I just bought the game drilled the front lock to get backbox key and look under playfield found several fuses that were blown and just lying where the coin box goes and a used coil. Got the backglass out and found that the mpu board had acid damage, but I had the altek altimate board from another game and a sylinoid bord from altek also. I cleared the memory and set the game switches and the dip switches like the other board don't know if they were right or not, the game booted up I know the sound board needs fixing . The problems I found are the saucer or kickout on the left side does not work or the bottom bumber on the left either when you drop a coin in a credit is added when you mash the start button it takes the credit away and puts ball 1 on the display but a ball does not eject into the shooters lane. You can put the ball in shooters lane and play game the spinner adds points as does the bumbers up top the roll over switches add points as does the other targets, you let the ball drain and ball 2 pops up on display the scores work so do both flippers . When you do the test a ball will pop into the shooters lane ,I the driver board has one coil that lights up I think its q 12 and when I looked on the old board the transistor looked burned at the board. When I looked under the play field no bare wires or loose wires the switches are cleaned but its like the kickout and bottom bumper and ball eject have no power I usually buy electro mechanicals I have one other early solid state machine memory lane but just don't have much experience on solid state machines THANK YOU TO EVERYONE THAT HELPS

thank you I will try that when my other parts come in I just borrowed the boards from a game I have at an arcade will have to wate until its closed again to get the boards back to test the game again
