	5) As I understand it, the color palatte of the IBM CGA
	standard is really limited to 8 colors with 2 intensities of
	each.  On the other hand, the EGA standard allows for a "64
	color palatte".  Which 64 colors?  2 bits per primary?

Yes indeed, the EGA works with 6 TTL lines, two for RED, two for GREEN
and two for BLUE. These are converted inside the monitor into intensities.
This gives you 4*4*4=64 colors. These colors are adressed via 16
palette registers, so you can use 16 out of 64 colors in one frame.
