I've got two SM50 CPUs in my SS20. I want to upgrade. How do these compare: 2xSM51 2xSM61 2xSM71 1xRoss HyperSPARC Dual 100MHz. Obviously the SM71 would be the best choice out of the SM51/SM61/SM71 choices, but what about the Ross? -- Eric Dittman dittman at dittman.net Check out the DEC Enthusiasts Club at http://www.dittman.net/
