I think that a 50MHz SuperSPARC with no cache in that machine will run
at 40MHz, since the SS10 doesn't have a 50MHz Mbus speed.  The SM51
(50MHz SuperSPARC w/ 1MB Ecache) will run the Mbus at 40MHz, and the CPU
module at 50MHz.  So, the SM51 should be a bit faster, but not hugely
fast.  The SM81s are nice, but generally modules for these machines are
quite expensive for the performance offered.  :(  Of course, that
doesn't make them any less fun.
