Why aren't there any dedicated-scsi chip/cards for the mac
which work? The idea is simple: you have a processor with
a large cache; in theory, writes to disk are handed-off
instantly from the cpu to the coprocessor. If the cache is
large enough, many types of reads could be nearly instantaneous
as well.

Why not?

I understand the new, nefarious Mac IIxi will have some
of this feature, but could someone enlighten me as to how
all this _REALLY_ works ???
