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'd always heard that. 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.
Possibly it was built but not shipped, or designed but not built. The document has the look of r a finished product manual, though.
