Thanks, simon My suspicion was that the DELAY() calibration based on
CPU speed is slighly too low for the 3100 and 2100, and this tends to
confirm it.

There's a code fragment in sys/arch/pmax/dev/lk201.c which
does DELAY(100) between the mouse self-test and setting the mouse
into auto-report mode.  Michael Hitch was going to try changing
that to DELAY(1000).  

I think an even safer test is to try changing the  two

lines in sys/arch/mips/mips/mips_mcclock.c (nominally for 2100  and 3100) 
to be

which is the same DELAY() multipiler that the 5000/200 is using.
If that doesn't work, we need another theory.

(Apologies to those with 3100s, I cant easily get mine booted right now.)
