I'm in the age group that spans the end of the slide rule with the beginnings of calculators and personal computers. As a high school senior, trigonometry was the highest math class and we learned to use the slide rule in it. I still have the one my dad bought me for my birthday that year. In college freshman calculus, I remember one guy brought his HP-35 to class and everyone else being awed and amazed by it, including the professor. It was too expensive for me but I was able to buy a TI-50 the next year. Functional but it wasn't an HP.
