Expanding memory
The random-access memory (RAM) in your computer can be expanded by
adding Single Inline Memory Modules (SIMMs) to those already installed or
by exchanging installed modules for ones that have greater storage capacity.
In the Power Macintosh 8100/80, the memory used to display images on the
screen (called video RAM, or VRAM) can also be expanded. In the
810 0 /8 0
AV , VRAM cannot be expanded.
Make sure that SIMMs you purchase for memory expansion are the correct
ones for your Macintosh. SIMMs for your model of Macintosh must be
installed in pairs of the same size into paired slots. See the Te c h n i c al
Information booklet for details.
Installing other internal devices
Your Macintosh holds up to three internal storage devices, including a floppy
disk drive, a CD-ROM drive, and a hard disk drive (several capacities are
available). See your Apple-authorized dealer for information about adding
internal equipment to your Macintosh.
WARNING
Apple recommends that additional memory on the main
circuit board should be installed by an Apple-authorized service
provider or technician. Modification of the circuit board by anyone
except a qualified technician voids your warranty and could damage
your computer.
