Hi,

Just picked this keyboard up and wondered if anyone knew anything about it. It looks like an IBM Model M, but the keys aren't in the slightest clicky and I think are rubber dome. No LEDs on it, but it has an AT style connector. I don't have any working PCs with an AT keyboard connector so I've just ordered an AT to PS/2 adapter to test this with. I wonder if it'll work though as it's off a terminal it seems going by some of the button labels. There are 12 dip switches underneath - any ideas what these do?

Cheers,
Steve

I finally found an ATX-PS/2 adapter so I plugged the keyboard into a PS/2 port on a PC and it kind of works! I get numbers and letters, but most of the other keys don't behave like you'd expect.

I'm trying to find a DOS util that will show me what key has been pressed so I can try and work out the mapping that it's doing.

Cheers,
Steve

the enter key looks unequivocally IBM, doest it have buckling spring switches?

These are Honeywell domes if memory serves me correct. Lots of keyboards tried to look like the Model M in the very late 80s to early 90s, NTC KB-6151/various Keytronics/Chicony KB-5181, list goes on. Same went with the Model F for earlier 80s boards.

Nah not buckling springs, feel like rubber domes.
