This pattern holds in nearly all cases; the digit before the slash is the family (2=68010, 3=68020/68030, 4=SPARC), then the first digit after the slash is the processor board type, and the second digit is the chassis type. This does break down in cases such as the SPARCstations, in which (for example) the Sun-4/60 is a SPARCstation-1, a 4/65 is a -1+, and a 4/75 is a -2, but the numbering scheme does hold for the VME machines at least, with the only exception I'm aware of is the 3/110 which was an odd CPU board that they didn't seem to use anywhere else. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
