I think what people want mostly is a card to take the 
Apple II modes and display them on a VGA monitor. Yes, 
a full-featured VGA card would be nice, but what say we 
get a converter card just to display the Apple screens 
onto the VGA monitor for now. Add a connector so you 
can create a daughtercard later and install the VGA modes 
to it at a later time.  :o)
