VGA cards and clones, including 600x800 ones, will only display 
a 64 level gray scale. This is because the DAC's are only 6 bit.

HOWEVER, if you really need a 256 level gray scale it relatively easy
to make a cable that will convert 256 colors into 256 gray levels.
It just requires some hardware hasking abilities.
