Did it have a solenoid in the case? Might explain the 8.5V I don't recall seeing anything resembling a solenoid. The area of the case around the keyboard was completely empty, besides the keyboard assembly of course. If there was one it would have to have been mounted elsewhere which doesn't make m...

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 ...

Honeywell Keycap Font?
Hi! Sorry if this is in the wrong place but I was wondering what the name of the font is that was used on the keycaps found in Honeywell keyboards and what seems to be most keyboards from around that era.
