SI-7300A or SLA7024M CIRCUITS

HI,
I have obtained some stepper control chips off HP
laserjet 2 and a Fujistu printers. Both chips look
quite capable of handling a reasonable amount of
current.

Has anyone had a go at using either of these to create
a stepper motor driver circuit. It seems a shame not
to make use of these bits as the motors they control
are worth trying in a mill.

Thanks.

Tad.
