The Ndless Team devotes itself to open your TI-Nspire to the greatest community programs, OS update after OS update since 2009. We have once again reopened the door for OS versions 3.9.0 and 3.9.1. TI-Nspires sold with pre-built OS 3.9.1 (HW-S) can now enjoy the sweet taste.

If you already have Ndless 3.6 for OS 3.6 installed, stick to it as OS 3.9 doesn’t offer much interesting, and Ndless 3.9 re-installation after reboot is computer-dependent.

Owners of HW-S, grab your can on ndless.me!
