Grounding of JAMMA pins 27, e: Refer to the Figure 3 for JAMMA pinouts. The initial JAMMA standard indicated that these pins were signal grounds. However, many gameboards have repurposed these pins for button inputs. To use pins “27” and “e” as button inputs, leave the pins vacant, as shown in Figure 5 below. To modify these pins to be grounded, apply jumpers (also commonly referred to as shunts). -

Troubleshooting: My controls are not responding – JAMMA harness Ground wires fed from pins 27 & e of the gameboard: Several instances have been found where the JAMMA harness wiring uses pins 27, e as a grounding takeoff point for the control panel wiring. If your harness does this, the Switcher will not respond to any inputs from the control panel.
