TYhe Second Sight performs various functions, including an Apple II/IIgs video 
to VGA converter (this is how most Second Sight owners use their card).

The nice thing about the Second Sight is that if you don't like the RGB 
display is generated, you can write your software code to make it do something 
different.  You don't have to burn your ROM--just write a driver when the OS 
boots.  Jut because nobody has done this doesn't mean that it doesn't have the 
capability.  It becomes really easy to support enhancements when no hardware 
changes are needed.

If you want to immediately make HGR look horrible by adding NTSC artifacts, 
there is nothing to prevent you :)
