RE: Motor Question
Some of the older "variable reluctance" type steppers don't have the magnetic "detents" you feel on normal steppers. Could be one of them.

No, I am not sure that they are not stepper motors.
They don't have the usuall "click-click-click" feel of a stepper.
I think they came from a larger (older) tape drive which would lead me to
believe that they are in fact steppers.
I am going to keep looking.
It would be nice to find something that did not cost an arm and a leg...
Thanks for your input.
