PWB350794A (smaller letetrs). No ROM's on this board. There are 2 and 1/2 sets of DIP-Switches. (20 switches total). There is another board piggybacking the main board, with 36 ROM's on it. This board is labeled PWB350958, ROMBOARD 34M A1A-1. YEA! Love this one. Wow, is it difficult though! My most recent aquisition, yet another auction mystery-board that turned out to be a good pick. This game has a very definite "Aliens" influence in its' art style. Generally just an all-around fun shooter. It features both side-scroller and top-down levels throughout the game.
