Thanks for taking the time to look into this! Comments interspersed below.

Yes. VMS runs fine on SIMH with this network setup, both DEcnet and TCP-IP.

Up to here, all good.

Interesting, I'll look into that. But - there's a cable allright.

Yup. Should be, is not. I've downgraded to a very simple 11/73, rq, tq,
xq, dz setup and verified the QBUS config. In SIMH, everything looks
allright. In RSTS INIT, no such luck. The only time I succeeded
generating a QNA device into SIMH RSTS DECnet, was with a UNIBUS 11/94.
But that did not work (and it should not, really).
I'll keep trying...
