By the way, MOP, from an ethernet point of view, is neither LAT nor DECnet. MOP is its own protocols on ethernet. 0x6001 and 0x6002. But I believe they were defined as being a part of the DECnet suite anyway.
The MOP spec is one of the DECnet architecture specs. And in fact it relies on the DNA datalink layer and is controlled via the DNA management layer. Other than that, it's indeed separate -- doesn't use routing or NSP.
Paul, what do you mean by "relies on the DNA datalink layer"?
MOP either uses DDCMP, which is a point to point DNA datalink layer, or Ethernet (including the DEC-originated explicit packet length field) which is a multicast DNA datalink layer. Or FDDI, I suppose, which is another DNA datalink layer.
In the latter two cases it may not be all that obvious, because people tend to think of Ethernet and FDDI as international standards. And so they are -- but DNA adds more detail. The packet length field in DNA Ethernet protocols (MOP and routing) is something in the DNA Ethernet spec but not in the international standard.

Hello!
Clem, I (not speaking for Johnny, but speaking for myself and four
cats. Also responsible for the perennial problem surrounding Dave.)
would never heap stuff on you. I actually applaud your efforts. As for
the stuff that still fastens the Internet together, it is indeed a BBN
solution. In fact in Cliff Stoll's book he mentions that bit of trivia
and also what to expect from them.
However he does complain as to how the routing of the Internet works.......

The annoying things here is that no information of this can be found. I'd be happy if you can help me with some references and pointers.

Well defined? RFC 791, which *is* the definition of IP is dated September 1981.
The predecessor, RFC 760, which is slightly incompatible with 791, is from January 1980. (For example, ICMP didn't exist then, instead you had IP options that were used to indicate errors.)
What specifications did you use for a TCP/IP implementation that you had running in 1979? And I'd say that any such implementation would work very badly, if at all, with any TCP/IP based on RFC 791.
FYI: the original IP/TCP for 4.1BSD was not written at Berkeley, it was

I assume you mean Rob Guruwitz. This TCP/IP implementation became "live" 18 Nov 1981, with a more general distribution planned for 1982.
(See RFC 801, page 18)
That RFC is also a good reference for the status of various TCP/IP implementation at the time (November 1981), and many implementations are still in development, and many based on each other.

Stettner, and the whole "TIG" (telephone industries group) in Merrimack

Not trying to come down on you, but "I was there" and very much "mixed

I know. You keep pointing that out. And I still can't reconcile your statements with all the published information that is around. (Nor can I find your name anywhere in those places I look.) So I'd like to find better sources of information than the RFCs, if you please could share them.
As for when MOP was released for the UNIX flavors, I really can not

my brain are stale and I was not part of any LAT/MOP etc (directly or

Yeah, me neither. MOP on Ultrix is not something I can nail down with enough precision.
However, we can tell for sure that it wasn't before 1984, since LAT actually didn't come around until that year (just checked that one up, so the original question about LAT on VMS 3.5 is a "no" I would say, based on this. My guess is that it might have been introduced in VMS 3.7, but that is purely a guess on my part.)
