Connecting to a network
Your computer has built-in AppleTalk networking software. This
software directly supports the LocalTalk cables you need to
connect your computer to the network. (If your computer has the
appropriate port or expansion card, AppleTalk also supports
Ethernet and Token Ring cables.)
1. Choose Shut Down from the Special menu.
2. Connect the LocalTalk cable to the printer port ([) on
the back of your computer.
If your computer has a combined printer/modem port,
connect the LocalTalk cable to that port.
See your network administrator or the documentation that
came with your cables if you need more information.
Turning on AppleTalk

connected it to a network, you need to make sure that
AppleTalk is turned on.
1. Choose Chooser from the Apple (K) menu.
