Quoted from DUKE_WADD:started off with ground shot row 4,5,6,7 and 8 plus other errors. changer the u20 chip on cpu board and all the errors went away except check mongol switch 52, 53. what ever go to try the game start button now doesnt work now. switch test there a whole list of switches not working now start button plumb bob out lanes who knows what else. dont know where to look next guessing somthing wrong on cpu board
Switch test: Short pins J205-3 and J207-1. If it shows switch 13 the cpu board is good (at least that part of it.)
