Something which doesn't necessarily have to shine through in the user/OS
interface. In this case, it's not due to the inner workings of SCSI, but
rather the PC philosophy.

We sold ours. It worked, but was wasted on our SCSI setup after our last SCSI
drive died.

IBM had two 30-pin slots on their MCA SCSI cards.

I like my Fastlane Z3 card. It's about the fastest Zorro3 SCSI card one might
get, and it's got sixteen 30-pin SIMM slots for system memory expansion as
well. =)

I've not had much problem with cables. If a cable doesn't work, it's quite
obvious, and I replace it.
My DECstation runs with an HP cable now, and it works fine. A good testament
to the marriage between the two companies. =)
