A regular VT-100 puts out composite/RS-170 video on a

(Classic problem from a few decades ago: people plugging the school's
thinnet ethernet onto the VT-100 video out connector!)
I don't see any BNC's on the back of Francesca's Franken-VT-100. But
I'd be pretty sure the Ball Brothers unit just takes the composite video
in.
Didn't some early regular VT-100's use Ball Brothers screens and flybacks
too? I remember a couple variations of the CRT/flyback boards some more
reliable than the others. Somewhere I've got pictures of my garage
completely filled with VT-100's!
Hi actually it does have those BNC's and yes when I was working at JPL back in
the old days I had to explain to a person in charge of one of the computing
department's that in fact they could not create a network series of VT-100's
using the then new Thin Net network being installed lab wide. :-)
The problem is the small size of the tube actually. Now the part that is broke
is the neck. I am thinking maybe I can find a smaller CRT from a scope or so
to replace it. But that would be after I tear this thing apart since the label
for the crt itself is of course upside down and blocked by the flyback/scan
board. I do see a E C as a possible company name on it.
