You can do it in its MCGA mode (the 320 x 200 256 color mode) and its higher
resolution modes that have fewer colors.  I did a program that used the MCGA
mode on the model 60 and it worked just fine (and it was very easy to write
because the library routines are extremely simple).

There are two caveats though, you must have either version 5.0 or Quick C (the
real documentation for the graphics routines are in chapter 4 of the Quick C
manual, fortunately that comes with 5.0 also).  The other caveat is that you
can forget using any of the fancier modes on the new Super VGA cards with the 
Microsoft library, if you want to use those you'll just have to get down and 
dirty.  However, this shortcoming probably affects the Turbo libraries also :-(
