Apple 640 manual Expanding memory, Replacing internal storage devices

Expanding memory

You can install additional random-access memory (RAM) in your computer, which allows you to work with more programs and larger documents. Additional memory comes on memory modules (also called SIMMs). The Technical Information booklet that came with your computer describes how much additional memory can be installed in your Macintosh.

You can also add up to 32 megabytes (MB) of RAM for use exclusively in the PC environment. See Appendix B, “Installing an Expansion Card or Memory for the PC Environment,” for further information.

WARNING To avoid damage to your computer, Apple recommends that only an Apple-certified technician install additional RAM. Consult the service and support information that came with your computer for instructions on how to contact an Apple-authorized service provider or Apple for service. If you attempt to install additional RAM yourself, any damage you may cause to your equipment will not be covered by the limited warranty on your computer. See an Apple-authorized dealer or service provider for information about this or any other warranty question.

Replacing internal storage devices

Your Macintosh comes with three internal storage devices—a floppy disk drive, a CD-ROM (compact disc read-only memory) drive, and a hard disk drive (several capacities are available). If you want to replace your internal drive, see your Apple-authorized dealer.
