I have acquired a bally roller derby machine that has been unplugged in a garage for over 30 years. It is unique in that it has a payout mech which will dispense coins for any credit you have. I lubricated all parts that are supposed to move, and cleaned all contacts with spray. I turned it on, and it came to life. The more
I play it, more features come alive. As of now, I can get extra balls, but the correcponding lights do not stay lit. Also, the magic screen will not move after the second ball is played. Any suggestions?
