At the moment I'm working on a Bally Sound Deluxe board for a Heavy Metal Meltdown.
The board boots correctly, but doesn't make a sound.
Main amplifier works correctly, pre amp replaced, no result.
With the help of an oscilloscope I've looked at the PIA select and the signal goes all over the place.
I suspect a bad PAL chip.
I can find the chip, but not the data to programm the PAL chip.
Can anyone help me?
Peter
