I've recently repaired three of these board.
All were "off-key" and didn't sound right.
I tunned out to be U2 the CD4042, which is the data interperter for this board.
All three boards had the same problem.
This is what happens if you get wroung voltage over your data signal.

Bally games always switch off the coin lockout coil when there is a ball in a eject or hole.
Gives the cpu more time to do other things.
This also happens during bonus count if I remember correctly.
