Well, many thanks to the people listed below for their quick
responses and many apologies for the slow summary. The answer
to my question is: yes the sparcstation-10 can support multiple
cpu modules, but the cpu modules must be 40 mhz or above and the
boot prom must be version 2.12 or above. Once you satisfy those
restrictions it works great. There is even a dual processor
card so you actually get up to four processors in the machine.
Again, thanks to:
