Just to give you an idea of how random my brain can be, here is a picture of a set-top cable box identical to the one my city grandparents had in the mid-late 1970s.
Sing with me if you know it, “Eleven! Eleven ALIVE!”
That was the jingle for WPIX out of New York. One of several “superstations” they received through this analog box. Others included WGN-TV out of Chicago and WTBS-TV from Atlanta. My uncle would fall asleep on the floor in the wee hours of the night watching movies on “Home Box”. We now call that HBO.
The stuff I remember. Whew.
Oh, and the television tuner was always tuned to Channel 4, because in Syracuse we already had channel 3 and that would conflict with the signal coming from the cable tuner.
