That's tantalizingly vague.

So if I were to try to disassemble the 42S ROM, I would find the floating-point routines in machine language, I guess, and perhaps the complex and matrix functionality as well, and the graphics primitives? With the command line interface, menu system, program editor, and program interpreter in (compiled?) RPL? Am I warm? Has anyone delved into this and written any articles about it?
