A full and Half wave stepper motor controller for 2-phase hybrid unipolar stepper motors. The circuit uses the STK672-110 hybrid chip from Sanyo and 7 external simple components. The speed is controlled with the frequency of a pulse signal, while the rotation direction is controlled with a single wire.
Is it possible to buy the chip and connector (or DIP version) ? I did a bit of searching but found only large quantities for sale.

@vince086 the chip comes in SIP 2mm spacing package and not DIP. Did you search in ebay for this?
