into the beast.
    Why not?
    A strange connector on the IDE -...

    Unaware of that feature on the 420/520 that would be very useful. Probably cheaper than the IBM solution, but both were off my radar - so thanks for the suggestions.

    I have a bunch of machines - 70s/80s. I use teletypes on the old ones but they are getting hard to keep in supplies. So I recon a wee converter and some rs232 terminals would be the next best...
  14. Wanted - terminals - UK (Scotland) area

    I am looking for a few RS232 type terminals - not particularly worried if they are vintage or vetran/old. These are to interface to PDP11s of various sorts - when I dont want to demo with my...

    The external case is stamped with +5, -15 and ground. But I had not considered the scan! I was just happy to find the document and not to have to reverse engineer the board ;-)
  16. of course

    Ta. That makes sense. The board is encased at present and I have not opened it up. Still on the "will do I this next" phase. I think it is a christmas project.
  17. KC341-B help understanding the circuit diagram please - MPS - KC7341 too

    I am starting to look at putting one of Jorgs boards behind my KC341-B (some manuals call it a KC7341 AKA MPS). This is a long-term project and I am just in the initial stages - understanding the...

    Harry: That is indeed what I am looking for the sizes of. I can work out height and width (total) but I need some clues about the "upstand" (sticky out bit) at the bottom (circa 1 1/2" or 1 3/4" I...

    I disagree - to a point - there is a metal plate (shown on page 299 of the EK). This plate holds the circuit board (via spacers). The plate then appears to fit to the CPU cabinet. Then the bezel...
