This doc will help a lot:
    3000-900_9000-800_OnlineDiagnosticsSubManual_VolIII_LAN-SCSI-MUX_09740-90034_324pages_Jul91.pdf

Look at Section 18 "SCSIPBA" - register descriptions starting on page
18-21. Register overview on 18-33 (page 216 of the PDF).

And I finally found the name of the SCSI chip in the above doc: SPIFI
(v3).  The "Fast-Wide HVD" NIO card uses SPIFI v4.

Knowing that name also helped find the Net BSD driver (again):

and looks like NetBSD "newsmips" did support SPIFI-3:

cheers,

ps. It's embarrassing I couldn't remember the name of the SCSI chip: I
worked on HPUX SPIFI-4 driver between 1994-1996.
