a spinning drum with two electromagnets inside. Essentially, the CPU
activates a pair of windings on these magnets leads as necessary to attract and repel the drum to pull it round and
display as appropriate. To attempt to visualise the rotation effect, take a look at the compass rose below, representing a side on view of the reel,

For sake of accuracy, we're representing all possible phases of the motor, effectively moving the motor one half step at a time, so a 48 step motor becomes
96 half steps. This is necessary because of some programs running the wiring in series with a distinct delay between the pair being completed. This causes
a small movement that may trigger the optic tab.
