The display was most likely a Tektronix 611. DEC used them with their point plot display
systems like the VC8E.
I am pretty sure that the display was a 611 in its vertical configuration:

The display was a fully enclosed standalone unit, not a bare chassis. It sat on top of the
bottom chassis of the terminal and then had another cover fitted over it.
It had screen burn which indicated its use as part of a text terminal, but I don't
know if the character generation was originally performed in the bottom chassis or by
external equipment. The small DEC wire wrap backplane in the bottom chassis didn't
seem big enough to implement all of that with flip chips. Maybe the backplane was just
used for keyboard interface, and character generation was done by equipment external to
the terminal?
