There's sun4, sun4c, sun4d, sun4m, sun4u (hmmm, I wonder if sun4u applies to the E10000). The 4/xxx series were all sun4 except the 4/150. 4/150, SS1, SS1+, SS2, IPC, IPX, SLC, ELC are all sun4c. SS 6xxMP/yy, LC, LX, voyager, SS10, SS5, SS20, SS4 are all sun4m. SS 1000, SS 2000 are both sun4d. The SS10, SS20, SS6xxMP/yy, SS1000 and SS2000 are the only non-ultra multi-cpu Sparc configurations from Sun.
