“Punix is a Unix-like operating system for the Motorola M68000-based TI graphing calculators, starting with the TI-92+. It is currently under development and is not ready for widespread use yet. So far the kernel is being written, and user-space utilities and applications will follow.” …amazing.
Too bad they don’t support my TI voyager 200 and NSPIRE-CAS 2010, I could run my Linux apps on those! Oh, wait I have a smartphone for that.
But really, nice job! Given the age of the device, it might be a little impracticable, but it is so cool. Engineering for the sake of engineering should become a law.
Funny that you should mention your V200. I plan to support that and the TI-89 Titanium, in addition to the TI-89, because they’re similar to the 92+.
On the other hand, the nSpire has completely different hardware, so I won’t support any of those models. They’re a lot more powerful and have more memory than the TI-9x series, so I suspect they could even run Linux if someone wanted to port it to them.
The nSpire series seem to be ARM9, so yeah – if it’s possible to bodge the code on to them and they have an MMU, it should be entirely possible to run linux (or a BSD, or perhaps minix) on them.
edit:
Also, having now read a bit in your blog: That’s really quite impressive. I like the “drag the parts I need out of random older UNIX and *BSD systems and reshape them”-approach.

Is the ti-92 not supported due to ram constraints?
And now I need to get another 92+ (I should never have sold mine after college). This is awesome work, I wish you the best with it!
graphing calculators suck unless you are smart. get the hell out of town
those are not “graphing calculators”, they are CAS. Graph calc like TI-83 and 84 don’t even have a % of the features the CAS ones have.
Which is funny, considering that the HP-40G is a tangible proof that you can make a CAS run okay on weaker (and cheaper) hardware than a TI-83+.
Market segmentation is something beyond logic. I am impressed that it even works.

Calculators are special, since many countries require specific models on their curriculums.
For example, in Portugal Casio has always had a preference to TI.
The FX-850P and FX-880P were very loved in the early 90’s.
i really miss the calculators from the 90’s… i think industrial design had a peak back than…
anyways, here is a link to a collector:

An m68k-based graphing calculator? That’s AWESOME.
