Note: This page is a work in progress. Please help get it to a completed state by adding any useful information to it.

The WPC system was a Motorola 6809E based platform that ran Williams, Bally and Midway pinball machines through 1990 -1998. The system made its first appearance in a short run of Dr. Dude machines, with the CPU board and the power-driver board replacing the System 11 equivalents. The System 11 code was converted to run on WPC. Next came Funhouse, still with a digit display.
