Um, not quite.... the pinouts are different. 3100 uses an r2000A,
which has an r3000 core, but an r2000 pinout. THe r3000 has integral
cache interface,a nd the r2000a needs more external logic, or some such.
I think one place this shows up is in synchronizing with writebuffer drains,
but dont quote me on it.


I think the mouse is an FAQ....
