Circa late 90's. I was late in the PC world and getting curious about these things. So.. I had a bit of an epiphany and walked in to the library. There in front of me was 6 keyboards and 6 CRT screens. I sat down at one of these things and gave it a good long stare. I didn't know how to make it work, I had no teachers, so I reached over and pushed a key.
Screen started to flicker and woke up to display a "Rules of the library" screen. Now I'm forking excited, so I pushed a few more buttons on the keyboard and the beautiful and most blue screen appears. Now I'm looking over my shoulder, glancing at the librarians at the desk.
Good, they aren't looking, and I crept out of the library like one of the ten most wanted.
It was my first BSOD.
