I have a nice Bally Embryon for sale. Everything is working. Its in very good condition. Some artwork touch up was done and then clear coated over (in the center looks great and upper right of the playfield looks not so great.) The cabinet is nice and solid. All original boards with memory capacitor installed and the mpu has new pins and connectors. Speaker has a low hum. The backglass is flawless it looks like new but is original. No broken plastics. Solid cabinet with only minor nicks.
