A cartridge interface retains and couples a first information device, such as
PCMCIA
type card, with an internal connector of a host computer used in a rugged environment.
It may also retain a second information device, such as a memory drive, separate
from the first information device. The host computer has a cartridge insertion
slot that guides the cartridge and a connector of the PCMCIA card into engagement
with the computer's internal connector. The PCMCIA card is retained on the cartridge
in a manner that prevents translation of the card relative to the cartridge during
removal from the host computer.
