My bad, thought you were trying to put multidenom on an S+ machine, which can't be done. On the S2000 platform the multidenom setup depends on which credit display type is present. If the maximum number of digits that can be displayed is 5 then a push button on the button deck is recommended, but touch screen can be used with an additional adapter harness. Ifthe maximum number of credits that can be displayed is 6, then the touch screen is recommended. In either case, there must be a multidenom capable version chip installed on the MPU and extensive programming with a key chip will need to be done. First place to start is by finding out which credit display is present and which parts will be needed
