I don't understand this comment.  There is nothing special about the video
memory.  The bitmap is just part of memory, restricted by the refresh hardware
to start on a 512 byte boundary.  What limits the video memory to 32k at
present is the addressing scheme in the refresh.  It strikes me as being
arbitrary and I hope there are hidden capabilities in that refresh circuitry
to support higher res.

Still can't believe "We are the World", even got NOMINATED.
