Centurion PC was designed for the a customer requiring Pentium class
performance in a rugged box drawing automobile voltage. The chassis
was based on the Challenger PC. The
system contained a high specification littleboard VNS-686 (now end
of life), laptop hard disk, PC/104 based DC to DC converter HE-104 and some custom PCB's.
The main differences were the increase in chassis height which was
required to incorporate a PC/104 based DC-DC converter which allowed
the chassis to be operated in a military vehicle and two additional
PC/104 cards (for future expansion). The dimensions of the chassis
are 240mm * 260mm * 108mm. A wealth of I/O was brought out at the
rear including 4 serial ports, vga, composite video, floppy, ps/2
keyboard, ps/2 mouse, 100 Base-T Ethernet and matrix keyboard interface.
