Allegro CX Owner’s Manual 59
PCMCIA stands for the Personal Computer Memory Card International
Association. This association has developed standards for PC cards.
PC cards are about the size of a credit card and come in three types
or thickness.
The PC card slot accepts Type I or Type II cards. These cards include
ATA Flash Cards, SRAM (Static Random Access Memory), and
Compact Flash cards. All types of cards have a 68 pin connector for
attachment to the Allegro. The cards must be 5 V or 5 V/ 3 V (PC
cards that are 3 V only are not supported). This is a 16 bit card slot. It
is not a “card bus” slot.
A PC memory card is a solid state, self-contained memory board
housed in a credit card-sized package. These cards behave like hard
drives. You can read from them, write to them, and erase single fi les
from them. There are several types and brands of cards available.
ATA Flash Cards
ATA Flash cards provide solid state data storage. Power is not
required to maintain the data. The Allegro accepts cards ranging in
size from 64 M to 100+ M, with larger cards available.
Compact Flash Adapter Cards
Compact Flash cards provide solid state data storage. Power is not
required to maintain the data. The Allegro accepts cards ranging in
size from 64 M to 100+ M, with larger cards available.
An adapter is required to use a Compact Flash card. Slide the
compact fl ash card into the adapter then insert the adapter card into
the card slot behind the display of the Allegro as described under the
Inserting Cards heading in the PC Cards section of Chapter 2.
SRAM Cards
SRAM cards provide solid state data storage. Power is required to
maintain the data. The Allegro accepts cards ranging in size from 1
M to 64 M.
