Does anyone know any software that supports this Tandy 1000 4-colour resolution?
Or perhaps, BGI driver is available.
Most notable is Windows 1 and 2 (technically 3.0 real mode) had 640x200 4 color support.
Others that do (typically for 640x200x4 composite color some PCJr only)
ColorPaint: A PCjr-specific paint program (see Brutman.Com)
Microsoft Flight Simulator (versions 2.xx): Offered the high-resolution 16-color low resolution mode in addition to 320x200 4-color.
Blue Angels and Indianapolis 500: Games that specifically support Tandy composite color graphics.
Sargon V: While also supporting EGA, it offered different color palettes for Tandy/PCjr
Various iterations of Tandy DeskMate and any programs that use it as their runtime environment.
