My high school video editing class used Amigas running Video Toaster. Because AmigaOS was designed in more innocent times, other programs could scribble on Video Toaster's framebuffer and, after discovering that, all of our projects started including cheesy demoscene effects. Much to the teacher's frustration, we learned much more about display hacks than video production.
I beta-test Pro Tools, the preeminent audio editor/mixing application. When you break it in a truly deep way, it throws up an error that says "MagicID Does Not Match" followed by a 5-digit string. You know you're breakin' shit when it tells you you didn't say the magic word.But ultimately, the technology was fallible, and it, too, is something cable fans remember the Prevue Guide for. The Amiga was known for its unusual error messages, particularly "Guru Meditation," which was its equivalent of the Blue Screen of Death.
There's a great documentary about the founder of Newtek expending a huge amount of time and money to test a pet theory. https://en.wikipedia.org/wiki/Tim%27s_Vermeer Not on topic but I really like that movie
