Jim,

   HAM-E does use 640 x 200/400I screen.  Remember, to get 16 colors, you
need 4 bitplanes (2^4 = 16).  By taking adjoining pixels together for a 320
x 200/400I screen, you get two columns of 4-bits => 8 bits/pixel => 2^8, or
256 simultaneously displayable colors with no restrictions.  


I'm still a little confused about the new HAM thing, though.
