The connector is 6P6C, unlike the DEC and Wyse, which are 4P4C. There seem to only be 4 distinct signals, though.daedalus wrote: 07 Mar 2020, 11:03 It would also be interesting to know whether they are Wyse or DEC compatible (the DEC LK201 and Cherry G80-1306 run off 12V, whereas the Wyse boards run on 5V)
Power going into the keyboard is 12V. Or rather anything from around 6-15V. It goes into an LM340T-5 right away. And then the keyboard itself is all 5V. The control signals are TTL as well; there are no special serial voltages like in the LK201.
The protocol is mostly XT Set 1: almost all the graphic keys line up and some of the control keys do, too. With some remappings, and aside from needing the higher voltage, Soarer's converter works for input. It doesn't try to do the LEDs, so I don't know whether that part of the protocol is different.
