I have not yet found exactly the right manual for the DEBNI but
I think I remember seeing some stuff buried in some other
manual.

The XMI Adapters handbook has a bunch of useful XMI stuff.

EK-640EB-MG (VAX 6000-400 Options and Maintenance) has a bunch
of other useful stuff.

EK-640EB-TM (VAX 6000-400 Technical User's Guide) has even more stuff.

The DEBNI installation guide has some sparse register documentation,
but not a great deal of it.

I'm not sure that all of these made it to Manx so if
you cannot find any of them, give me a shout and
I'll put them up for FTP (and try and get them to Manx).

My recollention is that the orignal DEBNA tried to be both
a TK50 (TK70?) controller and an ethernet controller and was
somewhat unsuccessful in one or both roles! The functionality
was then split out into two cards. Quite how these cards
relate to the original DEBNA is something I've forgotten.
But if you come across DEBNA info it will probably help
with the DEBNI.
