Yes, exactly that.
It evolved from need to control mount with couple of controllers, because at that time I was using Mel Bartel's system, running on PC (whole motherboard then, Fujitsu st1000 now), and I wanted something more portable... so I started to experiment, keeping the common parts (motors, Pololu drivers) and interface (STEP/DIR pulses) in the mount.
Currently I am using OnStep, but other systems are also OK.
Attached is the schematic of the motor driver, mounted in the EQ6.
