Prepare the Upgrade and Logic Boards for Installation
Note The following steps explain how to prepare the logic board to accept the upgrade board. Caution The EMI clips on the bottom of the logic board are fragile. Do not apply heavy pressure directly to these clips or you may bend the logic board. Place a piece of antistatic foam directly under the processor socket on the bottom side of the logic board. Note This step helps prevent the logic board from bending when you apply pressure in the next few steps. 2 Lift and rotate the battery one...

Processor on the Upgrade Board
1 Note The alignment corner of the 68LC040 processor is missing one pin. The alignment corner of the spacer is missing a pin hole. 2 Position the spacer alignment corner over the 68LC040 processor alignment corner 3 Place the spacer on the processor. Caution Forcing the 68LC040 processor connector pins into the socket could damage the pins. If the processor resists installation, check the pin alignment. Caution Place the upgrade board on a firm even surface to avoid bending the upgrade board...

Replacement Note In
rerouting the cables, do not crimp cables between the harness and the floor or sides of the bottom case. Route the speaker cable between the logic board connector and the CD-ROM shelf. Route the fan, power supply, and header cables to the side of the front panel control bay. Replacement Note Arrange the cables as shown before replacing the shield wiring harness. When dressing the cables, do not crimp them between the harness and the floor of the bottom case, or between the harness and the sides...
