   Um, like "The Six Million Dollar Man", "we can rebuild him"   
      
   But why? The ATI GUP was a happening card for the time, but it smacks   
   into 1,024x768. How many current monitors go that small on the screen   
    >natively< ?   
      
   So the GUP might serve as a basis for a current adapter implementation,   
   but should it be replicated?
