This is an original copy of Bally's 1978 document F.O. 560-1 "Repair Procedures", "Module & Component Replacement". It's in good/very good condition.

It contains 72 pages bound with staples.

This is the intro on page 1:

"F.O. 560-1 supercedes and replaces F.O. 560. The purpose of F.O. 560-1 is identical to that of the earlier procedure. It is still a two part service procedure. PART I deals with servicing the game on location, primarily by MODULE REPLACEMENT. PART II, COMPONENT REPLACEMENT procedures, deals with servicing known defective modules to the component level; A known-good game must be used as a test fixture."

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.
