Got me an early MIPS workstation, an RC2030. I'm

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).
