got a firepower with a puzzling issue. game does a reset every time, if you hit the flippers at the exact same time. slightest delay hitting one, then the other, and no reset. it has a previously replaced rottendog mpu and the power supply is an orig williams, but was installed previously to " solve" this problem. i put a scope on the mpu 5 volt test point, doesnt dip below 4.9 with the flippers hit. solid 5 v otherwise. i changed all the flipper diodes just in case, no help. any ideas?? i also disconnected the lane change, just to see if that was an issue.
thanks
