Apple 6400 appendix Opening the computer

Opening the computer

IMPORTANT To avoid generating static electricity (from your body) that may damage components, do not walk around the room until you have completed the installation of the DIMM or High Performance Module and closed the computer. Additionally, move the logic board as little as possible while it is outside the computer case.

1Shut down your computer by choosing Shut Down from the Special menu.

You can also press the Power key (marked with a π) on the keyboard.

2Unplug all the cables except the power cord from the computer (including the cable that connects your keyboard to the computer).

Leaving the power cord plugged in helps protect the computer from electrostatic discharge damage. (You’ll unplug the power cord later.)

3With a screwdriver, remove the two screws shown here from the computer’s back panel.

Remove these two screws.

Do not remove this screw.

Leave the power cord plugged in for now. You’ll unplug it later.
