The first monitor I owned, which was connected to a TV Typewriter, which
was connected to my Altair 8800, was an old Zenith "hot chassis"
portable tube TV. Tapped into the video just downstream from the video IF.
The set didn't have a polarized AC plug (I don't trust those things
anyway), so you had to be a bit careful when applying power (the TVT and
Altair used 3-prong grounded AC plugs). It worked well enough to
provide a clear 64x16 character display.
I believe that Sony used some of their portable transistorized TV sets
as monitors, equipping them with SO239 UHF connectors. I recall having
one of those as well.

Now that I'm thinking about it, there were also instructions for hacking the
composite signal straight into the TV, bypassing the tuner... but Mom and
Dad probably wouldn't go for that (mine didn't).
I paid a local electronics store to add an RCA composite input to our old black &
white TV, bypassing the tuner. It think it cost $50 at the time (early 80s)
