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.
I worked at a customer site in Sweden which consisted of a pair of 11/40?s
running
RSX-11D and DECnet Phase I. I?m pretty sure that Phase I only ran on 11D in the RSX
family.
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.
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.
