Everything is working great now on the pinball machine. Pretty amazed with how complicated the play scenarios are. Quite impressive how the multi ball countdown works, and also the control of spelling F-I-R-E by using the right flipper.Last remaining issue to fix was a previous repair that had been done to the driver board. After removing the wires that were connecting pins on IC5 and IC4, repairing the traces that had been cut, installing new transistors and replacing one of the 7408s chips controlling solenoid 7 everything is now working.
Glad the shield is working again, tough game without that.
Next I'll be buying some acrylic paint and touching up a few rough spots on the play field, will also try to find some new targets and order new stickers for them.
Hi
ReplyDeleteSo has the over heating problem been solved in the removal of the 56 bulbs? In any case a cooling fan is needed as the equipment is old and subject to over heating
