Re: Q*bert sound board repair

Thanks Joe :)

David, you might check the 74LS377PC on the main CPU (in the audio output
section of the CPU). It is socketed and sits inline with the signals to the
sound board.

BTW, the dip switches on the sound board don't do anything. They were installed
to work with the Gottlieb factory test fixture and (someone correct me if I'm
wrong) a few Gottlieb pinballs that shared the sound board.
