Williams PIN-BOT - Alphanumeric Master Display

CONNECTOR
IDENTIFICATION
WILLIAMS ELECTRONICS
GAMES
uses
a
special technique to
identify
connectors.
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,
1 Ji designates jack 1
of board
1
(a CPU
Board jack);
3P6 designates
plug
6
of board
3
(
a
Power Supply
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, 1J1-3
refers
to
pin
3
of jack 1 on
board
1
.
