means that multiple applications carry multiple copies of such code. Some DOS
development systems allow applications to share code, but that is the exception.

PCMCIA Card Considerations

PCMCIA cards can be used to provide additional storage space for applications and data.
PCMCIA cards recommended for use on the PDT 7200 include:
• SRAM with FAT format, using CardSoft™
• non-ATA (Native) flash with FAT format, using CardSoft
• ATA flash using CardSoft.
The features of various types of PCMCIA storage cards are summarized in

ATA) Flash

* On PDT 7200 terminal.
** Native (non-ATA) flash cards can be written on some systems (en-masse) but cannot be
updated file-by-file on any system (if FAT-formatted) and cannot be written to on a PDT 7200 at
all.

Power Use
Very Low Read/Write Static Ram. Low-power
CMOS with backup battery. Rugged.
Very Low Read-only flash which emulates a
disk drive, but has no smart logic to
allow file-by-file write. Rugged.
Medium Read/write capability, has smart logic
to emulate disk drive. Less expensive
than SRAM. Higher power
consumption than SRAM. Rugged.
