As someone who built a custom serial cable (not my idea, greetz to the original designer) to load assembly programs on TI-85s for all my friends, the “approved for exams” shit is so funny

the best calculator is of course a RPN calculator, preferably a HP 48GX, but HP Prime also suffices. Swissmicros DM42N is a good second :-)

I learned to program on a TI-83 and later bought a TI-84+ with the cable that allowed me to transfer my apps and games between my device and other students devices. I have fond memories of hand typing into a TI-83 BASIC for hours using code I found online at the local library - games like Drug Wars and other similar choose this or that console based games. I would later get a USB cable that allowed me to download apps and games onto my device. Good times. Decades later and I'm still programming.

And those goddamn displays still have the pixel density of a Tamagotchi.

$160 at Amazon: https://www.amazon.com/Texas-Instruments-TI84-TI-Calculator/...

Not as bad as I would've expected. Also, apparently it includes a very simple Python environment? https://education.ti.com/en/product-resources/eguides/eguide...

For a $10 BoM and maybe a year of R&D I would say that $160 is bad.

Their engineers are still trying to figure out how to make backlit keys. Just give them another two decades, I'm sure they'll crack it.

The $0.03 LED, $0.04 diffuser panel and the extra 3 cents for manufacturing keys with transparency will eat into their 93% profit margin. Can't have that. The children will just have to use a desk light.

A TI-83 was about $100 in the year 2000, and it doesn't look like it's that much cheaper today. I would've expected Texas Instruments to try gouging their very captive market.

But you can't divorce that from computing technology in general. A TI-83 used a z80 in 2000 and was priced at 1990's z80 rates, it was already gouging even back then! Now 26 years later the TI-84 uses an ez80 (or something something similar), which was introduced in 2001.

TI has always gouged their captive market. It is just increasingly ridiculous when those students also have smartphones.

FWIW I think these graphing calculators are quite good for 2026 students! It is nice to have a computer which is actually comprehensible. They just need to be more like $50. $160 is just evil.

This has a 156Mhz processor.

My lightbulb has more calculating power than that.

Shrug. The SAT and ACT don't let you use an iPhone on their exams. $160 is what the market will bear. I'm not saying it's right or wrong, it just is, and perhaps there's a market for a much cheaper competitor to beat TI here.

Is it a free market? Can students choose any calculator they want as long as it’s certified for their tests or is it mandated by the school?

You can use any calculator that meets the restrictions for things like the SAT.

However.

The entire year, your textbooks, your teacher, your in-class practice, was walking you through the specific commands you need to select to actually do the things, like graphing and solving.

If little Timmy is unable to read the manual about how to do math he doesn't yet know with whatever his specific calculator is, he is at a severe disadvantage, and the teacher basically cannot help him.

A friend in high school bucked the trend and used a casio in our TI based education, and did just fine for himself, but he was apparently a smart kid.

That problem could be solved by creating a 1:1 clone regarding buttons and user interface. But I guess TI has a good legal team to tackle that.

> $160 is what the market will bear.

You previously acknowledged it's a "very captive market" that you "would've expected Texas Instruments to try gouging" :) "$160 is what the very captive market will bear until the state-sanctioned gouging backfires" is a less compelling argument.

"Shrug" is kind of gross. Seems like you're being reflexively cynical.

Edit: to be clear the problem here is really local school boards being antidemocratic and unaccountable, not TI being greedy.

There are plenty of things in the world for me to spend my limited supply of outrage on. Calculator pricing doesn't make it into the top 100.

It is an abysmal value. Your corner drugstore sells an AP/SAT approved calculator for $9 to $29.

I will buy one anyway because calculators remain a modest luxury that I want to indulge.

With a CPU 3x faster than a z80, you gotta wonder how many seconds per python instruction.

156MHz and 3,5MB user memory... Why do I feel like that is a joke these days.. I think some ESP32s are faster and have more memory, but not sure if they are fully comparable...

Interesting that this doesn't seem to include a computer algebra system like the Nspire CAS. Wonder if it's a testing environment compliance thing?

Bring back the HP-10c. RPN with "scientific calculator" label. Pure and simple, and approved for testing that forbids any programmable devices.

EDIT: oops, conflated with HP-35, from a decade earlier. 10c was programmable. HP-35 was not.

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.
