@load-rom ( filename* -- )
(
Attempts to load the ROM from filename* and executes it. If the file exists
and has non-zero length, this function does not return, because the new ROM
is executing in its place.
The screen and both stacks are cleared and all the device vectors are
written to zero as a convenience. All other device bytes are left
untouched, so they could introduce a device state to the next ROM that
it's not expecting.
