Hi Tim,

Good Eye,

I had to look inside but I found a sticker for a Ball Brothers Model TV-50 :-)

The main logic card is in fact a generic Digital VT-100 logic board. Although 
I would guess the proms are different.

Unfortunately the CRT neck is broke :-( 

Was not packed very well at all by the shipper

I guess I can search around for a CRT somewheres unless anyone has a idea. ??

So I guess between this and that SB-11 (And a TU-58 I don't have) we have the 
makings of something interesting for sure. This system did at one time reside 
in the custody of a Harvard professor according to whom I got it from. Wish I 
knew a little more about what it was used for back in the day.

...
  Ah, those are very interesting pictures. I'm
pretty sure the CRT and cage
 and PCB are Ball Brothers units, can you look for stickers with their name?
 Ball Brothers made CRT+deflection circuitry+ flyback modules used in
 other equipment, and at one point I even had
 an IMSAI cabinet with backplane and a Ball Brothers CRT incorporated into
 the front panel.
