To date I've scored:
2 Space invaders (same location) trashed playfield on both, but other than a TON of burned out 44's, working 100%
Fishtales out of a burned building. Pretty much tarshed, but was great for parts. Electronics were completely intact.
Devil's Dare, 98% working, out of a house that was recently bought, new owners wanted it out ASAP as the wife was "NOT about to have any satanic icons in her new home" Ok, problem solved!
Many, MANY video video machines--Tempest (not working) was the best score!
