The changes taking us to the 2nd and 3rd
versions were mostly due to pricing combina-
tions requested by foreign counties, and elec-
tronic coin accepter support for the U .K. Any-
thing 3.20 and above is a good version of the
program.
Williams will upgrade anyone that still has
version 2.00 in their games.To the best of our
knowledge, all of these games have been up-
graded already. There is no need to update ver-
sions 3.20 or higher.
Murphy's Law #1106
Rock-Ola 478 that intermittently locks-up on
power-up. The control panel LEDs just flash.
Sometimes it cures itself, and at other times I
have been wiggleing cables and boards when it
comes back.
SOLUTION
Try pulling loose all of your connectors and
checking the pins and fingers on the PC boards
for oxidation. If you are able to remove all of the
connectors and reseat them and eliminate the
problem, most likely you just have dirty connec-
tors. (I've got a 4 7 4 that does this. I just reseat
all of the connectors every time I collect and it
works fine, one of these days I'll get around to
doing it right.)
The other thing you could try is swapping out
the credit control unit with a known good unit
and see if that fixes it (assuming, of course, that
you just happen to have one laying around).
