I am looking into getting a NUBUS board for a MacIIcx that
does DMA control for all SCSI I/O. I have seen a least one ad for
a DMA board, but I can't seem to locate it now.
Can anyone who has any info on a SCSI DMA board for Macs, reply
with some info that will point me in the right direction. Hopefully
I can find something that is compatible with A/UX 2.0.

There is much confusion over what makes a SCSI-2 drive. I can't say that I know, either- every manufacturer makes different claims. Some say, for example, that the new cable header must be used for a drive to be SCSI-2. I don't know if that's true, but I have seen other drives called "SCSI-2" which use the old style plugs... In the end it doesn't matter. For now MicroNet will only sell the board as part of a disk subsystem. I can't say that I blame them- it prevents them from getting blamed for other people's problems- although I might wish it were possible to buy them separately... So for now, you can only get them with Wrens, because that's what they get sold with. And in that configuration, they are indeed very very fast. As for A/UX, the drivers are still not available. --- Alexis Rosen Owner/Sysadmin, PANIX Public Access Unix, NY {cmcl2,apple}!panix!alexis
