I assume you had to pay for the cost of printing. They could be freely reproduced,
though, it says so explicitly.
There was at least one implementation for Linux
and (I think ...) another for Solaris. cisco also supported DECnet in some of
their switches.
Yes, and for that matter, there was a commercial non-DEC DECnet, by Stuart Wecker I think
-- he was involved with DDCMP way back when.
That was Technology Concepts Inc, Sudbury MA. Sometime around 1984 I almost left
DEC to join TCI but then had a change of heart. Sun?s DECnet implementation was
either done by TCI or based on their code.

I suppose so. Rumor had it that Phase I only existed on RSX, but it appears that there
was a PDP-8 implementation as well. Phase II was implemented on lots of DEC systems, from
TOPS-10 to RT-11 to RSTS/E. My initial involvement with DECnet was as the DECnet/E kernel
guy, upgrading DECnet/E from Phase II to Phase III.
I worked at a customer site in Sweden which consisted of a pair of 11/40?s
running
RSX-11D and DECnet Phase I. I?m pretty sure that Phase I only ran on 11D in the RSX
family.
