Speaking of this, is there any easy way to tell whether a given
processor is v7, v8, or what?  The examples given here were making it
look as though v7 were approximately sun4c, but then Romain Dolbeau
wrote of a dual-v7 SS20, which means that v7==sun4c is not correct.

Right now, for example, I have two SS20s running.  One is

mainbus0 (root): SUNW,SPARCstation-20
cpu0 at mainbus0: TMS390Z50 v0 or TMS390Z55 @ 75 MHz, on-chip FPU
cpu0: physical 20K instruction (64 b/l), 16K data (32 b/l), 1024K external (32 b/l): cache enabled

and the other is

mainbus0 (root): SUNW,SPARCstation-20
cpu0 at mainbus0: RT620/625 @ 125 MHz, on-chip FPU
cpu0: 256K byte write-back, 64 bytes/line, sw flush: cache enabled

If either of those is v7, then, yes, I have a v7 machine in live use
right now. :-)
