My first home-brew CNC stuff ran off a '286 PC with only 7 mHz. clock. I
use a nice old '386 in my lab, and it's clock is around 20 mHz. The 33 mHz
'486 is MORE than sufficient! You only have to change the "delay loop numbers"
in your software to maintain the desired OUTPUT-rate.



I now have a Pentium3 Compaq which came with Win.95 running my home-brew
lathe, but that '95 got corrupted, and updating to '98 would have cost as much
as a new computer, so I just FORMATTED it and loaded ONLY MSDOS and GWBASIC,
and it works fine, so long as I put in HUGE delay-loop constants in the
step-subroutines.

I can see NO reason to have speed faster than a couple megahurts clock for
CNC purposes, so long as you know how to jiggle the output-rate by changing
constants in your op.sys.
