Some of my classrooms had large slide rules at the front of the class, about six feet long and one a bearing so you could rotate it to use the back side. I never saw it used because we all had calculators.
My brother brought me a tiny Casio from in the late 70's, it was less than 4" tall. I used it for six years at University. It had every function I had ever seen, RP notation, stats, and a clock/timer. It was tiny and a lot of my classmates laughed at it. But it was actually very good.
