Very true that MacOS never utilized the IIfx to its potential. But AFAIK
it did NOT have DMA. It had extra processors which took care of things,
so all the CPU had to do was copy data to and from IOP buffers (which
can just be a memory copy loop; VERY fast).

Wasn't that back when MacWarehouse and friends put their whole catalogs
inside the magazine? :-)

Take care,
