VLB SCSI?

Not having tried it I can't say, but there's clearly a difference in performance
between a 32-bit slot and 64-bit slot. I'd guess the fast I/O devices need all
the transfer bandwidth the 64-bit slot can offer. That would make a 64-bit
board plugged into a 32-bit slot inappropriate if not useless.

Surely somebody is making and selling these things.
