Those who have used various classic HP calculators in the past may be interested in this: https://www.swissmicros.com/products These are clones of various older calculators.

I bought a DM42n last year. I didn't need it. I don't use it so often that I can justify its purchase. Still, wow, I do so enjoy working with it. It's one of those tools that just feels good to use.

Earlier quoted context omitted.

I used mine constantly in highschool (10 years ago).

I used mine in highschool (20 years ago) and still use one today.

Same except mine was over 30 years ago (an OG TI-85). Still on my desk, still use it almost every day for something or other.

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...…

International Baccalaureate math has some stats questions that require a calculator that can do stats questions. Not really possible by hand in exam conditions!

The basic $12 Casio scientific has stats like mean, standard deviation, regression... Stats is a huge field, we're talking highschool level. I think it probably covers it

Generating a QR code to see the graph online is kind of cool, but also kinda dumb too.

I mean, these days kids have smartphones, what's the point of a graphing calculator?

From here: https://www.cemetech.net/news/2026/4/1062/_/ti-84-evo-calcul...

> 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.

It has Python? That's pretty cool.

It doesn’t have a qwerty keyboard. That would be such a pain to type on.

For some reason qwerty keyboard calculators are banned in tests.

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.

Honest question: Why do we need physical graphing calculators anymore? Can't this just be a phone app? That screen resolution for one is horrible for 2026.

i moved my ti-89 to be a phone app, but it was much much slower to type on the soft keyboard than it is to press the actual buttons.

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.

Biggest ripoff in academics. There should be a cheap open source calculators for schools and exams. It’s ridiculous that TI is still charging this.

The biggest ripoffs were the textbooks. Especially the textbooks written by the teachers, themselves, who forced you to buy them.
