darlington driver help

Hi folks, just getting back into electronics, not that good with analog theory (more into digital stuff) and have a question about a uln2064b.

I have used (years ago) a 2003 darlington driver, but a bit lost on the datasheet for this 2064.

How to connect it to controll a stepper motor from a pic.
What pins connect to what (not even sure what the K is on the datasheet!)

A simple schematic would be helpful, if anyone has one
(I would be using a pic12f675 with some in4007 diodes as I have a load of them, and a old fruit machine (slot machine) stepper motor)

Can handle the programming of the pic, and figuring out the stepper wires, but not sure about how to wire up the 2064 to stepper and diodes +v -v etc

I will be getting some 2003's but dont want the 2064 to go to waste

GND pins to circuit ground, K to motor supply, outputs (C) to coils. inputs (B) to PIC. (unipolar motor)
