Note, however, that a Y/C approach still leaves you with low-bandwidth
chroma, which means that single-pixel vertical details that have the
same luminance but differ only in chroma will not be well resolved.
Yes, I imagine so, but I'm not sure how this will play out in reality
yet. In the worst case of IIgs 640x200, if the max Y bandwidth will
be 8mhz, I'm guessing that the max C bandwidth here will be 3.5mhz.
I'm easing up on the bandpass filtering quite a bit. So depending on
the monitor, there might be either very fine vertical lines some with
color and some not, or with a lower res monitor, we might get
acceptable results.
