Can I use a PC
mouse/keyboard with that?
You cannot. You need to use a SGI keyboard and mouse.
I have plugged a PC
kybd/mouse into a SGI Crimson and an Octane
and they seemed to work OK.
The Crimson and Octane are much later in the product line than the
Indigo. The Indigo is after the Personal Iris but before the Indigo^2
or Indy. There's a point where SGI switched to using PS/2 compatible
keyboard/mouse connectors, but prior to that they used a special
interface that would either fry the interface circuitry or the
kbd/mouse if you tried to use a PS/2 compatible kbd/mouse on them.
The frustrating part is that the connector is identical but the
voltages and pinouts are wrong.
