As a member of a small R&D group, we developed simulated aircraft
avionics displays driven by IBM PC-based graphics systems.
The demonstration system consisted of two rack-mounted 486 class PCs,
two 6"x6" color CRTs, each with 1024x1024 pixel resolution,
a smaller monochrome CRT that displayed text-based interface menus,
various keypads, a joystick and a throttle. One PC ran the aero model
and the other PC contained two channels of XTAR graphics processor cards.
The joystick, throttle and keypads interfaced to the"aero" PC through
an I/O rack to convert the analog and discrete inputs into useful signals.
The "aero" PC then sent instrumentataion information to the "graphics"
PC to be rendered and displayed. The flight path information was also
sent to a Silicon Graphics workstation to fly an eyepoint through a
basic polygonal visual database to show the instruments correlated with
an out-the-window scene.
