No. A Toad cannot talk DECnet at all, as far as I am aware. It also do
not have Prime support, so you would not be able to talk DECnet to it
even if you did implement this. Basically, for the time being, Toads are
out of DECnet, in all aspects. They are IP only.

Right. And since the only Prime implementation that I am aware of would be the PyDECnet
one, it means you can talk DECnet directly between those, but not to anything else.
However, you can also achieve this by just having GRE, Multinet, or whatever in between
those two nodes, and just use IP.
Yes, IP would work for nodes having Multinet support. Can a Toad do that? On Mar

The problem with Phase IV Prime is that it will not be compatible with any other Phase IV
node, so it would be of very limited value.

is any other hardware with that limitation it would work there as well. The changes are
pretty modest, especially for end nodes.
True. But you will only be able to talk to other Phase IV prime nodes. And I don't
think I've ever seen any, so that would boil down to just be able to talk DECnet to
other PyDECnet nodes. Not sure how much value that would have...
Phase IV Prime can
only talk to prime neighbors, but via a prime router it can talk to anything else just
like regular Phase IV. So it should be useful; the only limitation is that you'd need
to have a Phase IV prime router adjacency. But I don't understand your other point. If I
have a prime endnode, adjacent to a prime ("bilingual") router, it can talk to
MIM, or anyone else on the HECnet.
Correct. But my point is still that there is noone talking Prime. Your
implementation would be the only one, so you could only use it to talk
to other PyDECnet nodes. And those PyDECnet nodes can already talk to
each other, even over WiFi. So I see very limited value in implementing
Prime.
There is of course also the point of "I can do it
so why not?"
Always a valid point. :-)
