6. Remove the eight screws that secure the Connector Board to the rear panel. Two screws
are longer than the others and have spacers located between the screw and the rear panel.
See Figure 3-9 for the locations of the screws and spacers.
Note
: Do not remove any other hardware from this portion of the rear panel.
7. Remove the Connector Board.
Replacing the Connector Board
Refer to Figure 3-10. The Connector Board is designed to work with a number of different
keyboards. This is determined by the position of a diode(s) on the Connector Board. There are
four diode locations, D19 through D22, located between J306 and J307 on the Connector Board.
If you are replacing the Connector Board with a new one, determine the location of the diode(s)
and be sure the new board matches the board you are removing.
