Sure... Just one more example of PMR! :-)

If the node
you were on was in a hidden area then you had to do your
own "routing"
of sorts to get the areas outside your facility.
As an example: If I was on node FOO::, and FOO:: was in a hidden
area, and I wanted to send email to another site on node BAR:: then
the DECnet path might look something like this:
ROUTR1::BAR::<username>. Where ROUTR1:: is a non-hidden area node
within my facility.
If the other end had the same issue then the chosen path might look
something like:
ROUTR2::FOO::DAVIDSON. Where ROUTR2:: is a non-hidden area node
within the source facility.
This was referred to as PMR (Poor Mans Routing). The
concept was not
new because it had been used in previous versions of DECnet anyway,
the application was... Sort of... HECnet has reserved area 63 for
hidden area nodes - to play with mostly. I did some
playing around last year.
If I can ever find my notes (from DEC days) about the whole setup I
will get back to playing some more with it.

This sounds like it was a bad idea back then and a bad idea now. :)

Actually, it worked quite well! In my group most people that had
hidden area nodes also had accounts on non-hidden area clusters so most
of their email was fine. In fact, cluster aliases had to be non-hidden
so it all just worked out.
I remember using "mail", "phone", and "notes" without issues.

What exactly does that mean?
I just too a look at the NCP sources. It appears that that message is
returned when several $QIOs fail. Sadly, the code masks the $QIO(W)'s
return status and anything in the $QIO(W)'s IOSB.
Perhaps, if you can describe what you were doing when you reveived the
error, the cause can be narrowed down.

Wouldn't it be ironic if Hecnet ran out of addresses :)
Does anyone know what the largest DECnet deplayment was
duing the good old days?
The internal net at DEC was seriously out of addresses,
though just
like IP that's partly because the addressing scheme forced
it to be
somewhat sparse. Still, there were certainly tens of thousands of
nodes on it.

And let's not forget the hidden areas that DEC was forced to go
to...
Hidden areas? ;)

that were in areas 61-63 that could not be seen beyond that facility.

My DTC01s and DTC03s can *speak" many many different things too! ;)
