Probabally could be done with any step/dir. drive amplifier.
The circuit to drive it using a 555 pulse generator with a Push-Button to a flip-flop to start it.
The output of the 555 to a decade ripple counter like a 7490 or similar with a carry out to a 5 pulse ripple counter, the output would be 50 pulses (90°)
the 5th pulse out to reset the flip-flop stopping the 555.
Direction could be done several ways or simply by a direction switch.
