I have a Tandy 1000TX which has the standard Tandy Graphics Adaptor.
Everything I have read implies (no, states) that the TGA can display
up to 16 different colors at simple resolution (is that 320 x 200, or
something?, I forget).  I have mine plugged into an Amdek RGB monitor
(circa 1985), and have only ever seen 8 colors; both in programs that
allow you to select the foreground/background colors, and in that
basic color program that comes in IBM-DOS.

Has anybody else experienced this (colors 9 thru 16 are just a repeat
of colors 1 thru 8)?

Is it because of the monitor (perhaps it is limited to only 8 colors,
or perhaps there is something I need to adjust--no apparent knobs to
turn)?

Is it because of the TGA?

Is there a program I can load on start-up?


Thanks,
mdp
