PC in a folding case may be built using SMT ICs.
An elastomer keyboard would be used, folding in 3 sections, giving
the same key placement as existing PCs.
is a supertwist LCD display, requiring low power to
operate and maintain. A 640 x 480 configuration is within present
technology, giving an aspect ratio similar to standard VGA CRT
is provided by silver oxide cells, supplemented by
silicon photocells surrounding the display, which are exposed when
the unit is opened for use.
System (OS) is in ROM. Boot-up takes
application of power to the system. The OS is compatible with
present versions of DOS and OS/2 (Standard Edition).
replaced with up to 2 megabytes of CMOS VDISK, and
connectors are provided for attachment to an outboard (separately
powered) hard disk and other standard I/O. The VDISK is maintained
with silver oxide cells.
A serial I/O
connector is provided to allow data transfer and
communication with outside systems.
