I picked up this Space Station not long ago. The guy said "It has some incorrect coils, and one or two wiring hacks." . Nothing that prepared me to see this:
A hacked in Data East SS Flipper board and some Frankenstein flipper mechs. Love the power supply hook in, and solenoid coil floating around in the bottom. I pulled that s#it out and repaired the loom, and installed the original equipment, it's a fantastic game... now.
