I picked up a 1979 Williams Tri Zone pinball machine that needs lots of parts and work. I got it cheap and it'll never be a show piece but it should make a good 'player'.
The MPU and driver boards worked when I got it, so it's mainly been some reliability mods and caps for the sound and power boards combined with replacing missing and broken parts.
