They really aren't that different "problem wise" from any other game from that era. Each manufacturer has it's own issues and there is documentation to bullet proof all of them. Gottlieb's main issue is connector related, once you get past that and have it running, keeping it running is a piece of cake as long as you don't do something dumb like work on it with the power on.
