That is a four phase unipolar motor, which means that two windings are usually activated at the same time. The current per winding = 24 V/75 ohms = 0.3 A, power per winding = 24^2/75 = 8 watts (roughly). A very simple four transistor unipolar stepper driver will work fine. The motor will run on lower voltages but provide less torque.
You will have to determine the order of winding activation by experiment. For reference, see this Jones on Stepping Motors
