There is indeed a large PGA chip (same size as the i860) right next to
the VRAM with the telltale Bt logo on it.  Unfortunately the picture
does not have the resolution to discern the numbers (maybe if I take
it to JPL, they can enhance the image).  I don't really see how a color
map would fit into PostScript, but it must be available at a lower level
for fine-tuning a monitor's color.
