For my first pinball machine I kind of made an impulse buy of a '78 Williams World Cup for $75. Playfield was in decent condition with only a few minor things missing. Backbox was empty of any boards / displays, the backglass looks "okay". Also found that all of the wires from the bottom had been cut off at the point where they would go up to the backbox.
So far I was able to find the missing playfield plastics and purchased an MPU board off ebay at a decent price that's already been gone over and tested. I am wondering if taking this on will be a complete money sink trying to re-wire everything or to slowly work on it little by little picking pieces up as they become available to me. Working on getting more photos added.
