Yep.  Sorry about that.   I was looking under the heat sink last night and
the CPU markings read 110 MHz, and I guess my fingers grabbed that number
instead of the 120 MHz speed the machine actually runs at.   Although,
truth to tell, I'm not sure if that board was a 120 with a 110 CPU or a 90
with a 110 CPU.  It seems kind of odd that they would put a 110 into a 90,
since they'd have to also change the resistors on the voltage regulator
because the 100+ MHz PPC601s use a lower supply voltage.  On the other
hand, this board didn't have the peltier equipped heat sink, so I don't
think it was a 120, though the heat sink could have been changed before it
reached me.
