Set a -35 MPU up once for 2732 EPROMs instead of re-jumpering per game

Each re-jumpering stresses the pads and traces, which eventually lift. A better plan is to jumper the board permanently for 2732 EPROMs and burn each game's code in 2732 format; converted 2732 images exist for every Bally game from Freedom (1977) to Cybernaut (1985) except Baby Pac-Man and Granny and the Gators.
