I&#x27;m not releasing the kernel or graphics library code for the moment (it&#x27;s not finished, for one thing), but application sources will be available and drivers, etc, will all be open-source. The fixed 16KB banking window is a pain in one respect, namely that applications (which themselves are relocated into the banking window) cannot directly access MALLOCed RAM. Of course there are ways around this, but I was a little envious of the more flexible banking schemes on some of the Z80 platforms described in the SymbOS developer docs. But it&#x27;s also fun working around the Atari&#x27;s limitations.
