Attaching SCSI Devices to Your Computer
Some Power Mac G4 computer configurations come with an Ultra160 Dual Channel SCSI
card installed in a PCI slot with one or more internal SCSI hard disks connected to it. You
can install additional internal SCSI hard disk drives, up to a maximum of three drives. It’s
recommended that you only connect SCSI Ultra160 LVD hard disk drives to the internal port
of the Dual Channel SCSI card. You can connect external SCSI devices, including older drives
with slower data transfer rates, to the external port of the Ultra160 Dual Channel SCSI card.
Because the card has two channels, one connected to the internal port and another
connected to the external port, connecting older devices to the external port doesn’t slow
down the transfer rate of the internal hard disk drives.
Apple recommends that you use only SCSI Ultra160 LVD devices as internal hard disk drives.
To connect older SCSI devices that use a 25-pin or a 50-pin connector—such as Zip drives,
scanners, or DAT drives—you need to purchase SCSI adapters, or purchase and install an
additional “legacy” SCSI PCI card (one that supports older devices).

Transferring Information Between Two Macintosh
Computers
If two Macintosh computers are not connected by a network, you can transfer information
between them by connecting them with a standard category 5, 4 wire-pair (8 wires) Ethernet
cable (in effect creating a small network of just two computers), which you can buy from an
Apple-authorized dealer. You connect the cable to each computer’s Ethernet port and then
turn on file sharing on both computers. You can also configure the Ethernet settings on two
computers to create a small network.
First, turn on file sharing on both computers:
1 Choose System Preferences from the Apple (K) menu.
2 Open the Sharing pane.
3 Click Start to turn File Sharing on.
Next, follow these steps on one computer:
1 Choose Connect to Server from the Go menu.
2 Click Local Network.
3 Select the computer you want to access.
For more information about configuring Ethernet connections, search for “Ethernet” in
Mac Help.
