Main Control Board: The printed circuit board that contains all the

electronic components needed to operate the scoreboard and console,

and therefore is considered the "brain" of the system. It is located inter-

nally on the right-hand side of the scoreboard as you face the board. See

Figure 3 below.

Figure 3: Main Control Boards

Note: Two types of control boards are used in scoreboards

depending on the year the scoreboard was manufactured. The

control board used before December 1998, #2860 board is illus-

trated in Figure 29, page 5-1. The control board that was used

after December 1998 is the #0066 - 4290 board (See Figure 30,

page 5-2).

Individual Digits (either nine or twelve inches in height): The

seven-segment flip displays that are found in the scoreboard, display

numbers for the various functions, i.e. "Score" and "Time."

Data Cable: The communication cable that transmits the data and

audio signals from the operator's console to the scoreboard. See Figure 5
