  Yes, but you can replace the clock oscillator on the '23.  I've had
one running up to 20MHz with no problems.  It was quite nice at the
time.  I just about flunked out of high school because of spending so
much time at home hacking on that machine. :)

  The original 3100 was 2.8, the later 3100s were 3.8.  For the other
"numbered" 3100 machines, the last number is the VUPs rating...so the
3100/38 is 3.8 VUPs, and the 3100/76 is 7.6...
