This is an original copy of Bally's "An Introduction to Bally Flipper Games". It's in good/very good condition.

It contains 48 pages, spiral-bound. There's no date on it, but as it makes no mention of electronics, I'm guessing it can be no later than mid 70s. If anyone is able to accurately date this I'd welcome that via a 'question' on the listing.

This is the intro on page 1:

"It is the purpose of this outline to summarize the essential components that make up a coin operated amusement game. It is written, primarily, to provide a foundation and background for the men who service these games. No one can hope to memorize every detail of every circuit and component in today’s great variety of games. A good technician does not even attempt it. Instead he should be able to obtain information as he needs it, from the instruction sheets, drawings and schematics provided with each particular game. To do this, he must be able to read and interpret the schematic diagram. The ability to read a drawing, coupled with the basic principles of electricity will make it much easier to understand, adjust, operate and repair ANY GAME or electrical device."

Within AU this ships as a standard letter with tracking, and for overseas buyers, you can choose Express, Standard or Economy. Should eBay calculate a price in excess of what it costs me, I'll refund the difference.
