NCP is that network control program? "Network control protocol" and "link
control protocol" I am finding is part of PPP. So RFC 801's reference to NCP;
is that "network control program". I appreciate being corrected. Henry's BBN
question is very interesting.

Well RFC 791 doesn't mention any "link control protocol". Maybe it never
existed. Well modern man's highest acheivement launched in 1983 I see then. I
just can't get over the way IP packets split, find the shortest routes and
recombine at the destination :) amazing. PDPs are certainly mentioned
An offhand comment on another list led me to find out that a DPS-8/M
emulator of sufficient completeness to be running Multics (with
month-plus uptimes) has been created based on SIMH code:

Have the creators of this simulator been approached about possibly

On the history of networks, there was also a network called BITNET which
was mainly used
by educational institutions using mainframes. Started around 1981, it was
originally based on
the bisync protocol and was a store-and-forward system. At it peak it had
about 500 organizations
and about 3000 nod

I assume you are referring to the DG MV (32-bit) systems - there were
several DG E'net controllers for the MVs. What is the board's 005-

Network was only implemented on systems that were in active development
past the mid 1970s, when commercial networking stacks like TCP/IP,
DECnet, SNA, BNA, etc emerged. There's an
