I still remember messing with the vertical hold control of my old assed tv trying to descramble the Spice channel (don't recall the actual channel # but I am pretty sure it was in the high 50's) when parents were at work during summers. It was a "cable ready" digital channel display (showed on an LED display instead of on the screen) television that only went up to channel 99 or so, complete with a particleboard cabinet with woodgrain finish. I reckon it was from the mid-late 80's since I recall it from early childhood. Was given to me for video games once we got a newer one for the livingroom. Sadly I don't recall the actual make/model and cannot find any similar online.
We actually had HBO for about a year until mom realized there was porn on there late at night.
