At this point, the V3.5 node 31.42 (XXXV) continues to happily speak Phase-IV on UNA-0 and Phase-II on DMC-0. I have added guest accounts on both 31.42 (XXXV) and 43 (XX) with password welcome123. So, to log into VAX/VMS 2.0 from any HECnet node that supports RTERM, 31.42 (XXXV) can be used as a jumpbox. Per Paul, if DECnet/VAX v3.0 running on VMSv3.5 implemented intercept, it would have been a great router.

I also wonder how V3.5 and V2.0 seem to be fine with current clock times.

Anyway, from an ovms7.3 node, for example, here is logging into VAX/VMS v2.0 with DECnet/VAX v1.5.

$ set host/appl=rterm 31.42

Welcome to XXXV (31.42), a DEC VAX-11/780 running VAX/VMS 3.5

You can login over DECnet using:
  $ MCR NCP SET NODE XXXV ADDR 31.42
  $ SET HOST/APPLICATION_PROTOCOL=RTERM XXXV

If pydecnet implements PMR (Poor Man’s Routing) and allows connection between any 2 DECnet phases you might be able to make something work.  It would look something like:

set host <PyDECnet-node>::<destination-node>

ah yes ... it was worth a try. thanks.

$ set host pipy::xx

Should later VMS be able to talk to it ? It doesn't seem to work for me (VMS 5.4):

I haven't been able to talk to it from VMS later than 3.5 either. CTERM and RTERM don't seem to find what they look for.

PRRSI$ set host 31787
%SYSTEM-F-CONNECFAIL, connect to network object timed-out or failed

If I try from VMS 7.3

KRAKAR$ set host /app=rterm 31787
%SYSTEM-F-LINKABORT, network partner aborted logical link
KRAKAR$ set host /app=cterm 31787
%SYSTEM-F-NOSUCHOBJ, network object is unknown at remote node

tcpdump attached (31.12=RSX, 31.43=VMS2.0, 31.32=pydecnet); here's what
RSX says - it tries "RMT" and fails. TOPS-10 uses "NRT" and succeeds.
