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

Hi all,
Any ides if the keyboard and mouse needed for an SGI 4D/25 was used on
any of SGI's other models?
A machine just cropped up for free but it's got no mouse or keyboard
with it. The keyboard socket on the machine is a 9-pin D-type female
(umm a B-type in correct terminology I think) - I'm assuming the mouse
plugs into a port on the keyboard, rather than tying up one of the
serial ports on the machine?
Oh, the root password isn't known either... but I'm assuming there will
be ways around it on a machine this old.
cheers
