I don't know about the SPEC data being pure bs, but your numbers for the 
Pentium systems certainly are: the 66mhz Pentium systems ALL have 66mhz 
data buses, not 33mhz data buses -that's PCI speed.

OTOH, the IBM 601 machine IS running with a 33mhz data bus, and has no L2 
cache.


Add cache to that machine and rerun the benchmarks. Given your emotional 
position on the subject, you will be unpleasantly surprised.
