I just got this board from KsArcade. No fault of Keith!
ROTTENDOG MPU / DRIVER COMBO FOR WILLIAMS SYSTEM 3, 4, 6 AND 7, MPU327.
It replaces the MPU/Driver board for Black Knight and several other pins. Just want to see if anyone has run across this issue. It says in the directions but only after i installed the board, to remove the metal bracket that is in the backbox before installing the new board. Well i did not do this and screwed the board in. Well the metal bracket was touching the back side of the board and when i cut the game on it messed it up. The game will not play. It comes on and lights up but will not come out of factory reset. Can not play it at all. Had a friend look at it and it looks like the board is ok but must have fried a chip. Any ideas on which chip?
