I am considering a 1978 Mata Hari machine in need of restoration.
When powered in, the game seems to cycle through checks... testing bumpers, flippers etc., but never finishes. It just keeps going through the cycle. Digital starts with 89 and then counts 1 - 17 as it cycles.
I know at least one bumper rubber is missing, and not sure if that may be affecting it.
Anyone have any idea what may be occurring & how to fix? Have video of it cycling and can share
