[HECnet] DECnet et al

[hvlems at zonnet.nl]

Decnet 3 is compatible with phase 4. DEC was great with upward compatibility. 

I thought ethernet (10 Mb/s, thickwire) ws from 1977, VMS is about the same age.

DECnet phase 4 is about as old as ethernet and VMS.   Ethernet was the main driving force for phase 4 owing to the large number of adjacent nodes and the sheer number.

Not really. Phase IV is about as old as ethernet, yes. VMS is older...

Phase 3 does not have areas and only recognizes 255 hosts max. It did have circuit routing (of course)

Yes. About the same thing as L1 routing. I think it might even be 
partially compatible, within the restrictions on the number of nodes...

  FWIW, that's a "switch" at least in the common usage of the word over
here.

Hello!
I agree! Now first things first. When did DECNET first appear? And
more importantly, based on what systems and using what means to
connect each system.
