Yes. You can find the document that describes the SP611 in the downloads but that is a very old chip and you might consider moving to a newer one in the future.

A Reel chip which contains the theme of the machine is defined by a PAR sheet. PAR= Paytable and Reel.
This is basically a description of the game, %% payback, reel strip numbers, all the real and virtual stops how many coins like 2 coin or 5 coin etc. There are no options to set but it does define the game TYPE.

Type 0 means no special features where as a Type 2 would be a nudge game like double diamond deluxe where the reels nudge up or down based on the direction of the diamond. Other themes like Balloon Bars only nudge up, and Slam Dunk only nudge down.

Subsequently you need to use a game chip that supports the TYPE as defined by the reel chip -  almost all game chips support type 0 games while others pull support 0,2,5 etc

Each game chip basically contains an operating system.
You can set all sorts of machine options.
A PSR is a Program Summary Report that details what options there are and how to change those options.

For instance certain themes with a SP731 game chip would support a selection of 7 songs that play when you get a winning combination. The 1271 chip (much newer) is basically the same functionality but the song selection was dumped to make way for more accounting and statistical registers that the Nevada gaming board deemed mandatory.

The PSR would also tell you what SET chip to use. With the 1271 the set 90 chip can also be used to set an internal IGT progressive as well as allow compatibility with linked progressives (large overhead displays) that link a bank of machines together with a single shared progressive. With the 731 chip you use a basic SET 15 chip strictly for the bill validator.

Any S+ can be any theme and be a 1 coin, 2 coin, 3 coin, 5 coin, 1 line, 3 line, 5 line, 9line/9coin by simply having the matching Game and Reel chips along with the matching reel strips and glass.

There are also tournament chips that allow you to play as fast as you can for a set period of time or play a set number of credits. The combinations are pretty endless.

I have 3 S+ machines - two are the 9” top glass style (often called a chop top), and the other is the other 16” style. I have over 60 game kits and I have both 9” and 16” top glass for each.

Each machine has a IGT internal progressive that I use as the second award and then I have a linked progressive with a display in the player tracking bar of each machine and a 36” overhead display. I also have this linked into a PE+ video poker machine.


In a real casino you would never have a mix of slot and poker on the same progressive but it’s all compatible / doable and as I like to
say my basement my rules ….

In my last house I had an 18’ progressive sign over my bar but my current place is not conducive to
this so I am Still trying to figure out what to do with the spare parts that my wife will accept.
