IIRC dac960 has completely OS-independent firmware and communicates
using some kind of protocol? with host os - it is only a storage
controller with SCSI pass-thru for SCSI Tape. It's not what you'd call
a SCSI HBA :)

I wouldn't be surprised if dac960 isn't somehow similar to DPT EATA
standard, where you didn't give a damn about integrated firmware (DPT
Smart* IV controllers used m68k cpu's connected with specialised SCSI
co-processor and PCI bus adapter - It's firmware was completely
independent (most powerful models had complete 68060 :D)

I don't think it's necessary to have a bus analyzer.... just read SCSI
documentation and available source code from *BSD and Linux...
