So let me get this right it was pin17-20 on the mpu causing all the outhole probs? I have been doing this intermittenltly for a while. I totally went through the game to get it working and when I got it to my buddies house the outhole and left flipper didnt work. I did everything from rebuilding mpu reset to driver rebuild to PS rebuild and that is what caused it?My 4.7 uf on the sound board kept toasting and I changed it to a axial instead of tantalum. I really thought it was the flipper enable on the sol drv. that is all I didnt replace on that. Holy cow. I think its 18 to set to 93 and 16 and 17 set to 02 while 19 needs to be00 in selftest. dip switch setting are a pain on this game I couldnt beliwve the issues I ran into. The worst was after startup I would run a solenoid test and the outhole would work and then 1 and 3 would trigger the pop bumper. could that be attributed to pin 17-20 problem too? I needed help bad at the time. REAL BAD. you guys know your s--t. is the spy background music playing while gameplay is playing?
