Hello fellow Walruses!  I'm new to this community and this is my first project!  I managed to download Ndless 3.6 onto my TI-nspire CX calculator.  Now I'm looking for help to download the CAS OS.  I noticed under Ndless apps https://ndless-apps.org/ there's a file called NCalc with the description "Native access to the CAS engine," does this mean it's a download for the CAS OS?  I also noticed it won't give me the option to download this file.  Any Walrus friends willing to help a new walrus on the block?
