The DEUNA/DELUA is possible to stick in there. Jonny Eriksson was
working on support, but it was more than a memory limitation issue. The
DEUNA/DELUA was never design with the 18-bit transfers in mind. But as
far as I know, he got IP and UDP running over ethernet on a KS with
Tops-10.
Found a relevant thread:

Seems MRC did the Phase IV for TOPS-20 on KS, but no ethernet. bygg did
ethernet for KS but only for IP under Tops-10. Some hints and hooks seem
to have existed for ethernet, but no code seem to actually have existed.

So no
just sticking a DEUNA board set in that BA11-K?
It's a long story. The hardware (a DEUNA in the 2020 UBA/UNIBUS
box) will work, but the software never supported it. It was mostly a
memory issue. The KS10 is limited to 512KW of physical memory and
space is very tight on the 2020. Supposedly Mark Crispin had Ethernet working
with TOPS20 on his
2020, but that was never released as a product and the status of that
software today is, I think, unknown.
That is something I don't think I ever heard. But maybe I just missed
it. But I seem to remember that MRC worked on Phase IV for KS, and got
that working. But not using ethernet as far as I know. But I really
should try to find where that was discussed. Should be available online
somewhere...
