Brilliantly engineered game.. But it is boring - Just my 5 cents
Watch out for the AUX DRIVER board as well. The TIP 102s are nearly ALWAYS blown off the board. If the voltages is missing from either the two diverters, drop target or up target coils then the game will not play correctly. You can tell if there is an issue because the fuse will blow and then balls will be continually served.. Just going off memory here, but I don't think I've EVER played a working game...
