Mr. Wicks,

    You're wrong wrong wrong about amiga graphics modes (although I
wish you were right.)  The following are the supported modes on the
standard denise: (Please, someone ELSE please correct ME if I'm wrong).

   320 x 200    32 colors/4096 colors
   320 x 400    32 colors/4096 colors     interlaced
   320 x 200    64 colors/4096 colors     extra_halfbrite
   320 x 400    64 colors/4096 colors     interlaced extra_halfbrite
   320 x 200  4096 colors/4096 colors     HAM
   320 x 400  4096 colors/4096 colors     interlaced HAM
   640 x 200    16 colors/4096 colors     hires
   640 x 400    16 colors/4096 colors     interlaced hires

Any of these modes may be overscanned.

The ECS supposedly supports the following additional modes:

   640 x 480     4 colors/64 colors       productivity mode (Multisyncs)
   640 x 960     4 colors/64 colors       interlaced productivity mode
  1280 x 200     4 colors/64 colors       super hires
  1280 x 400     4 colors/64 colors       interlaced superhires

  1280 x 480     1 color/64 colors ???????????
  1280 x 960     1 color/64 colors ???????????

My question is, why the limitation of color selection to 64 colors?
Is it possible that a future denise may incorporate more
bitplanes/colors?
Why not go straight to that denise?
