 - Compare features with existing implementations and other brands
 - Get filesystem access (open etc) with the POSIX interface
 - Get a decent amount of RAM not just the fixed 32 kiB that's hardcoded so far

   * Try and provide a font smaller than 5x7 for more compact shell on mono

+- A decent keymap that can input all relevant characters into the shell
 
 Future wishes:
 - Build for fx-9860G II (requires manual filesystem support)
