OMG I can't believe it, they finally did it! Somebody made a graphing calculator with ~modern hardware and got it approved for use in exams!
I've been complaining about TI being able to sell their _ancient_ tech at new prices for so long. I hope TI never moves another unit
Interesting design decisions like: it has only 256KB of RAM! Software runs on bare metal without a third party kernel.
Code is CC BY-NC-ND, so not Free, but less user-hostile than I was expecting.

numworks.com posts the BOM, datasheets for all the components, schematics and gerbers for the PCB, .STL files for the case, and walks through how to compile the firmware yourself.
that seems so inviting to tinkerers I think the no-derivatives license must be either a mistake or a compromise.
If not for the license this could be not just a better graphing calculator but also a great platform for learning about computer hardware and embedded development!

@pho4cexa I'm surprised they don't have the relevant xkcd on their home page. https://mastodon.social/media/-w-5m3LvnVa7kO3bp3g
