The L298 & L6506 stepper motor chipset

I've been working on repairing an RMV Sport 232 stepper motor controller.

Like many controllers this one uses the L298 driver:

Which closes the current feedback loop with the L6506:

A very interesting chip set and i'm sure it is ubiquitous in all things stepper motor.
