Expanding memory
The random-access memory (RAM) in your computer can be expanded.
Installing additional RAM adds more memory chips to your computer and
expands its capabilities. The Technical Information booklet that came with
your computer describes how much additional memory can be installed in
your Macintosh.
Memory for your computer is provided in packages called Single Inline
Memory Modules (SIMMs). The SIMMs must be the correct type for your
computer and should be installed in pairs of the same size into paired slots.
It is very important that the SIMMs be correctly installed in your Macintosh.
Incorrect installation can result in errors, unpredictable results, and damage
to your equipment and data.
Installing internal drives
Your Macintosh can hold up to three internal storage devices, including a
floppy disk drive, a CD-ROM (compact disc read-only memory) drive, and
a hard disk drive (several capacities are available). These drives may already
be installed. If you want to add or replace an internal drive, see your Apple-
authorized dealer.
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.
