Major havoc boardsets that were meant to run in a Tempest Conversion (ie using a
6101 monitor instead of an amplifone) had slower crystals in them so that the
monitor could handle the drawing rate.
  Original boards had a 12.0 and 10MHz while the conversion boards replaced them
with a 10.0 and 8.9MHz respectively.
  You can tell a 'conversion' board just by playing it because the sounds are
about 3 steps down in tone, they also play much slower, which is probably good
since you just can't do as much with the tempest spinner compared to a nice
roller! :-)
