There is a genuine-looking MOP functional specification online, e.g.
at
decnet.ipv7.net/docs/dundas/aa-k178a-tk.pdf (this one is apparently
OCR'd).

Isn't it nice how it's easier for me at home to find (and read) thirty
year old obsolete documents (at home) that I have no need for, than it
is for me (at work) to find and read regulatorily-required PC
documents from only ten (or even two) years ago. Progress is a
marvellous thing. One day there'll be some in the IT departments of
the world.
