Ha! Preemptive multitasking and a rotating cube as a demo. Nice work. Would love to see this ported to something else constrained like the Pebble Watch.

I like the ?sneaky-repost ;)

I can see this being used to cheat in exams ;)

The facilities of the TI are generally usefull for that.

Which is why TI added a key combo that erases the memory.

Except most teachers only cleared the RAM because they didn't know any better, so you could "archive" whatever you wanted in the flash...

I wish there was an open-source OS supporting phones like Nokia 1202 http://www.gsmarena.com/nokia_1202-2573.php or cycle computers http://www.sigmasport.com/en/produkte/bikecomputer/topline_w... - tiny devices with dot matrix displays and traditionally limited capabilities.

I thought it's never going to happen (unless I get wealthy and support creating such a device, of course) but this one is close.

You certainly could replace the memory chip of whatever device you want. Chances are, as long as it has a few necessary components (or code to emulate them) Linux will run pretty well.

Holy heck, an in-browser demo. I've always wanted to try KnightOS but the TI-Nspire steadfastly refuses to run it.

You're in luck!

Neat. I sold my TI-84 Plus in favor of a HP RPN calculator: It's not really comparable, but there are more open source projects around calculators like the WP34s[1] project which turns a cheap HP business calculator (HP 20b/30b) into a RPN calculator with a lot of features.

I'd just love to see a solid open-source standard graphing calculator app for the common tablets - something like a more user-friendly version of gnu octave or something. The vendor lock-in by the education industry and TI is absurd.

Seriously, the few times a month I need to crunch numbers I reach for my phone, then get frustrated and just use Google because my TI83's batteries have been dead for years. I don't know what it is but I haven't seen a touch calculator interface anywhere near as good as a standard graphing calculator for just banging out some computations.

This makes me so sentimental. My parents did not let me have a computer when growing up, but they did let me have a calculator. So I did what I had to do to buy a ton of them (TI82, HP48GX etc). At some point I purchased a TI92 but when reading about that now I see it was classified as a computer and not a calculator.

@Sir_Cmpwn, you should document somewhere that at least the TI-83+ ROM will run fine on Android using the Andie Graph emulator. :)
