Apple Macintosh 6500 - Manual (Page 211)

m If the card does not have a hook, simply pass the external connector
through the opening in the vertical plate as shown. (Some cards have an
external connector that protrudes through the opening; others, like the one
shown here, have a flatter external connector.) Insert the card into the
communication slot. Press down on the card until the connector is solidly
in place.
Don’t force the card. If you meet resistance, pull it out and try again.
5 To see if the card is properly connected, lift it gently. If it resists and stays in place,
it’s connected.
Note: After you have finished these installation instructions and turned on
your computer, you may need to install software for your communication
card. If you installed an Ethernet card, you may also need to change the
network connection in the AppleTalk control panel. See both the manual
that came with the card and Chapter 7, “Connecting Your Computer to a
Network” for more information.
6 If you have DIMMs or a High Performance Module to install, go to those instructions next
in this appendix. If you are finished installing items, proceed to “Closing the Computer.”
