I assume you had to pay for the cost of printing. They could be freely
reproduced, though, it says so explicitly.

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.

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.
