Hi. I recently got my hands on a 1967 Williams Apollo pinball machine and have been trying to get the thing restored. I have struggled with faults on the electronics and have removed, stripped and cleaned everything in the back box and under the playfield. I still have the thing doing something different every time I switch it on. It is also refusing to reset. Can anyone give me a steer or tell me where to find a wiring diagram. Im about to use it for fire wood. Clive
