System 80 switch column 7 (coin door and tilt)
Column 7 is used the same way on most System 80 games even when the manual leaves it off the matrix chart: 07 coin door test button, 17 left coin, 27 right coin, 37 centre coin, 47 replay/start button, 57 ball roll and plumb bob tilt, 67 usually the outhole, 77 normally unused.
