I just picked up a few project pins: "Fire", "F14", and "Road Kings".
Of course I immediately starting digging around the internet for documentation and schematics. Each game had an instruction manual with schematics, pretty good! However, after going through the manuals, I noticed a few missing items. No playfield schematic. No board interconnect drawings. Overall lack of good electrical prints for all three machines.
Does anyone know where I can get some better electrical diagrams in general, and for the playfields specifically?
