As a kid i remember being fascinated by technical difficulties screens, EAS tests, etc. Generally anything that unwittingly revealed the technical aspects of running a broadcast station. This was before we really knew how to use the internet even, so for many years, I'd wonder what a screen saying "No Access Card" or "Coriogen Eclipse" meant. When we learned about Google, it was suddenly a very educational experience to google these things and learn what was going on behind the scenes. I'm a software engineer today, but surely the nearest parallel universe version of me grew up to be a broadcast engineer.
On Toronto's public transportation, TTC, occasionally the upcoming bus stop ticker would flash diagnostic information(?) and "64K RAM" instead of the upcoming stop name. Doesn't seem like there's a wiki page about these faults yet.
