Yes, they were hideous hacks of a cheap TV set. The VHF tuner was still in
there, as it was needed to complete the series filament chain. They had 5 tubes in
series, with 26-volt filaments, running off 120 V AC. I'm PRETTY sure the brand was
Zenith, but this is from about a 43-year old memory of pulling the cover off one. All it
had was a keypunch-style keyboard and the TV, all the electronics were in the machine
room.
I thought 2260s had a green CRT.

Sometime
later, maybe around 1971 they got some IBM 2741 terminals which
were Selectric typewriters connected to an interface. Later they got some
IBM 2260's, which were Zenith 9" TV sets and a keyboard connected to an
interface box in the machine room. Very primitive, but very interactive,
great for quick program editing and submission.
Were 2260s really Zenith products
inside? I certainly could believe
it, judging from the tube lineup. Someday I would like to see one up
close and personal.
