Steve Kulpa's Bally Page

All information on this page pertains to the first generation of Bally Solid State machines (Power Play, Mata Hari, Freedom, etc.). This includes the -17 and -35 MPU boards and the AS2518-16 and -22 Solenoid Driver board. Some of the information I'm presenting here I learned while servicing my own boards, some I got out of the operator's manual, and a whole lot of it I learned by reading Clay's Bally Repair Guide, which I HIGHLY recommend.

As I learn more about additional Bally models, I'll add it to this page.
