To be fair, a large percentage of the population will never use a graphing calculator after they graduate high school.

I don't think they had graphing calculators when I was in college, and I minored in Math! And I can attest to the fact that I've never needed one. It would have come in handy in high school and college, but not so much afterwards.

Recently, I came across one of my notebooks from college from one of the three semesters of Calculus that I had to take. It amazes me that I understood that stuff back then, because I certainly don't remember any of it.

Some of us had to go thru college w/ slide rules... calculators w/ more than basic functions didn't spring up until after college. When I was in real estate and mortgages, calculators were ever-present. I was surprised when Baby Buzz used his Ti grapher after college.

And Todd, I'm not sure how much legwork you're willing to do, but searching large metro area CL's does show a few $20 - $30 units available. Again, may/probably be lost/stolen recoveries, and you'd have to secure shipping arrangements, but at least budget friendly.
Good luck.

Folks,

Thanks for the feedback.

This is another example of what a great community this is. A simple request for a bit of second-hand tech turns into a fairly interesting discussion expressing various viewpoints about how technology changes over time.

Never even thought that pursuing a used calculator had a risk of ending up with stolen goods. Thanks for the heads up.

I’ve found (and purchased) something I’ve found on ebay. Hope it’s legit.

thanks again, Todd’s polar keyboard

Last month my son requested we send him his TI-84. He is 27 and last used it in college for his math minor. He needs it now because he is using it during his qualifying exams to become a math teacher - he did not major or minor in education so it is a process.

[N-OS X-tasy!]

I purchased a TI-85 in 1990 as I was starting my engineering studies. Really wanted whatever HP model was new at that time, but didn't have the ching to spend on it. The TI-85 had more than enough capability to get me through my mechanical engineering studies, though, so all was good...

...until I discovered Excel a couple of months later. The TI-85 went into a drawer, taken out only when I needed to use it to take an exam. It's still in the drawer to this day -- poor little guy never got to live up to his full potential.
