Hey! Looked through schematics, my 3 stack boardset must be different than other Taito SI PCB's. The Gameboard has the LM3900's on it but not in the locations on the schematic.
Does anyone know which LM3900 controls the Invader Hit Sound? Its the only sound that is not working....
Thanks in advance. Pic attached.
