Cool stuff. I don’t go back that far. Never used a slide rule, and my first calculator was a Ti 35. I always felt inferior to the guys with HPs with reverse Polish notation.
In answer to another student’s question about the final exam my trig teacher said, “it’s more important to remember a spare battery for your calculator than to remember the sine of 30.” I loved that guy.
