OK, I see -- you mean if you take the Coco's 200 lines as they are, without 
doubling them up to 400 lines.  I'm afraid that if you do that, the view will 
be not only "letterboxed" but also squashed, since the Coco's native pixels are 
twice as tall as they are wide, while the VGA screen's pixels are square.

I think the line doubling, however you do it, is necessary for proper 
proportions of objects on the screen.  --Mike K.
