After
Ndless 1.1 prototype and
Ndless 1.2 prototype, Bsl and me are releasing another Ndless version based on
Ndless 1.1.1:
Ndless 1.2.
You can now run assembly programs on production Nspire with OS 1.2 too.
It might be of some little use to you, as some Ndless 1.1 programs have never been recompiled for Ndless 1.7/2.0 and as OS 1.1 is nowhere to be found on the Internet.
Upgrading to Ndless 1.2 might get rid of the famous power bug too.
