Variations

There are six vari­a­tions of the WPC hard­ware. The orig­i­nal ver­sion is some­times re­ferred to as WPC-89. The WPC MPU re­mained the same through all gen­er­a­tion up to the ad­di­tion of the se­cu­rity chip in WPC-S, and then the sub­se­quent WPC-95 board. The vari­a­tions are as fol­lows:

WPC (Alphanumeric)

• FunHouse – September 1990
• Harley-Davidson – February 1991
• The Machine: Bride of Pin·Bot – February 1991

Some Dr. Dude ma­chines were also made using this WPC gen­er­a­tion, al­though most were made using the later Sys­tem 11 board.

WPC (Dot Matrix)

• Gilligan’s Island – May 1991
• Terminator 2: Judgment Day – July 1991
• Hurricane – August 1991
• The Party Zone – August 1991

Ter­mi­na­tor 2: Judg­ment Day was the first to be de­signed with a dot ma­trix dis­play, but was re­leased after Gilli­gan’s Island, due to Ter­mi­na­tor 2 hav­ing a longer de­vel­op­ment time than Gilli­gan’s Island.

Twilight Zone was designed to be the first pinball machine to use the new DCS system, but due to delays of the new hardware design it was decided to release it on the old hardware (using downsampled sound effects) instead. The redemption game Addams Family Values also used the DCS Sound System.
