We had to buy those calculators for highschool and it was a waste of money, felt like somebody must be paying somebody off to have thousands of students buy a device that they will certainly never have to use (and is of little educational value).

I certainly got a lot of educational value out of mine. I managed to program a fully functional Minesweeper game on mine, using the built-in programming tools - no transferring efficient binaries via cable! But yes. 99% of what we did with them in class - when we were even allowed to use them - could have been handled by a little solar-powered calculator with basic arithmetic functions.

30 years ago, we had the option of the TI-82 Or (83?) and the 85. A bunch of the kids with the 85 were playing Tetris and some were writing little programs. I got the cheaper 82/83, and I don't actually remember using it for anything, even once, even though I did the IB track (stats, trig, algebra, calculus, etc).

I was in the not-TI-85 club for a while. I think I had the TI-84? You could still write programs but your variable names could only be one letter. When I upgraded to a TI-85 and got Tetris a friend who had the not-TI-85 asked if his could play Tetris. I checked out the Tetris code and saw there were less than 26 variables, so I figured it could be done. I spent several English class periods porting the TI-85 Tetris code to the not-TI-85 and I got it to work. All the not-TI-85 owners loved me, lol!

My TI-85 story. While I was in prison, around 1996 or 1997, I found out a friend had a TI-85 calculator. I realized it was programmable, so I borrowed it over the weekend and wrote a program to track his stock portfolio. It was the first time I had programmed anything in 2 or 3 years. Then I learned that the US Bureau of Prisons had a rule against any calculator (or device) that was "programmable". So I programmed th…

How long were you locked up in the clink for? Did you get any access to computers there? How did your time there affect you or change how you think? Thanks for sharing

I served 60 months of the 70 month sentence. I had a computer restriction, so I couldn't be around a computer.

Since I wasn't able to use computers or the Internet for that time, I did/read/learned a lot of things I wouldn't have otherwise learned. Learned how to make hooch (prison wine), how the law works and how to maneuver the court system (useful for both civil and criminal cases), got more fluent in French by speaking with some native French speakers from Benin, learned how to work out & lift weights (which I still do), and learned the value of freedom.

I sort of agree. You're paying $100 for completely antiquated hardware where its core feature is "it doesn't do much". Pretty much any professional environment that you will need calculations will have access to a computer that can do these calculations significantly faster and better. I thought my HP was pretty cool in high school, but pretty much the moment I graduated I stopped using it because I figured out how t…

There are many professional examples outside of teaching (construction, lab based science, field work, engineering, healthcare, retail) where a calculator, not necessary a programmable one, is useful because the environment restricts the use of computers due to safety, security or practicalities.

In high school I had the TI-89 Titanium. Like everyone here, I got into programming it using some USB adapter I could attach to my iMac G5 and the TI Connect app[0].

One day, vexed by something, I vented my frustration by composing a profanity-laced rant into the Feedback window of the TI Connect app. (I don't recall the proximate cause, but I remember complaining that the product itself, which is still $110 today, is a total ripoff.)

I was certainly surprised when the (sole?) TI Connect developer responded by e-mail taking umbrage at my complaints.

Perhaps this is a foolish question: how did your friend actually use the tracker? Did he input the prices from the newspapers or TV news?

I'm not sure how much he actually used it after I wrote it for him, to be honest! But we did have access to daily newspapers, and some of us got weekly stock charts called "Daily Charts" by Investor's Business Daily (all paper, of course). Some of us were into trading stocks (this was during the Internet boom 1995-2000). Another weird skill I learned that is still useful to this day.

You're a hero of mine so here is my story. Me in math class in 1996 - I had a TI-82 things are programmable so I have no formal education, my parents are illiterate, and taught myself to program, and I begged them to buy me one. I spent time learning how to code on it, writing from scratch, the game Spyhunter. I couldn't figure out how to draw with lines or pixels so I used ASCII or text. I presented this to my teach…

The fact that you made a game on a device that "wasn't for games" is even cooler.

I feel like there’s a blog post in here somewhere…!

I should do an AMA at some point. There was a pseudo-AMA on reddit a while back: https://www.reddit.com/r/bestof/comments/1z0yx7/first_person...

HP48GX rules, HP Prime is a solid second. SwissMicros DM42N is a solid third.

I don't have a prime, but agreed on 48gx + dm42n without a doubt. I'd add the 50g as another contender, doesn't depend so much on external memory cards (which have the tendency to fail) and is fairly aligned with the 48/49 line.
