Adding memory to your computer

Your Macintosh PowerBook comes with at least 12 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 Appendix C.

Your Macintosh PowerBook also supports virtual memory, a feature that

makes use of hard disk space to provide additional RAM. Your computer was

developed to take advantage of the virtual memory feature and comes with

virtual memory turned on.

For information on using virtual memory, see the “Memory” topic area of

Mac OS Guide, available in the Guide (h) menu.

Using infrared file transfer

Your Macintosh PowerBook has a built-in infrared (IR) window that can send

and receive files. You can exchange information with another PowerBook that

has IR capability or with a desktop computer that’s using an external IR

module.

To transfer files, your computer and the other IR device must be within 3 feet

of each other, with their IR windows facing. You use the Apple IR File

Exchange program, on your computer’s hard disk, to send and receive files.

Complete instructions for using the software are provided in the Apple IR File

Exchange Guide (available in the Guide [h] menu when IR software is the

active application).
