AFAIR, the TT can do SCSI DMA to TT-RAM, but floppy, ACSI and video are limited 
to ST-RAM.

On the Falcon, there are extension boards like the Magnum F030 that add TT-RAM 
below 16MB (the original CPU has only 23 address lines). AFAIR, those can do 
SCSI DMA too. However, I suspect that anything above 16MB (which can only be 
handled by a CPU on the accelerator card) will not be DMA-capable.
