CONNECTOR & COMPONENT IDENTIFICATION
Each plug or jack receives a number that identifies the circuit board and the position on that board that it
connects to. J-designations refer to a male connector. P-designations refer to a female connector. For
example, J101 designates jack 1 of board 1 (a Power Driver board jack); P206 designates plug 6 of board
2 (a CPU board plug).
Identifying the specific pin number of a connector involves a hyphen, which
separates the pin number from the plug or jack designation. For example, J1 01 -3 refers to pin 3 of jack 1
on board 1.
Other game components may also have similar numbers to clarify their locations or related circuits. For
example, F501 is a fuse on the Audio Video board.
Prefix numbers for WPC circuit boards are listed below.
J1XX - Power Driver board jacks; F1XX - Power Driver board fuses
J2XX - CPU Board (There are no fuses on the CPU board.)
J5XX and J6XX - Audio Video board (AV board) jacks; F5XX and F6XX - Audio Video board fuses
Schematics for standard WPC baekbox boards are found in the WPC Schematics Manual.
Playfield, cabinet and all other baekbox board schematics are found in this section.
