Hi there; I've got an old SGI 9500801 keyboard (along with the Indigo it works with) and I'm investigating my options for bringing it back into use as the keyboard for my (Linux) desktop machine. I know it's the one with the proprietary interface: my current thinking is to interface it to a Pro Micro ATmega32U4 board and write some code to convert its signals into USB. I'm kind of surprised that no-one seems to have done something similar before though, so I'm looking for some advice before I start:
- I've seen that old SGI keyboards are in demand to some extent: do people buy them to interface to new systems, or to strip for parts?
- This keyboard seems to be a plain serial device: has anyone looked at connecting it's output to an ATmega23U4 and interpreting what it sends?
Cheers,
-Mark.
