  • I'm surprised to see "Approved for Exams" featured so prominently, as handheld calculators for lots of standardized exams are being phased out.

    All of the exams listed are either already offered in a computerized format or in a transition phase, with the PSAT, SAT, APs, and ACT all already offering Desmos in their testing apps.

    I love handheld calculators, but, especially in a time-sensitive environment, it's hard to beat a large screen and full keyboard.

  • Ti really needs to stop with the artificial product differentiation. There's no reason 15 years after the Nspire CX CAS came out that everyone of their calculators can't do CAS.
  • Summary of the comments in here:

    * I used the programming functionality of the calculator to get around the rules

    * I didn't care much for the math, but my TI calculator was my first programming experience and it's what got me to love programming

    My experience is similar. We were allowed to use our TI-85s in class, but we had to go up to the teacher before the test and show him that we were running a factory reset, to prove we had nothing programmed in it to cheat.

    My buddy and I had made a two player blackjack game and didn't want to have to retype it after every test. So instead we made a program that mimicked the factory reset process. You would run the program before walking up tot he front.

    The only indication something was different was the three little dots in the corner indicating a programming was running, but we just covered that with our thumbs.

    Ironically we never used it to cheat, only to not erase our game that we programmed!

  • Show me a highschool math problem you can't do on a $12 Casio scientific like the classic FX-300MS https://www.usaofficemachines.com/csofx300ms-fx-300ms-scient...

    There's even knockoffs of it for $1: https://www.aliexpress.us/item/3256809744184708.html

    I picked one up when the 99 cent store was shutting down. It works fine.

    Look what you can get for $20: https://www.casio.com/intl/scientific-calculators/product.FX...

    TI is like the Intuit of the education world. I want to love them but this is ridiculous - a N4120 celeron laptop is the same price as this new calculator - it might be a garbage laptop but it's doing a heck of a lot more for your $160 than this calculator is.

  • 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).

    > 3x Processing Power - Matching one of the speculated options, the calculator appears to use an ARM Cortex CPU, finally retiring the z80 and ez80 family of CPUs that were used in three decades of TI-83 and TI-84 Plus graphing calculators. It's running at 156MHz, compared to the 48MHz of the older calculators. It appears likely that in an unexpected break from over 30 years of TI's operating system codebase, the OS has been re-implemented with new features natively on the ARM CPU rather than using an ez80 emulator to run an updated form of the TI-84 Plus CE operating system.

    It looks like TI is finally moving away from the Z80. This must have been a pretty big engineering effort on TI's part. Like the article says, up to this point all of TI's low-end graphing calculators have been Z80 based and use the same system software that has a lineage dating back to the early 1990s. They were previously so wedded to the Z80 that when they introduced Python programming to their calculators, they did so by adding an ARM microcontroller that runs MicroPython, while the main eZ80 CPU acts as a serial terminal.

  • 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 story. Then last year I found a Ti84 in my parents attic...
  • 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 the TI-85 so its startup screen read, "TI-85 NON-PROGRAMMABLE CALCULATOR". Problem solved.
