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

Well I have finally managed to find the correct keyboard for this system.

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.
