I'm now imagining this.He's holding it like it was a smartphone, too.


Wow. Calculators already in the 70s! Maybe you have a fun memory of using it during the first days, Edd?

When I was a Freshmen in college (1973-1974), there was an EE (electrical engineering) major that lived several doors down the hall in the dorm I was in, who had been on HP's want list for one of their new, programmable calculators for 6 months. I seem to recall that he had made a downpayment of some $ 400.00 to get on the list and owed an additional $ 300 upon delivery. Due to his major, I'm guessing that he made VERY good use of that calculator.The calculator craze quickly escalated as expensive brands like Bowmar and Hewlett-Packard were joined by less expensive brands like Texas Instruments. The arrival of pocket calculators became a "guy-thing" with price becoming a status-thing. Yes, these tools were great for math and science work but because calculators were always in view, even when not in use, the status of these expensive toys took a toll on poor kids in my school.
The big event hit by Christmas 1976, that was the first time I saw a calculator by Casio, the brand that set the calculator market on fire!
If you couldnt afford a calculator and couldnt even afford a slide rule, you used a log book.
These books made it not too hard to do complex calculation using simple addition. It was worth learning how to because only log books were allowed in an examination, anything more modern was considered cheating.

In a university education course in 1989 we had to learn to use these because there were still school out there that relied on them.
I remember those as well, although they were much rarer. Maybe even one per school rare.It's surprising how many places you can still find them in use, though their companion type that you can put anything under and project it are more common.
Professors still used these at my university in the early 2000sView attachment 3188029

I finally threw out my overhead slides in 2013. Up until then, I still occasionally had classrooms without any technology more advanced than an overhead projector.Professors still used these at my university in the early 2000s
