The "S" was also the first to use position sensors on pan/tilt to recover from being bumped. The "M" does not, and if it gets bumped, it's rehome time . . . . If I recall correctly, the logic board uses the sensor input and lamp supply feedback to determine what version it's on, since the "M" and "S" logic cards and software are identical.
