 There were two versions of the IRIS Indigo, the original R3k and the R4k
model.

 The R4k Indigo can indeed take R4000 and R4400 processors. There are like
3 choices:

 Processor Module 1 (PM1) which is an R4000 @ 100MHz

 I'm not sure what it's called (perhaps also PM1), but it's an R4400 @
100MHz.

 Then there's PM2, which is the R4400 @ 150MHz CPU module that's used in
an Indigo2. I've got one of these in my Indigo and it works very nicely.

 The Indigo uses a proprietary keyboard and mouse... the plug may look
PS/2, but it is not. It's actually a serial keyboard (same kind that can
be used on a first generation Onyx I believe).

 Serial Numbers for the Indigo keyboard/mouse are:

Mice (interchangeable):
   9150800 (mechanical, beige, 3' cable, minidin6)
   041-0141-001 (mechanical, granite, 3' cable, minidin6)

Keyboards (interchangeable):
   9500801 (beige, no attached cable, minidin6)
   041-0136-001 (granite, no attached cable, minidin6)
