Older equipment (especially 1/4" sound recorders) were not capable of running at crystal sync speed right away. For this reason, they actually had a tiny flag that would appear in a see through window a moment after the recorder was activated. The recordist would not yell "speed" until after the flag would be visible (since only after this moment the audio would be capable of being in perfect sync with a camera).

or, "minus optical soundtrack"; the origins of "MOS" are apocryphal. Also, what school did you go to?
