[Discuss] Open source Propeller microcontroller

[FarMcKon]

Oh man;

The propeller is awesome, but when I tried to use it, I could find
little or no docs (this was what, 5 years ago)? Hearing you are open
sourcing it is pretty amazing.  The mulit-core was rocking, but some
debugging and tweaking was tough due to the limited (or lacking)
documentation

David; Awesome move!  I'm going to go dig out my old propeller, and find
some time this weekend to tinker around with it.  

Hack on;
