Thread: IBM PC-XT with a strange IBM keyboard

    Default IBM PC-XT with a strange IBM keyboard

    Hallo allemaal,

    Today I picked up this XT at the home of a friend. This XT is mentioned in: another thread. When loading it in the car we noticed that it wasn't the usual PC keyboard but an AT one. So we wondered if there was a XT board inside the case.

    Being at home I opened the case and there was a XT board inside. I powered it up and worked fine, no message of a missing keyboard. Very puzzled I had a better look at the keyboard and only then I saw it wasn't an AT one. The main difference is that where I expected to see the LEDs for CapsLock, NumLock and ScrollLock, there was nothing: just the rectangle that marks the place. I googled of course and so I ran into the model M. But nothing mentions the version I have.

    Info: made in the UK at 03-07-1986 (European notation) and various numbers. Sorry, I cannot make pictures at he moment.

    Any ideas? TIA!
    With kind regards / met vriendelijke groet, Ruud Baltissen

    The last version of the XT BIOS contains support for 101-key keyboards, and a few Model M keyboards have support for XT signaling, and have no lock lights. It sounds very much like you have this combination, keyboard part # 1389969
    Offering a bounty for:
    - The software "Overhead Express" (doesn't have to be original, can be a copy)
    - A working Sanyo MBC-775, Olivetti M24, or Logabax 1600
    - Documentation and original disks for: Panasonic Sr. Partner, Zenith Z-160 series
    - Music Construction Set, IBM Music Feature edition (has red sticker on front stating IBM Music Feature)
