It is indeed.

That's what the special backplane wiring and the KTJ11-B Unibus
adapter take care of.

Hi Again All:
In the same trip to the scrap place I bought an M7792 DEUNA card. From the
DEC Field Guide it's unclear whether this card is usable by itself, or
needs a companion card M7793, to bring Ethernet connectivity to a Unibus
machine.
Anybosy know anything further? I'd like to have Ethernet on my 11/45 once
I solve its (probable) power supply problem.
Thanks,
Kevin

I'm almost embarassed to say: I believe it was a site that compared
PCs and Macs. If it was a ruse, it was very sophisticated for a
person who writes an 'intelligent comparison' of PCs and Macs. Maybe
they were paid off by you-know-who ...

Without any rev letters after the M8190, what you've got is
almost certainly the old 15MHz non-FPA-capable KDJ11B. Probably
very similar to the CPU in the Micro-11/73 you got from SERF at UBC.
(Or, at least I think like the Micro-11/73 I seem to recall you
getting from SERF. There was a Micro-11/23 and a KA650 in a BA23
I also seem to recall...)

You also need the M7793, in addition to a DEUNA cab kit.
If you get a chance, grab the DELUA instead - it's a single-board Unibus
Ethernet adapter.
