   on most cga type systems, the second 8 colors (9-16) are half-
intensity versions of the first 8 colors.   there is a good chance
that the amdek monitor does not support the intensity signal on
the card's rgb interface.  then again the tga board may not emulate
a cga board much, which makes cga information not applicable.

the microsoft basic compiler (version 7.0) supports modes
0 through 13.

Version 2 of anything is usually the version that works.
