Early WPC games (Funhouse to Popeye) to 120 V

Steps

• These games use the same transformer plug as Data East: rewire it the same way.
• Change the main power fuse and the MOV as for a Data East game.
• Set the country jumpers W14 to W18 on the CPU board to "America"; each position takes a 0 ohm resistor or wire link. Some early WPC games differ, so check the inside front cover of the manual.

Line voltage is present in the power box, line cord and transformer wiring; unplug the game before working there.

Systems

• WPC Alpha-Numeric
• WPC Dot Matrix
• WPC Fliptronics
• WPC DCS
