Hello John,
Universal machines (8116 series) have limited programming.
The settings are done with DIP switches on the CPU board.
There's two sets of DIP's on the CPU board. The DIP-4 (on main board) is for progressive settings and the DIP-8 (on a sub board) for maximum hopper pay out, credit choice, type of coin optics, type of coin hopper, type of pull handle optics and max bet at the start of the game. The DIP's are usually set once and forget.
The green "TEST SWITCH" and red "COIN SWITCH" are used for troubleshooting.
You may want to familiarize yourself with the "ALL CLEAR SWITCH" on the CPU board. There's a hole in the CPU cover about bottom-center that will allow access to the push button. Remove the coin tray and the coin hopper to get a better view. You will need to use this switch when ever you change the battery, Eproms, DIP settings, have memory corruption, etc.
Another thing to check is the condition of the battery on the CPU board. It's a soldered in Nimh battery for which the CPU board recharges. The battery is positioned next to the program Eproms and acid damage from a leaking battery can quickly kill the board.
