I think they were in some 70's or very early 80's DECDirect catalogs. 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.
