Had to think about what the "oldest" working piece of technology I own is. I think it is a Casio fx-11 "Scientific" calculator from 1974.

This belonged to my dad. I last "fired it up" sometime last year. It takes 4 AA type batteries. Power switch is "iffy" but if you wiggle it enough it will turn on.

One of the most interesting features is the green flourescent tube display and the "little" zeroes. So "ninety" looks like "9o."
