Irix 5.4 is IIRC the last version running on the
Indigo. ... If memory
serves me correctly, there was also a Plan9 port at some time, but I
won't bet on it to still work
The Plan9 open source release omits the SGI IP22
stuff, sadly.

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.
The Crimson, technologically speaking, is contemporary to the R3k
Indigo. The Crimson used the same (slow) bus as 80s SGIs, but had their
top-end CPU in it. It was an upgrade path for existing SGI customers.
If I recall correctly, the only way to get an R4k CPU with the old IRIS
GL graphics boardsets. (VGX and friends.)
While the first-generation (R3k) Indigo was similar to the old PI
systems, the second-generation (R4k) Indigo guts were extraordinarily
similar to the Indy. Nothing in them is common to the R3k Indigo. I
expect they only used the old non-PS/2 keyboards to avoid confusion.
