The handheld electronic calculator turns 40 this week! Who'd a thunk it?
I can remember lusting after a HP scientific in tech school. Anything to replace those laborious calculations on paper. (I was taking toolmaking and machine design, so no slide rules allowed. We had to be exact for several places past the decimal point.) And when I finally got one, I was the envy of the shop. Everyone came by to use it, until they got their own. And then programmables really made us hot stuff!
Anyway; they're all here, from the desktop model the CPA for your grandparents used to the zoomiest scientific model.
