    Default Gemini GM925 80bus serial keyboard anyone ?

    Folks,

    I have just acquired this Gemini Z80 based 80bus computer - model GM925.

    Problem is that it dod not come with a keyboard and seems to use a proprietary serial keyboard with a 6 pin DIN connector.
    Extract from the system manual for the interface board shown in the attached image.

    Can anyone recommend a potentially compatible keyboard or am I going to have to build an interface ?

    Thanks

    Where did you end up finding it? Congrats. I ran into the same problem last year with an ITT system. The keyboard was harder to find than the system itself. By total luck a hardware collector I know had one in his pile.

    I bought it along with a whole bunch of Gemini 80Bus processor cards from a chap on Ebay - a lucky find.
