PCMCIA Memory Card 3
The processor includes 4 MB of on-board memory that can be erased and
overwritten many times. A PCMCIA memory card can be used to install or
upgrade the system software into this memory. A memory card can also be used
to back up and restore system programming.
There are different types of memory cards, each about the size of a credit card.
Their labels indicate contents and function. Described below are three types of
PCMCIA memory cards that you may encounter. For more information, see
System Programming
