I hear Drew's done some great work with this. I'd look at it myself, but flashing my calculator firmware is a bit risky for such an overpriced device. Thank yo

Thank you, College Board.
- Sir_Cmpwn 10y agoFWIW it's very difficult to brick a calculator without doing so intentionally. The boot sector has a recovery mode built in for reflashing in case of the worst and the boot sector itself is write protected except in some very exceptional circumstances.
- qwertyuiop924 10y agoAh, good. Thanks Drew. By the way, I didn't see any actually, you know, graphing applications in the repos. Those exist, right?
- MaxLeiter 10y agoThey don't - KOS currently doesn't have FP support (although the C library[1] does provide FP, it's not too accurate or fast) [1] https://www.github.com/KnightOS/libc https://www.github.com/KnightOS/libc
- qwertyuiop924 10y agoFP?? I was asking about using the calculator as a calculator. EDIT: Oh, floating point! Now it makes sense!
- dalke 10y agoThere are a lot of used ones on eBay. The devices for all those graduated kids has to go somewhere. Looks like ~$20 for a TI-73, vs. $70 on Amazon, and ~$40 for a TI-83+, vs. ~$80 on Amazon.
- qwertyuiop924 10y agoAh. I always forget to check ebay. Although pre 84+ calculators were a pain to flash...
- hackcasual 10y agoWay back in the day I built a parallel port to 3.5mm jack flasher for my 83
- qwertyuiop924 10y agoYeah, but USB to 3.5 is a bit harder, IIRC...
- hackcasual 10y agoSurely arduino's these day would make that pretty simple
- qwertyuiop924 10y agoYeah, but I don't know how do do it :-(. I'm not so good at hardware...
