Nothing terribly unique about this game (just that it's fairly rare...). Common components, and disassembly is simple: 8 phillips screws on the bottom (two in the battery compartment), and then open the game upside-down so the controls don't fall everywhere. Phillips screws on the control panel and main circuit boards will free everything except the power leads and the speaker (these would need to be de-soldered to completely free the circuit board). If your game is dead (or you know you plugged in an incorrect power supply) replace the two transistors on the main circuit board. They are cheap, and 90% of the time it resurrect your game.
