Pretty much what the title says, I've got two EM games and enjoy using logic, following the schematic, jumping connections, and adjusting switches while keeping them running at 100%. I would love to get at least one SS game with some depth eventually, but am scared of the circuit boards. I've done some electronics work in the past modding an old gameboy, but have no real idea of how to find problems on a circuit board. I'm sure the mechanical bits of the play field are fairly similar to EM in principle, but it's the computer underneath that worries me. Opinions?
