The only thing on my Christmas list when I was 14
My 30+ year-old Casio fx-7700G is the oldest calculator in my collection. It's a little worn, but still works and gets used! It's been a wonderful companion over the years.

This might be the best looking graphing calculator I've seen.
It is a beauty, but it's sure seen better days. It kept displaying
Low Voltage, even with fresh batteries. I cracked the case in a few places taking it apart to fix it. I have no idea what I did, other than touch a multimeter to a few spots on the board, but it works fine now. Dumb luck, I guess.
