	Well, actually, I didn't comment on software support for different
configurations, I commented on the flexibility of the Amiga's video hardware.
Specifically, the fact that the DMA channel structure is not static like in
the ST, and can dynamically distribute the 14Mhz of bandwidth between the
many different VLSI chips requiring DMA (video display & sprites, processor,
blitter, sound channels, disk, and co-processor).  Did I miss anything?
