Got me an early MIPS workstation, an RC2030. I'm trying to track down a keyboard and mouse for it. The keyboard connector uses an 8-pin DIN connector. Anyone have any leads? (Or know what the pinouts and protocol might be?)
I don't know, but having seen quite a few older keyboards I'd guess that it's likely to be RS232 (+/- 12V) or RS423 (+/- 5V). Early SGIs and some 68000 machines I've seen elsewhere were like that, so a voltmeter might tell you something. Early SGIs, for example, were RS423 levels 600baud and up/down encoded (there's pinout and keycode tables in older IRIX manpages).
