I think that looks like a nice rxample of an original game. Those pf’s can blown out but this one looks very decent Mylar bubbling also common. The scratches on the pf glass are typical and if it bothers you this isnt too expensive to replace for a standard tempered glass version. Cosmetically i say its average to above average for an original. Good find.
The backbox GI lights are def out. GI is a fairly simple circuit. Look for a burnt connector on the bottom right side of the interconnect board.
I’d pay 2k for that no problem and you’d never lose a dime on it.
