Here are the pinouts for the DB-9 Mouse/Keyboard Connector. The connector on
the DB-9 is unique to the 4D/25 and is not replicated on any other SGI model.
However, by making a conversion cable you can use any sgi -/+12V keyboard/
mouse using an EIA-232 interface. I've done this for my 4D/25 and it works
great. Any of the Single Tower, Twin Tower or Predator (Case types)
keyboard/mouses will work; i.e., Crimson, etc.
Pinouts:
1 N/C
2 KRCD - Keyboard receive data - input
3 N/C
4 -12V DC - Power
5 MRCD - Mouse Receive Data
6 GND
7 +12V DC - Power
8 KTXD - Keyboard transmit data - output
9 GND
