PTT aside, something scares me in this:

Notice point #2. I wonder if this could mean that as soon as you update the computer or student software to 3.6, it will no longer allow you to send softwares between the calc and the computer if the calc is running an older OS? That would be one more way for TI to force people to upgrade.

Granted, you could maybe uninstall 3.6 software then reinstall an older one, but what if the student software writes something inside your Windows registery to prevent installing older versions?


I hope that nobody tampers with the teacher mode on the HP Prime.


Back on the PTT issue: Even if TI wants to block it and Ndless, I still don't see PTT security as an excuse to prevent students from downgrading the machine they spent $150 on. At the very least, they should encourage schools to ban older OSes from exams but still let people downgrade, in case they want to use an older OS during their non-exam times or free time.

@DJ Omnimaga: Apparently, no problem with wired connectivity.
It's only for wireless connectivity that if you use 3.6, it has to be on both sides: OS and software.

Registry editor?
Also, re-install windows?

Ah ok, but now that they're doing this, IMHO it's only a matter of time before it's extended to wired connectivity kit too. They're that bad and I wouldn't be surprised if they did something about people switching the Nspire motherboard to get around the 3.6 lockdown in the future, even if it meant a complete redesign of the calculator case.

I found this in a Chinese forum

TI-NspireCX-3.6.0.546.tco :

Can I upgrade my CX CAS from 3.2.3 to 3.6?
Will my CAS software(ver 3.2) will recognize my CX CAS?

Thanks for your findings! But as we are saying with each release, don't upgrade yet as you would no longer be able to use Ndless if you want to and we're not really sure the 3.2 software will work with OS 3.6. (You can upgrade if you don't care, there's nothing to keep you from doing this, but you probably won't be able to downgrade back to 3.2.3 after.)

EDIT: Actually, the 3.6 software is out.

I tried to install Computer Link 3.6 and connected with my CX CAS 3.2.3.1233,
it works fine.I don't know if I got 3.6,can I use the CAS Student Software 3.2 to connect with.
Since I can only see the non-CAS student Software posted

Refer to this post:

The one I need is CAS student software,but I downloaded the student software,
but it is non-CAS

In the post,it said:
"each edition of TI-Nspire software contains two versions of the software, CAS and non-CAS, each with separate and independent evaluation periods which will start on the first launch of its version"

I'm confused that the Student Software now,does it merge both non-CAS and CAS into 1 installation file?

OK,I installed the "TI-Nspire software Student Edition",it clearly shows that it doesn't contain non-CAS and CAS in the installation file,my version 3.2 CAS software still exist,so I think I better wait until the CAS 3.6 software out,then upgrade the calculator OS.

Connectivity tested:
Calculator with OS 3.2 can communicate with Software 3.6

Same goes with the Computer link Software.
