That's the middle revision. -003 was the first one, and it'll only run
the R4000 and a few of the R4x00 CPUs. You should be fine on R4400 with
-005, but you don't be able to run R5000 without a PROM upgrade.

I don't believe R4600 is newer than R4400. I seem to remember them
coming out at the same time on the Indy. The only real difference is
that the R4400 is optimized for floating-point operations, and the R4600
is optimized for integer operations.
