Mostly a curiosity rather than practical, but I got to thinking about how some of the TV boxes that run Android (rather than the proper AndroidTV boxes) have the output, and since I've never heard of the proper boxes having one the ability to hook up to old school TVs is one of the few advantages the lesser boxes might have, though that advantage will get smaller over time as the holdouts get replaced
If you have a TV without HDMI then I'd say it's time to get a new TV.
