History of Technology
Early computers and PCs, here. This seems like the AppleIIe (I think it was) on which I learned to write tiny little programs in BASIC, back in high schools in the 80s.
I'm sure we didn't believe the teacher, who surely told us that one day we would all use computers, every day. But then again, I certainly didn't believe I would need to know how to solve problems like what % of increase is a $25 a week raise for a camper counselor. . . .
