There are two chips that control the S+
These are the Game Chip and the Reel Chip.
The Reel Chip is pretty much the theme like Double Diamond, Black Cherry, etc.
The Game Chip needs to be the right "Type" for the theme and is basically the operating system and governs the settings.
Typically there could be 5, 6 or even 15 different chips that could potentially work with the reel chip.
So to answer your question regarding max payout and hand pay - it depends on the Game Chip.
On the older game chips the settings were controlled by dip switch settings on the MPU board - generally there is a sticker on the board tray that explains the settings. 200, 300, 400 and software.
If you choose software then the limit is set by the chip. The later game chips ignored the dip switch settings all together.
In the older chips the dip switches also determines the reel sound and reel speed.
In the newer chips there are a number of settings. Wins go to Credits or Wins go to Tray, Max Hopper Pay settable from 1 to 9999, Max Credits, Bills to Coin, etc.
In some of the chips between the older and newer there were no separate credit settings.
Now you might ask Why would someone want to use an older chip
The 731 chip is an older series of the very common 1271 - The 731 had a choice of 7 songs as win music "Were in the money...." etc that were later abandoned to make way for more accounting.
Another older chip that is occasionally used is one that supports Montana Credits. Normally if you have a 2 coin game - you put in 2 coins and then your options are to play or cash out. The third coin goes straight to the coin tray. With Montana credits as you drop in more coins they go to the credit - so feel free to load up 500 coins if your pockets are deep .....
With regards to Printers and TITO. If you red the S+ electronics manual close enough there is support for a printer vs a hopper, but I have never found evidence that an IGT S+ printer existed, nor the mods necessary for the Belly to support such a beast. Secondly the S+ didn't support SAS communication, which would be necessary for it to talk back to a central computer, validate the ticket, and apply credits.
To this extent the notion of going cashless on a S+ is usually through a hack, such as attaching a slotted cardboard or plastic wheel to the inside of the hopper. As the hopper spins the fins or slots of the attached wheel pass by the coin optics and the S+ thinks its ejecting a coin. The coin head is then replaced with a plate, and the only way to add credits is through a bill. Several people would leave the machine setup to look like quarters but set the bill validator to 1c so you get 100 credits for a dollar bill. Other people simply remove the wire on the Cash/Credit button and set a relatively low hand pay amount, when you clear the hand pay you have 0 credits on the machine.
In Mexico City the casinos are cashless - you go to the back of the building and trade your $$ for chips or tickets. You enter a bullet proof man trap where one door opens, you step in, the door closes behind you and the next door opens and they deal with you from yet another sealed cage. Everything has tinted glass so no one knows your business. Walk in with your friend and the overhead voice asks that one of you step out, if you have a jacket on they ask you to take it off, and turn around.
- I believe I saw a S+ that had been outfitted as a TITO machine but the bill validator was plated over and the ticket in/out was in the player tracking plate so it was completely separate from the native workings of the machine.
