I recently acquired an untested PC Jr, matching monitor and the "Freeboard." It's in great shape but is missing some stuff. I was missing the power supply -- so I just went ahead and ordered AkBKukU's ATX adapter for it. When I had it open, I found it had the longboard power supply and the 64k RAM expansion. I also noticed that the IR receiver is missing ... so I have no way to use the keyboard. It came with two phone cables as if those would work with the keyboard -- but not the proper keyboard cable. Luckily the computer does appear to work but of course ERROR B so I can't boot all the way.
Reading the Technical manual, they discuss the keyboard protocol. (The IR and Cable protocol is basically the same serial connection.) Does anyone know if anyone has replicated this protocol in code so we could use an ATMega to use non PC Jr keyboards with it?
And how about making the RJ11 to "pin" cable so I can try to use this thing?
Thanks!
