George,

You're not missing anything; I've just been unclear.  I have shot an OM-2S
with film in auto mode to record fireworks.  I've also coordinated this
simultaneously with a bulb shot on the OM-1. In relation to itself, the
OM-2S is taking an exposure in auto mode.  In relation to the OM-1, the
OM-2S is providing info on the length of the OM-1 exposure, i.e., acting as
a "meter."
