The Williams Pinball Controller (WPC) is an arcade system board used for several pinball games designed by Williams and Midway (under the Bally name) between 1990 and early 1999. It is the successor to their earlier System 11 hardware (High Speed, Pin*Bot, Black Knight 2000). It was succeeded by Williams/Midway's Pinball 2000 platform, before Williams left the pinball business in October 1999. FunHouse (designed by Pat Lawlor) was the first production game to use WPC, although there are prototype Dr. Dude machines that use WPC.
