That takes me back a while... 6 channel paper tape equipment, for communicating with typesetting machinery of that era.

Which reminds me:

I don't know anything about ANF-10.  But while routing appeared in DECnet with phase 3, that was not the first time DEC did routing.  Earlier (late 1977, I think -- certainly by summer 1978), Typeset-11 did link state routing.  It had a primitive kind of cluster that operated by passing work around as files, via a proprietary protocol over DMC-11 links, with link state routing.  It was pretty transparent: terminals were connected to any of the nodes, and could edit work and pass it around (to other people or to processing components such as typesetting back ends) independent of the location of those other resources.
