The clock chip/crystal issue was in the back of my mind...but I hadn't
given it that much thought.  One thing I was wondering was this:

I have heard that the 030@50mhz chips are internally clockdoubled.  I am
wondering if this is indeed true.  If so, I would think that I'd see an
increase in processing speed, but not in external I/O.

I don't understand much about the internals of processors...I'm more of a
software person.  I suppose that my primary question is this:  if I were
able to pull off a faster processor and clock speed, would this cause
problems with some of the OS timings in MacBSD?

Thanks.
