Man, I'm a bit miffed. My batteries ran out on my calculator a few weeks ago, and I just now replaced them. It's a TI-85, IMHO the best calculator ever made and the sole reason I got through college. I had a ton of programs I wrote for it stored in its memory. It has a seperate battery to save the memory, but alas, when I put in new batteries, the memory cleared, it hadn't saved the old programs. I've always been meaning to try and transfer them to my computer someday, but I never owned a PC and didn't have the right cable. Oh well, I suppose I'll just have to remember them fondly.

What's more amazing though is that they were the original batteries I put in when I got it, in 1994. Guess I should be able to get another 10 years out of this set.
