&
COMPONENT IDENTIFICATION
Since FUNBOUSE uses WILLIAMS ELECTRONICS GAMES' WPC Electronics System, a new
technique to identify connectors and other game components must be introduced . Each plug or
jack receives a prefix number (which identifies the circuit board), a letter, and a number.
J-
designations refer to the male part of a connector. P-designations refer to the female part of a
connector. For example, JI0l designates jack 1 of board 1 (a Power Driver Board Board jack);
P306 designates plug 6 of board 3 (a Display Driver 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, JI01-3 refers to pin 3 ofjack 1 on board 1.
Other game components may also have similar prefixes preceding their designator to clarify their
locations or related circuit. For example, F501 refers to a fuse located on the Sound Board .
Prefix numbers for the WPC circuit boards are listed below.
1- Power Driver Board
2- CPU Board
3- Display Driver Board
4- Dual or Single Display Board
5- Sound Board
