Where is a picture of an HP-41CX? The God calculator of engineers…
Texas Instruments, the only way to go.
Had a TI calculator. All those buttons for the Algorithm function I didn’t understand.
We had a good math teacher. “Can’t use calculators on tests.” Square root? Show your work! I think in four years, there may have been one single question that we were allowed to use a calculator on. Though, a slide rule was allowed.
How ya gonna leave out..

Awesome photos.
You sent me down a rabbit hole.
In the early 90’s I had what I remember to be very similar to the RadioShack ec-4025 in layout and design but I thought I had more lines of LCD and an ability to input as algebraic equations. Went through the old radioshack catalogs. Not sure if it was tandy or Texas instruments, or something else… Totally can’t find what my foggy memory thinks it remembers.
Mostly I used mine to type out 5318008 and giggle like an adolescent. Which I was.
I was of the days of Cobol and Fortran..where a program was a huge stack of paper cards with holes, as long as your arm,waiting to carefully stack them into a chute..hoping, no praying, they were all in the proper order and that you didn’t drop even one..or you were officially …screwed…
My older brother was in high school when I was in junior high. He had a textbook titled “Learn Fortran!” which made absolutely no sense to me. None. Not from page one. I knew then I’d never have anything to do with computer programming. If only it had been written in a clear style like later “Dummies” books. But, alas, ’twas not to be. I turned my attention to Mika’s soft, fuzzy sweaters.
That’s why I switched to a History major.
