“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!![;)](https://www.osnews.com/images/emo/grin.gif)
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.
