I have the non-cahce IBM adapter. The only thing "non-standar" that I
saw was the smaller connector (external). Non-IBM cables are available,
I saw a few at Comdex. I was told it's the same as the RS/6000 external
SCSI connector.

As far as set-up, it was plug-n-play for me. I set NOTHING. The controller
found the drive, and when I added a SECOND drive, and a tape, I just set
the SCSI ID on the new drive and tape, and re-ran the reference disk.

I highly recomend the IBM controller (assuming comparable pricing.)
