Confirm the Correct PCB Before Service
These prerelease drawings may differ from later production Atari boards and from Namco hardware. Compare the PCB layout, component locations, connectors, drawing numbers, and revision markings with the board being serviced before testing signals or replacing parts.
Safety warning: Arcade cabinets and CRT displays may contain hazardous voltages. CRT displays can retain a dangerous electrical charge after power is disconnected. Use a qualified arcade technician when you are not trained to work safely with arcade electronics.
