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