The SGI Crimson uses the same proprietary mouse/keyboard as the Indigo and
its predecessors, the power series and other personal iris'. The Onyx uses
the PS/2 keyb/mice like the Indy.

You can convert other early SGI keyboard/mice to work with an Indigo (and
thusly, Crimson)... Requires some pinout fiddling.
You can also convert a Sun-3 mouse to work as an Indigo mouse, however I
don't believe any keyboards which exist by other makes can be converted.

If you google for 'This Old SGI' you will find some info about the earlier
SGIs keyboard/mice, which may be able to help you.
