EMI Shields
Removing the VGM Board
The VGM Board option can be added to any PC88. The
PC88MX, however, is manufactured with the VGM Board
installed.
Remove the 5 Phillips head screws at the rear panel
edge that secure EMI Shield No. 1. Refer to Figure 3.2.
Fold the shield back.
Slightly push to the front edge the cables that cross the
bracket.
Remove the bracket.
The VGM Board is connected to the Engine Board at
location Ji. To remove the board, carefully lift the board
until it is free.
Replacing the VGM Board
Carefully slide the VGM Board under the cables that
cross its path.
Position the VGM Board connector above J1. Make
sure the pins at J1 on the Engine Board line up correctly
with the connector on the VGM Board. Carefully insert
the board into position.
Replace the bracket.
Fold the shield back into place. Install the 5 Phillips
head screws at the rear panel edge.
Verify that all cables going to and from the Engine
Board are still secure.
