Looking at the schematics on page 255 of the friendly manual you linked to, in section "Keyboard -- Z4 Socket Pin Assignments" I smell a hint of the same sort of protocol as for the the IBM 5291 terminal keyboard. There's a "Kbd Strobe" and eight "Kbd 1...7" lines too. I suspect the "Kbd O" or "Kbd...

Damn, I wish I could. My parents got tired of it sitting around and tossed it while I was away :cry: I wasn't too ...

From the photo it looks as if you could tap into the lines you need and install an xwhatsit. You would need to get busy with the multimeter . I thought that might be a possibility as well. The way things are routed and the chips at the bottom of the board made it seem like this matrix might be set ...

Converting an IBM 5120 Beamspring to USB

Honeywell Keycap Font?
