This is the first calculator I remember having in our house. I'm pretty sure you had to plug it in. I remember tapping away at the keys thinking I was some kind of astronaut.

We had one of those too. They were too cool!
I still have a scientific TI calculator that I use occasionally. Have you seen the current crop? While they may be replaced with apps, the new dedicated calcs are incredible.
Back OT, anyone remember getting paddled? And the shop teachers having paddles that looked like a thick butcher block with holes drilled in it? The PE coach using his whistle leash? I guess that may be just me.
