Strange stuff with FG. Been in the herd 20 yrs, always works fine. At pwr up, it comes up tilted. It will start a game, but each ball is tilted. 5vdc pwr good, 7 flashes good. Also, came up in 3 ball mode, with dip switches in 5 ball.
Of course, it did all this at Fridays pin party.
Swapped U10, and unplugged mpu J2 with no effect.
