I have a nonworking Ms Pacman that I have been troubleshooting. In searching the internet, I have read from TwoBits and other sources that the RF filter board is not needed and recommens that it be removed. After removing the RF filter board,I fired up the machine and everything started working.

The RF board had a yellow ground strap connected to it. Do I need to connect this ground strap to the main board now that the RF filter board has been removed? If so, where should I connect the ground to the main board?
