Very cool. I remember my slide rule!

What? excuse me, I was just counting on my abacus.

Actually, I had a TI graphing calculator in college, (though not a slide rule), but back then the screen was monochrome LCD, so the logo would have also been black.

Cool!

We did have an abacus, or two, in grade school. NO ONE was allowed to use a calculator in class or for our homework. But as parents, we were required to provide the graphing calculators for our high school kids. They were pretty expensive, too!
Love the puzzle!

That's an excellent Texas! My first computer was a TI 99-4A. I don't remember which model of graphing calculator I later used, but it may very well have been this one.

I still have my TI-81 that I got in like 1993 - used it through high school and college. I wonder if it still works.

Fun puzzle!

Nice puzzle. Great flow it.

I had a Texas Instruments calculator in highschool, early 1980's.

Now I have these three handy:
-TI-34-II
-TI-30XIIS
-Casio fx-260

Thanks, my peeps!
