What this chip does is basically what the Amiga custom chip set has
done from the start: allow dynamic reloading of the color lookup table
as you display your image. Also, it has some builtin ALU's to do a
linear blend of the pixel color with the existing pixel color under
software direction. So whatcha got is a dynamic pallete like the Amiga
except the PC pallete is 256 out of 16M as apposed to 32 out of 4096.
A card could be built for the Amiga to utilize this chip but considering
it is a non-standard display format, it is an image hack (like SHAM and
dynamic Hi-Res), and the recent proliferation of frame buffer boards
with zillions of colors; I see little reason to do it.
