Currently got this one on my work laptop. Model M terminal board with internal converter. The only layout changes I made versus a normal 102-key are that RCtrl is is a Windows key, and the four keys along the right side of the numpad are =, -, +, and the normal Enter.
This one was fairly late, like 1998, so it supported โnormalโ keycodes. I was able to wire up a completely standard โSoarerโsโ converter and simply use dupont connectors on the internal header. The cord itself is just a random one lying around, with a cable tie for strain relief.
Oh nice! Thatโs always been a deterrent for me, that the key codes are different, and I would need a translator midline, which I didnโt want to deal with haha this is MUCH nicer!
So, I donโt want to send you the wrong way with the technical details, but whatever this keyboard does, a Soarerโs Converter worked fine and it did not require me to have any deep understanding of how the keyboard worked. I understand the Hasu Converter software for the same MCU and wiring can convert damn near anything.
