I'm one of those people who believes "there's always a way". There has to be a way to get sound on this device.

With external hardware, sure.
But since pretty much nobody cares, it hasn't really been done.

Exactly. Sound on the Nspire has been done, through both Lua (where one cannot send 0x00 bytes) and native code, but very few people bother.

Built-in sound has been a standard feature of HP calculators for decades... but the tradition ended with the Prime (maybe the slightly older, and far less powerful, 39gII ?), tailored to those silly standardized exam testing restrictions, which has no integrated buzzer.

I'm a newbie in nSpire environment so sorry for my ignorance: it seems like there is no Ndless for 3.9 firmware, but is there some way to install that even after getting this newest OS in your handeld (through downgrade as an example) ?
As I am very interested in nPDF and I'm trying to figure out if it can be installed

it seems like there is no Ndless for 3.9 firmware,

Indeed.

but is there some way to install that even after getting this newest OS in your handeld (through downgrade as an example) ?

If the OS was installed the normal way, no easy way. The anti-downgrade protection was raised to forbid downgrade to OS versions older than 3.9.x.
If your Nspire is old enough (all Clickpad and Touchpad, CM-C, CX older than hardware revision J), downgrading the boot2 through the RS232 TTL port, and using nLaunchy, could do the job, but that requires extra equipment. If your CX CAS has hardware revision J or newer, no joy.

I installed 3.9 by the student software, it seems like nPDF will be forbidden to me ... how do I know which hardware revision is my CX CAS ? Do you mean that alphanumeric code written on its back ? mine starts with P and ends with L ... so does anybody know if Ndless for 3.9 is set to be worked on and/or will eventually be released in future ?

Bonjour,

J'ai un soucis en branchant ma TI sur l'ordi, elle a été mis à jour sur l'OS 3.9 et je voudrai installé Ndless 3.6.
Mais cela marche pas. Donc j'ai voulu reset ma TI et mettre l'OS 3.6 mais j'ai un msg me disant "impossible d'installé un OS de version précédente à la version installé alors que la TI est "rest".
Une idée?

Yes, you have hardware revision L.
Which means there is no way to go back to 3.6 for now, even for me.

Unfortunately, I have no news from this.

C'est hélas normal, TI interdit le retour à une version antérieure.

Bonsoir!
J'ai une question, j'ai une Ti-Nspire CX version 3.1.0.392 et j'ai la lettre P-XXXXD. Puisque mettre Ndless 3.6/3.1 sans problème?

Cordialement.
Kohta.

Oui, aucun problème
