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 meant that RSX-11D was the only supported PDP-11 OS. The RTS/8 DECNET/8
SPD is up on bitsavers with a date of May 1977 so it was already a late addition to
the Phase I development - I had joined the networking group in the Mill in Feb 1977
to work on Phase II. The SPDs for those Phase II products were dated Jun 1978
which seems about right.
