Portable Computer with PCMCIA Card Expansion Capability

      Described is a portable personal computer system including a
planar board, a lower cover, and means for providing additional
system features by installing a number of standard card and socket
assemblies, as defined by Personal Computer Memory Card International
Association (PCMCIA) standards, within a space between the lower
cover and the frame.

      The Figure is an exploded view showing major components
providing this feature.  A planar board 10 is installed within a
lower cover 12, with an opening 14 within the cover providing
physical access to a space between the planar board and the cover.
This opening 14 may be covered by a removable door (not shown).

      A PCMCIA-type expansion card 16 is plugged into socket assembly
18, with a number of electrical connections being made along an edge
of the expansion card through pins extending from the socket assembly
into receptacles in the expansion card.  Socket assembly 18 also
includes a pair of rails 20 along which the card is slid into
engagement with the socket.  Generally, each socket assembly 18
includes mechanical provisions and independent electrical connections
for two expansion cards 16.

      PCMCIA-type cards are made in a number of types, providing such
functions as radio interfaces, Radio Frequency Local Area Networks
(RF LANs) hardfiles, and additional memory.  Several sizes of cards
of this kind are available, differing in t...
