I just picked up a shadow last weekend and it gives me all kinds of switch matrix problems and keeps ejecting balls into the shooterlane.I went into the switch edges and brought up the matrix on the display. Most of the display shows squares except when I unplug a large board under the playfield they mostly go to dots.I dont have a manual yet but does anybody know where I need to start.Also I unpluged the two lower connectors on the cpu and they went out also.If someone could send me a pm with a switch matrix that would give me a starting piont.Thanks ,matthew
