I think actually, the continuous sound is controlled by the DIP switches on the CPU board??
Need someone familiar with GTBsys80b to chime in here... or a manual!
ok i have not touched any of those dip switches.but if any one is familar with those switches ill be happy to check them over. i went into the shop i found the second wire for the door test switch, it was tucked up the back of the door loom, joined touched them together and could shift through each test, all test were fine it does not do sound test which i was anoyed about i was hoping it would test the sounds.
one question what does "game prom-sum 7B3D" mean? came up in the test.
also thank you retropin for taking the time
