CAS OS on Standard TI-nspire [development idea]
« on: March 03, 2010, 08:25:11 pm »
I was wondering if you would ever be able to port the nspire cas operating system to be able to be installed on the normal nspire. If you ever could that would be awesome :)

Now that you mention it, if both models has the same hardware, I am fairly certain it could be possible to patch the OS (or hack it, or do some other stuff) to load it on any model. The only problem, though, is that I am unsure about how stable the CAS OS would be if someone put in the 84+ keypad, since the CAS has no 84+ emulation...

Btw welcome on the forums :)

I think I saw some GIFs of Ndless installing OS image files somewhere on one of the French forums. It seems like its possible but would run into legal issues.

I am not sure if the patch to do it would be illegal, though, if for example it contained no code from TI products

But TI certainly wouldn't like it, maybe enough to cause us trouble. Then they might start sending DMCA notices again (according to Brandon Wilson on UTI, TI does not like people modifying their software).

It is more like replacing their software. ;)

I would be cool to have the TI-84+SE emulator to CAS calculator. It would be nice to some that want to backup stuff of TI-8x family.

What I think is that if they sent DMCA notices, the EFF would fight back again and TI would end up epic failing again, like what happened with the keys.

TI might have some ground on this one though -- this would be stealing software that actually costs something (I know the .tnc upgrades are free, but they require the upfront cost of a more expensive calculator)

Maybe. But I think that since they provide us with the entire OS, I suppose we can do what we want with it, except for distributing it.
Even though putting CAS on the non-CAS one might be considered stealing, I don't think TI can do much about it.

They can do things to the people who release such a hack, I think.

I think it's a bad idea because it will make the Nspire Non-ACT. This will get TI really mad, mad enough to actually do something about this kind of dev site rather than just a halfhearted letter. If you really want CAS, just wait for the 89 emulator! It already does it just fine, and no calc modding is necessary! (besides ndless of course)

Whether you can use it on a test has to do with the key layout, not the capabilities.

The ACT uses capabilities to disqualify it so yeah it would affect that test but not the SAT.

Edit: yeah I had it backwards, fixed

Not in the case of the ACT (TI-89 is not allowed, despite the fact that it has no qwerty layout)

Edit:
JonimusPrime, I think you have it backwards

Yeah, he has it backwards. CAS is allowed, as is the 89, on the SAT, but not on the ACT as it only goes to Algebra 2 for the Math section. Keyboard layout is an issue on both., although I can't really see why. Why does the key layout affect whether it's allowed or not, is what I wonder.

Anyways, I still maintain it's a bad idea, and I don't want to be sued for it! plus, I'd like for my nspire to still work for the ACT, at least for two more years. After that I don't really care, cause I'll be in college!
