You still seem to be projecting a degree of hardware dependence on the
language ROM that is BASIC which just doesn't exist - the MOS deals with
all that sort of stuff. I've used the normal BASIC2 ROM in a box which is
almost, but not completely, unlike a real BBC/Electron.
Ok, BASIC of course relies on some aspects of the MOS which does require
hardware (keyboard, screen etc.).
Ignore BASIC, concentrate on what the MOS requires.
