I would say that there was a standard.  Sun made narrow-diff
SBUS cards, I believe Interphase made VME n-d cards.
Some of the first RAID boxes I dealt with were n-d, and
I have seen Seagate Elite 3 drives that were n-d, the ST43400ND.

 Was there a narrow differential standard for SCSI?  I've never seen narrow
 differential.
