I recall when I first learned of these as a kid. When I was a youngin' we traveled with my dad out of state and stayed in a hotel so he could get some extra training for his job. Because we were going to be there all week my dad hooked up my intellivision and/or atari to the hotel tv (obviously using this connector or one very similar). Not long after there were four cop cars in the parking lot, lights being shined in the window and we were being yelled at. I (a stupid little shit, age 4) just kept playing my game and ignored the chaos. Turns out Dad had somehow disabled some kind of anti theft on the TV when he hooked up the system. Rather than phone down and ask the hotel called out every barney fife in a 20 mile area. Eventually my poor father (several sheets to the wind at this point) was able to convince the cops that for at least the week I was stuck there that was the safest television in the county. At first the cop was going to make him take off the connector to plug back in the anti theft alarm, but I lost my shit (did I mention I was a stupid kid?) and they relented. I'm sure they felt sympathetic for my family if they'd been cooped up with me in that tiny room for a week with zero entertainment. That was my first real interaction with one of these adapters (as it usually just stayed hooked up to our TV and I never thought about it)
