Love Mata Hari. Played one at the PHOF years ago and couldn't stop thinking of it. Have one in the garage waiting for restore this spring/summer. New playfield, plastics, and cab restencil. Mint backglass with the writing on the dagger. Can't wait!

By pop bumper ghosting I am assuming you mean that the pop fires randomly without the ball coming in contact with the pop skirt?

Sometimes this is a bad switch cap, and other times it is just noise in the data lines and unfortunately cannot be totally rectified. Just a quirk of this Bally system where some games do it and others don't.

Mine fire independently during game play. Is there a cap on the tilt assembly on the left hand side of the cabinet where the roll tilt ball is?
