Effective with software version 6.06, programmers Joe Katz and JT Harkey are credited on the backbox display. Dennis Nordman built the original house model and the concept for the original witch mechanism. Matt Riesterer was the sculptor and fabricator of the toys and other items. At our request, he listed them for us: Ruby slipper flippers, Munchkin huts and roofs, the witch legs in the house, the witch castle walls, the throwing apple trees, the witch, the State Fair balloon, and the topper. In addition, he co-created the laser-cut Oz head, helped design the crystal ball, and helped with the powder coating. This model is advertised as having a special numbered plaque for the first 1000 games made. It is actually a sticker affixed to the lower apron.
