I have my first IGT Gameking I-game. has 3902 MPU. I have the original 3902 board that has some Joker Poker and Keno games. It works properly and have utilized the keychip 22 to change the 12 allowable games. Additionally, I bought a second 3902 with a bunch of other game Poker/Black Jack/Keno and Slots (a 55 game chip set). I would prefer the new board and games in my machine. However, when I swap out the boards, a different style keychip menu comes up. It allows me to do most of the same setup as my other board except it doesnt seem to have a place to change the setting to disable the coin acceptor. I can disable the hopper. When I go to put the machine into play, I get a "coin - in Jam " error message. Am I missing something in the key chip settings? Do I need a different keychip than the 22? I can see everyting else behind the error message. It lets me set the whole thing up but just cant get to play with the uncleared issue. Any assistance would be greatly appreciated. Thank you
