However, the Unibus and Qbus controllers have totally different programming models, and
are not compatible at all. There is not the slightest bit of relationship between them.
Anyone thinking that a DEQNA is just a Qbus version of a DEUNA is just plain wrong. And
the same goes for the DELQA compared to the DELUA.
They are not even close.
Well, that's good to know. I'll have to stop misleading people. Many
apologies!
As far as I
can tell, the DELUA is the Unibus equivalent to the DELQA. In
general, if you swap a U for a Q in the name, that's what you're looking
for (which is why if there's something called a DELNA, I don't know what
it is, but the only picture purporting to be on I can see on Google looks
an awful lot like a DELQA to me).
Right, apart from the fact that there is not really anything "equivalent" about
them.
Aside from the 68K controlling them, which is obviously a red herring.
Speaking of:
can anyone guide me as to how I should go about installing
DECNET on RSX-11M (not plus) 4.6? I'm having a hard time figuring out
which (if any) of the available images online will work for that version.
The tape images seem a bit hard to come by, and I've periodically scoured
Google looking for anything. Part of the problem is that I'm not as
familiar with the DECNET versioning system relative to the RSX one, so I
don't know what's compatible with what.
Isn't the manuals around? Anyway, it's much more of a headache than under 11M.
You need to create various regions for DECnet to live in, and you need to figure the sizes
of these. Fiddly, but not really that hard if you know what you are doing and/or have the
documentation.
I just need to spend more time with it, I guess. Haven't had a lot of
that lately.
