Well, the SB-1 is a MIPS architecture processor (a MIPS64 one to be exact) and as such not within the MIPS II - MIPS IV ISA range and what you say by definition stands for any other MIPS architecture implementation too. This is not relevant though as MIPS64 code won't run on a MIPS IV processor such as the R10k anyway. Maciej
