Have you used your calculator for something that was not really math related?

[Dave Britten]

I have a 48G with a slightly messed up screen (some annunciators are stuck on) that I got for $5, and I've used it as my alarm clock for quite a few years. I have a couple simple programs on there to set an alarm for work the following morning with just two keystrokes, or I can put a time on the stack and set an alarm for the next occurrence of that time. I have to correct for clock drift every few months, but it works great otherwise.
