Ben,
     thanks. I was a little concerned about core voltages since
there's conflicting info out there (some sites say the 333MHz CPUs
were Klamath units which wanted 2.8v and only the 350/400/450 were
Deschutes, others cross referenced the part numbers printed on the
slot-1 cases as being Deschutes, 2.0v units. The voltage regulators
don't provide voltage info, and the online cross references I could
find didn't include that info either. I didn't want to plug a 2.0v
celeron into a 2.8v slot.

     There was another slotket buried in there that had a voltage
regulator, but no indication of dual capable. Maybe I'll try it first
set to a safe voltage to be sure, then go for broke on the duals if it
works at the expected settings.
