What greyscale means on the TI is that you have two bitplanes that
are swapped at each VBL interrupt. This is only possible because it is a
slow display. You simply have to bitplanes. And where you want a black
pixel you set both bitplanes to 1 and where you want a grey pixel you set
only on of the bitplanes to 1.
