#1 Write local assembler.

[Maarten Hofman]

It would be nice if the system had a cartridge that
would contain a text editor that could edit text(s)
stored on that same cartridge, which could then be
assembled to a fixed location which could be executed.
Basically this would involve:

1) creating a text editor (e.g. a line editor, of which
the lines are stored in a linked list)
2) creating a file system to store the text files on
the cartridge (though it can start with allowing only
one text file)
3) creating an assembler that can assemble the text
file into bytecode and store it at a fixed location
4) creating a method to select between the text editor,
the assembler and running the assembled code.
