Memory Cards
Memory Cards can be used to store data or programs as files to expand the
memory
storing
capacity of the PC. Memory Cards fit into the slot located on the
lower
left side of the CPU. Memory Cards are not provided with the PC and must
be ordered separately and installed in the CPU. There are three types of
Memory Cards that can be used for the CV-series PCs: RAM, EEPROM, or
EPROM.
