Apple PowerBook (Duo, 2300 Series) - Manual (Page 59)

Connecting a monitor
You can connect a monitor to the Duo Dock Plus or the Duo MiniDock. See
the manuals for the dock and the monitor for instructions.
Connecting other devices
For instructions on connecting a device not discussed in this chapter—for
example, an external input device or networking hardware—refer to the
manuals that came with the device.
Adding memory to your computer
Your PowerBook computer comes with at least 8 MB of RAM. You can
increase your computer’s memory by adding a RAM expansion card. You can
find out how much memory your computer has by choosing About This
Macintosh from the Apple (K) menu in the Finder.
You can purchase memory upgrades from Apple-authorized dealers. For
complete instructions on installing a RAM expansion card, see the
Technical Information booklet that came with your computer.
Your PowerBook computer also supports virtual memory, a feature that
makes use of hard disk space to provide additional RAM. (When the power
adapter is not plugged in, using virtual memory will reduce your battery life,
however.) For information on using virtual memory, see the “Memory” topic
area of Macintosh Guide, available in the Guide (h) menu.
