In the late nineties I used to work at a Quasar centre (a type of laser tag), and the control system was a two-up DOS display built out of ASCII characters. Even then, we joked about how old the computer was (a 386 IIRC, a long time back now). It still strikes me that while the hardware in the packs failed pretty often, I can't recall a single crash in that software the entire time I worked with it. I suspect in retrospect it was statically linked with few to no dependencies, which probably helped a lot. EDIT: I'm even older than I realized. Shit.
