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.
