Ah, but what they don't tell you is that all 4 Meg, and any expansion
memory, is the equivelent of the Amiga's Chip Ram.  Sounds good, until
you realize that the video eats half of the memory bandwidth, apparently
regardless of video mode.  The memory is given to video for 250 ns, and
then to the CPU for 250 ns.  With a 68030, that could significantly eat
into the throughput on anything that doesn't run in cache.
