Bally Slot Machines

Bally Slot Machines: The Complete Service Manual for Electro-Mechanicals 1964-1980.
This book is what the type says, nothing more, but certainly nothing less!

This really is the service manual you need when you own any of the many machines made in these years.
All different types and mechanisms are explained. There's the exploded diagram with parts. There's the electric schematic of how it operates. And there's a whole lot of information by the author on how to service and repair it.

Basic information of how slot machines work, how to read schematics, how to maintain and restore them, and much more is also explained.
