There's the NumWorks which is very similar for a more reasonable price, that also run Python

I'll take my father's HP 49g to my grave. but if TI wanted to flirt with me, all it would take is a setting to enable Reverse Polish Notation. (I did check the features, and no mention).

It's a beautiful device so much that hacker inside me wants to poke into what CPU they have and design a similar one in Verilog myself then put it on FPGA with similar display and it's driver then a 3D printed case and keys too.

I still have my TI-83 plus. It's been with me for 25 years now! I've always kept it on my desk, despite the fact that I engraved 'KoЯn' on cover when I was 13 or 14.

This has me pining for a future professional class CAS 3d graphing calculator.

I'm thinking something that could be a major upgrade in spirit to the long-in-the-tooth (released a decade ago) Casio FX-CG500.

Could use the soon to be released ARM C-1 Nano and Pro cores in an SoC with stacked 2GB LPDDR4, USB-C charging to a large battery, high-res transflective LCD...

Shout out to https://ticalc.org/ - the design is pretty much unchanged.

Why do you need an online calculator subscription? I can kind of get why you want a physical calculator, especially for a school environment, but why would you want a calculator online when you can just use... the rest of the web?

I didn't have a calculator until my senior year of highschool. But since we weren't alliwed to use them in tests, I didn't feel like I was missing anything.

As an engineering student at CMU, I had an HP 15c like everyone else. A few years back when I found out they are coveted, I sold mine on ebay. I have an emulator on my phone.

I assume that calculators will continue to evolve and that my grandchildren will have a Propædeutic Enchiridion.

My ti-82/83 got me into programming because I hated math so much that I taught myself to code an app that would help walk me through how to do various problems. I got in trouble but it was worth it.

Also, drug wars, x wing vs tie fighter, and all sorts of other awesome games were definitely the fun thing to do with these.

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
