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.
