It is my understanding that the blitter is merely a DMA device that will
move chunks around and optionally perform one of a few logical operations
on it.  The Am29k in the new Mac graphics board is a RISC CPU which is
dedicated to speeding Mac graphics.  It is closer in function to the Amiga
chipset but is still one level above it.

It is similar in function to the TI34010 boards for the PC series, simply
a graphics engine.

BTW, what ever happened to that Really Cool graphics board from England?
Does anyone have one?
