If they were TNC (threaded not bayonet) I'd suspect it to be a CI
interface card (from an HSC50 or the like).
It doesn't look like a DEC board (unless the digital logo is on the
other side). The cable attachment for those coax cables doesn't have
a DEC look to it, either. And the picture of the back has a mil-spec
look to it. I wonder if this is a military databus interface.
It's hard to tell from the back panel photos. Are those connectors
actually BNC, or are they like BNC but a bit smaller? Do they have
three or four prongs instead of the conventional 2 bayonet prongs? If
so, they'd be TPS connectors, which fits the databus hypothesis.
