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).

It's wild how much curricula within high schools must differ, because my school went out of its way to teach and encourage/require its use on nearly every quiz and exam. We joked sometimes class felt more like calculator class than math class. This was Texas, too, which I hardly consider a pioneer in education. Maybe TI pride?

Now that I think about it, this could have been a strategy my high school drilled into us as a way to increase SAT scores, since TI-84s were allowed to be used there.

I suppose it depends if you took advanced math classes or not.

My high school required one for a math curriculum that was specifically designed with the idea that students would not need advanced math classes. It kids up for failure if they were hoping to move toward higher level math in college, as the fundamentals were never adequately taught. But at least they sold thousands of calculators to kids who would never use them again. They actually started us on them in 7th or 8th…

$100 for something you'll use all through middle and high school and into college isn't a bad deal.

About 25 years ago my parents got me a Ti84 as a surprise for Christmas and they hid it in the attic so I couldn't find it in the meantime. A few months went by and a couple days before Christmas, when it was time to wrap the presents they couldn't find it anymore. My dad went out and got a Casio something as a late minute replacement, and that was the calculator I used in high school and I never knew about this stor…

Must have been closer to 20 years, 84(+) didn't come out until 2004. Gonna be pedantic/crotchety about this because I got into advanced math classes but it was my brother who got the 84+ (I had to settle for a 83+). Guess who's the engineer now, and who's the NEET? Your kids pay attention to what (who) you value, folks.

I don't remember there being much of a difference between the 83 and 84. Did you care about the amount of memory or the clock speed of the processor? Or was it more of a status thing.

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.

Programming mine in high school is how I ended up coding for the first time and led to my current career. Honestly a pretty good investment (from my parents) I'd say.

This new one has python, imagine

Yeah I guess I should correct and say that I do use an HP 50G emulator on my iPhone cuz I like RPN. But even still, the iPhone can do many things and is many times more capable, and you can buy a used iPhone 12 that works fine for about the same price as one of these calculators.

HP 48G(X) is the OG and what I took SAT-I and AP Calculus BC exams with. The iOS/iPadOS emu app is called i48.

Android app is called droid48

Hahaha! This is great. Somewhat related. My mom once yelled at me for losing a necklace she really liked. Then we were moving her stuff out of her house and found the necklace behind a wardrobe, wedged between it and the wall. It had been there for like 40 years, layered in dust.

On 9 July 1537, Martin Luther wrote in a letter to Wolfgang Capito about a lost golden ring: "Pro annulo aureo gratias tibi agit mea Catharina, quam vix unquam magis indignatam vidi, quam ubi sensit, cum vel furto sublatum, vel sua negligentia (quod nec mihi verisimile est, licet usque ingerenti) amissum, quod persuaseram ei, hoc donum esse felix omen et augurium ei missum, tanquam nunc certum esset, vestram Ecclesia…

If my grandmother were to find out that housekeepers occasionally do actually take things, it would set us back decades.

Back in the mid-90's we had a TI version of sneakernet where you would copy programs from one student on to your TI-85 via a link cable; this is how I got Tetris back in the day. I assume OP did the same.

Was it that only the 85 could connect to a com port, but then you could connect the 85 to the 82/83? I seem to remember pleading with the one kid with an 85 (who didn't even care about games).

The 82 also had a com port

I don't remember if you could connect an 82 to an 85, but I do remember you could connect it to a PC as well over serial

The Python inclusion is fascinating to me. I, like many other kids in the US, did a lot of calculator programming with the TI-84 back in school. It definitely taught me the basics in a way that made my CS classes much easier. I'm jealous of the kids who now get to make that journey with Python instead of TI-Basic.
