	Has anyone noticed something funny with the specs for the
NeXTStation Color?  My copy of the progaganda says that the machine
has 1.5 Megabytes of VRAM for the display.  However, this does not appear
to be enough considering the following specs on the display itself:

	16 bits per pixel
	1120 pixel horizontal res
	832  pixel vertical res

Thus, 2(bytes) * 1120 * 832 = 1820 Kbytes ~= 1.777 Mbytes

	Is system ram used for the display as well?  Or perhaps only
the color bits are kept in VRAM...

Thus, 1.5(bytes) * 1120 * 832 = 1365 Kbytes ~= 1.333 Mbytes

This seems an odd way to do things, but I can't think of
any other even semi-reasonable explanation (other than
I've forgotten how to multiply).  :^)

	Does anyone have suggestions, perhaps based on more than
just idle speculations like mine?
