Thanks a lot for posting that, looks like I'll have to use the 4000T or get an A4091. Shame that it won't work with a Deneb...
Well, in an A4000T with onboard SCSI running you won't get
any Zorro III DMA card running.
The problems with several masters on Buster 9 are known, and can be avoided, as seen in FastLane Z3 and DENEB running simultanously.
Unfortunately Commodore messed it up in the A4091 and released the Buster 11 as "hot fix", which works only with one Zorro III master.
