im installing a remote battery holder on my world cup and wanted to know how to identify the positive and negative with the original holder already clipped? there does not seem to be any indication on the board itself?
thanks

Quoted from ChrisHibler:

Williams World Cup, the System 3?
If so, here's a pic of a System 4 MPU, which is similar. The negative side goes to the connection that touches the large ground plane on the perimeter of the board.
