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.

But recently I found Phase I documents, which include protocol specifications of a sort, sufficient to tell that it wouldn't be compatible with Phase II and couldn't readily be made to be. (In particular, NSP works rather differently.) And that document was for a PDP-8 OS.

The document I referred to is a full manual "RTS/8 DECNET/8 User's Guide, Order No. AA-5184A-TA". A note at the start says "converted from scanned text 1-Jun-1996" and just below that "First printing, February 1977". Chapter 6 is a fairly detained description of protocol message formats, which look vaguely like NSP as we know it but only vaguely.
I don’t know if it ever shipped. An SPD would imply that it got pretty far along in the
