-very very dim memory here-
I had some exposure to these at the UW ACC (University of Washington
Academic Computing Center) years ago.
ISTR that the video is a 75 ohm input, you might be able to feed composite
video in to it, the unit was cabled up to a unit with 8" drives and the guts
of the word processor in it. Also those things had a bad habit of eating
disks, the drive kept spinning with the heads loaded at all times, if you
powered it off without going through the usual shut down procedure you more
often than not corrupted the data on whatever sector the head was over when
you power-cycled it.
Please be kind to me, this was probably 20-30 years ago now that I was
around any of these.

What I find especially strange about this one is that it's called a
"Word Processor," suggesting it is a complete system, yet it has ports
for neither storage nor a printer. Could it be a terminal to a
networked (WangNet) system? Still, the only ports on the back are
Video and Keyboard - both of which it has built-in. They could be aux
video in or out, or an attachment for an add-on keyboard?
I'll hazard a guess it is a very-dumb terminal: the connectors could be
video-in for the monitor and keyboard-out, the smarts all being
elsewhere. Could open it up and see how much (if any) logic is in
there.
The 5506 is practically mint. The guy I got it
from said he had the
original box but it was in such bad shape he tossed it :( There is
still shipping plastic on the space bar and the screen. Turning it
on shows a blank greenscreen - turning up the brightness shows
diagonal lines, so there may be a display problem.
Sounds like the retrace becoming visible, turning up the brightness on
a raster scan often shows this, notably the horizontal scan lines
during the vertical retrace interval show up as angled lines.
