[HECnet] Effects of Rogue Duplicate HECnet Node?

That's interesting; I thought I recognized the format.  I wonder where 
in the world I could be remembering it from?  It is surely not parsed by 
either COMND% or GTJFN% and I don't believe Tops-20 NFT currently allows 
it.  However, I haven't really gotten into tinkering with NFT, yet.  I'm 
finishing up some changes to FAL and DAP and then I'm probably going to 
work with Johnny a bit to iron out some oddities in the email interface 
(SMTP DECnet and Tops-20 MAIL11).

I keep thinking about implementing rename in Tops-20 DAP, but I just 
stumbled over what appears to be a BLISS based implementation of FAL and 
DAP which MRC never seems to have put up.  Maybe it's great.

So what era does Ultrix 2.2 hail from?  I believe we had an early 
version, something like 1986 or 1987.  However, I doubt they put that 
syntax in and then took it out.  So do I understand that DECnet wouldn't 
have been available on Ultrix 1.x?  I can't remember what version we 
had, which is remarkable because I wrote the entire Id system for it 
(using Ingress).

We appreciated some aspects of Ultrix; as I recall, it had both System V 
and BSD functionality.  I used the System V semaphore interface to 
implement locking for the Id system.  That much I remember; wrapping the 
calls in routines called P(); and V(); (obviously).  Regretfully, this 
is the only Dutch I ever learned...

I thought Ultrix had DECnet and LAT at a very early date; at least I 
remember the sales droids trying to talk that up. However, if it didn't 
have it, then that wouldn't surprise me. The effect of the cancellation 
of the 36 bit line was nothing short of electrifying.  I think my 
favorite quote was Ralph Gorin, upon being promised something which 
paraphrased, went something like this, "You're asking us to jump out the 
window under the assurance that you will have a net ready before we hit 
the floor."
