This only works on Mac Plus and 512KEnhanced.  This magic number is
the actual address of the exitToShell routine itself in ROM, and it is
different on the SE and II.  I don't have my stuff here and can't tell
you what it is for the SE (but it is different) -- but it is better to
use the trap itself, which is machine independent.
