[sci.electronics] stepper motor ???s

I recently went over to an electronics supply store and noticed some
spare stepper motors.  Well, I came up with an idea but I'm no
hardware johnny. So, I need some help.  My most fundamental question
is the stepper motor seems to have 2 halfs.  A top and bottom.  Both
halfs have 4 wires coming out of the case.  I know 1 is going to be
the ground but what about the others.  How do you figure out what
is the proper voltage?  How do you determine how to reverse the motor?

Is there anything else that I might be missing?

Thanks
