Self Test, Statistical Display, Troubleshooting and Service, 6. This manual really is a complete guide to repair, setup, and maintenance of both the S slot (not very common) and the S+ slot, the most common 3-Reel slot, and includes progressive slots. The troubleshooting guide and parts list are particularly important so you can order the correct replacement parts, including lamps, and switches, from either distributors or dealers. There are literally hundreds of different S and S+ slots all based on this platform. It includes most of the 3-Reel favorites, such as Red, White, and Blue, Wild Cherry, Double Diamond, Triple Diamond, etc. The IGT S+ slot machine is the most common of privately owned modern slot machines. The photo is of the book you will receive, and has a slight printing flaw (void) in the upper left side of the cover. A single used copy on is for sale at over $150.
It's long out of print, so there won't be any more.
