Apologies if this is in the wrong area.

I had this item dropped on my lap last night and I'd like some info on it. Images:

So it's appears to be a 16-port Harris 9116, and thanks to google and an ad in computerworld ( LINK ) it looks like some sort of multiplexing terminal interface for the IBM 3270. I will fully admit I'm completely outside of my wheelhouse on this hardware. Ultimately I'm tasked with finding a new home for this, but I would like to at least know what it is, what it does, does it work?

I have not applied power to it. It probably boots from a disk, but I don't have that. :P

Side note, I really like saying 'multiplexing'.
