My Gottlieb adventure , it started with a trade and i ended it up with two non working sys80 projects ( MGOW , HH ). then a friend said " if you really want to go all in with sys80 " Black Hole . Haunted House has left but Devil's Dare has tahing it's place . I need help with sound because i know nothing when it comes to Gottlieb sys80 sound ( but can check for power lol ) . I would say i'm novice pinball tech , but when it come to chips 0/100 .

Here are the issues

Mars god of war
when i power on sometimes souds stuck on , on/off a few times and it"s ok

Black Hole
only speech in attract mode ( iv"e check the settings )game play no speech and sounds are not right

Devil"s Dare
sounds locks on after multi-ball

Any help is appreciated

Thanks

Denis

Black Hole fixed , Pascal board was set at classic instead of speech . Rookie mistake lol . WOW what a difference .

MGOW same issue with switch #25 on or off , game has new rotten dog board but has same issue with Pascal board in it .

Thanks

a little late but finally got to work on those problems .

MGOW replaced 6502 on sound board and that buzzing sound when you first turn it ON is gone

DD i don't think it's the sound board . i suspect the orange I.C. sockets on MPU or a bad diode on 1 of the switches .

the game plays as it should but randomly she locks on just the back ground tune , no scoring or any other sounds . back ground sound until game over then back to normal . everything ok for maybe 1 game , then it's locked on back ground tune .

Any leads is appreciated
