DMD power supply 520-5047 revisions by game

520-5047-00 serves the small-display games (Checkpoint, Ninja Turtles, Batman, Star Trek) and uses an MJE340 and MJE350 for the negative supplies. 520-5047-01 (Lethal Weapon 3, Star Wars, Rocky and Bullwinkle) and -02 (Jurassic Park, Last Action Hero, Tales from the Crypt, Tommy, WWF, Guns N' Roses) use two MJE15030s and an MJE15031 instead. Losing one of the -110, -98 or +68 V lines usually means the high-voltage section needs rebuilding.
