The first calculator I ever saw was in a psychology class around 1971. The professor who had just arrived from England said he was surprised to find the department had one.

He passed it around for all of us to see. I have no idea what the functions were but he said it was very expensive.

I think it was around the size of a hymnal.

In 1974 I bought a basic scientific calculator from Sears for $69. It was reduced. It still works and has beautiful green numbers which are easy on the eye.

Maybe in ‘65 or ‘66 I took psychological statistics. We had a room full of Marchant calculators that could with a great deal of effort (and holding one’s mouth just right) calculate square roots. There were at least 100 keys on the machine and it was incredibly easy to make a mistake. It was electric, but really just mechanical.
