>They were also VERY suspicious any time you had your graphing calculator out outside math class, and some of the ruder study hall attendants would clear your calculators memory of games.

That would have been a huge bummer becuase I wasn't playing games on mine, I was writing programs. It was actually the start of my professional programming career technically. I sold a copy of the program I wrote via link cable to a fellow student for $1... 8 years before apple was selling $1 mobile apps ;)
