Bally Cheap Squeak A080-91603-C000
$100 + $5 shipping
New Bally Cheap Squeak sound board with licensed ROMs.
All chips included. ROMs permanently set for 2732 or 2764 ROMs with no jumper changes needed (not a combo ROM).
Fixed an issue in the original Bally design that could lead to a solenoid locking on if when the cheap squeak processor is in reset. This also stops the potential pulse of the out hole solenoid at power on.
Tantalum capacitors have been replaced with Samsung 10uF, 50v X5R MLCC capacitors.
Improved grounding. Less likely to have noise from the displays than my original Bally examples.
