data east batman . worked well for a few months, and one day on starting a game, starts spitting all 3 balls into the shooter lane. also, outhole kicker goes crazy, licking its brains out. if you put the balls in play, and they drain, it kicks them all out again. also, after about the 30 seconds, the knocker goes crazy, knocking way, but never adding credits.

in switch test, all 3 ball trough switches work correctly. shooter lane switch also works as intended. outhole switch too. there are no switch errors. if its going crazy, and i unplug the switch matrix connectors, it will still keep firing the outhole, knocker,

no stray voltage on the matrix connectors, checked with scope. no acid damage. had ver 1.02 software , swapped in rottendog mpu with 1.06 software, its exactly the same. no better, no worse.

it this point, i dont even have a theory what could be wrong. any ideas??

i just though, new anypin ram, but same processor chip . could it be the 6808 ?
game is far away, dont want to go back with out some kind of plan.

thanks

thanks
