The ndless source code?
https://www.unsads.com/scm/svn/nsptools/Ndless/trunk/

Is it Ndless 2?
I have to compile it first, so I have to go to linux first... don't want to do that

Name and password are guest, I found it on a forum

Ndless itself works fine, but is it normal, that I have to do a full reboot after I shut down the clalc?
Wenn I turn him off, and on again, I can't see anything, but on the Computer (via screenshot print service from the TI-Nspire Link software) I can see, that it is on.

So when I open the keypad, put out a battery and bring it back, turning on the calc. I can see it and play or whatever...
(Sry for the bad english, it's not my motherlanguage )

Edit: On my sisters nspire works everything fine, on the one of my friend is the same problem...
