SM-71's will also work providing the bootROM is fairly recent.

It's not advisable to have a mix of different processor type/speed if you
install multiple CPU's. One other CPU module that will work in a Sparc 10 is
the 501-2431 SM-52X, which are basically two SM-51's on the one board.

The older SM-41's will also work. If you do intend to install more than one
CPU, it's not advisable to use any of the non-cached CPU modules, so avoid
the SM-30's, SM-40's and SM-50's.

SM-51's are 50 MHz, SM-61's are 60 or 65 MHz (I'm not certain off the top of
my head). SM-71's are 75 MHz, and SM-41's are 40 MHz.

SM-41's, SM-51's, SM-61's and SM-71's are fine in a Sparc 10. Most of the
Ross hypersparc modules can be used too, as long as the bootROM is fairly
recent.

Craig.
