This is the small board that ties together all three boards of an Atari Star Wars or Empire Strikes Back PCB set. These are equivalent to the Atari boards, but smaller. If your original is missing or damaged this will take its place.
Double sided PCB has traces on one side but the through holes are plated and have pads on both sides. Save some money by purchasing your own edge connectors (TE Connectivity part 1-5530843-0) and warming up the soldering iron. The board also has holes for optional standoffs so your board does not slide in too far and short against the back of the cage (use Keystone part 8824).
