I just joined @pinsiders today. I recently purchased the 1978 Williams World Cup Soccer Game from another individual. It worked for about 15 minutes. Then the credit button stopped engaging the game. Not sure what happened. The pervious owner had set the game to free play by having a wire in the coin mechanism in the coin door. With the move or play, that might have been disengaged. I'm also told that test 4 readout number 5 should be set to 00 for freeplay. It is currently set to 20. How do I get it set to freeplay? Also, is there anyway to reset to all factory settings? Thank you in advance for your help getting this game working again.
