Its a terminal concentrator. I have a load of those 8 and 16 line cards.
They would have fanned out to via splitter cables to back /front panels
with 9/25 way D connectors.
They look in a bit of a sorry state. I would not apply power or plug
into any other chassis.

These are the cards in the DecServer 550. Looks to be an expansion
