The warnings about "we'll soon de-support
the DEQNA"
started in release notes round about 1987. It lasted
for at least another five years.
Ethernet drivers used to use an interface called FFI
- allegedly Flaming Fast Interface but that was presumably
just for management consumption :-)
Round about V5.4[-x] or V5.5[-x] this interface
was replaced with a new shinier one (whose
name I've either forgotten or never knew) and
at that point the DEQNA was stated to have stopped
working. I never actually tested this, but the DECnet
folks (in whose group I was working) told me
it just plain would not work - by design.
As someone that had a couple of DEQNAs in a MVII, I know
from experience that V5.5 absolutely refused to work
with
them. We bought a couple of DELQAs (we got the Turbo,
in fact) in the trade-in offered at the time.
