   Several months ago, I brought up the idea of enhancing the Janus 
software to allow the A2410 to emulate an SVGA card whenever the A2410
is used on an Amiga in conjunction with a BridgeBoard.  This would 
allow the A2410 to be used for more than just UNIX.  Unfortunately,
I have know idea whether or not Commodore is working on this because
they are obviously not talking.

   I do not think any of the other video products would be very 
satisfactory in emulating an SVGA card.  The reason is that all of the
graphics-enhancement boards available for the Amiga -- except for the
A2410 -- flicker horribly.  SVGA cards are not used for video work,
so to emulate one requires a flicker-free display, with none of these
video cards offer.
