   I wonder how much does it cost, and how many units I would sell 
on the amiga platform.  Take for instance how many people here thinks
a 256 color card at 1200$ is overpriced, and doesn't fit on an A500 :-). 

   On a side note, uses of 108 bitplanes on a 1024 * 1024 eats 
over 14meg of video memory.  It can become costly, especially if
you want to adress and perform special operations while displaying
(need faster chips, prices goes up)
