Makes perfect sense, there's no SCSI DMA over the Zorro bus (just to onboard RAM) so why would the DENEB be affected?
Wouldn't this also be the case with the A4000T (NCR motherboard SCSI)?
The Deneb should work in ZIII DMA in A3000 with Rev 9 or Rev 11 Buster chip. Of course you have to have the denebdmausb in the flashrom.
And assuming you have no other Zorro 3 DMA cards like a FastLane Z3.
