Hello Nathan,

Back in the day, IBM would offer systems with CPW ratings that spanned up
to a factor of 10 for the exact same CPU, which was just clocked up or down
in order to meet CPW targets. It kind of rubbed some of us wrong to know
that the CPU was clocked down for "marketing" purposes.
Sure this was also on the low end machines? Especially the 150? 99.3/49.65 MHz is really unusual odd clocking. I'm tempted to seek a faster crystal to try. :-) Most often, there are parts of the hardware running synchronously, others asynchronously (like PCI slots, being fixed to 33 MHz). I wonder what would happen with a 124.125 MHz crystal (aka 62.0625 MHz CPU clock) — if such an odd valued crystal oscillator exists, that is.
:wq! PoC
