=== Restoring mouse eject ===

When an Apple 3.5 mechanism is installed in an 800K drive, holding down the mouse button during startup no longer ejects a disk. Apple's fix:<ref name="ss800" />

# Remove the bottom cover and the interface cable.
# Orient the cable connector as shown in the manual. Locate the last wire on the left side in the lower row; the pin above it is empty.
# On the underside, locate the spring clip under that wire.
# Push in the spring clip and gently pull the wire out.
# Wrap the connector end of the wire in electrical tape so it cannot make contact.
