The critical thing is: does it have a TLB (that's memory management
and mapping hardware). No TLB, no Linux. Otherwise, the R3900 is an
R3000 superset and will happily run vanilla R3000 code.
Of course you still have to get the right device drivers and stuff.

Completely different. pSOS is a microkernel running threads in a
single address space. Compared with other real-time OS' it's fairly
well supported, fairly expensive, and doesn't need too much memory.
