Cabinet 1: Defender
Original Defender cabinet that appears to have been converted twice. I'm guessing Stargate, then Double Dragon.
To attempt to restore the original Defender graphics. To remove the old Defender electronics, and rebuild the electrical items to the right side/wall of the cabinet. To create a system to insert 3 to 4 different boards/systems simultaneously, and make it possible to swap them efficiently.
