[sci.electronics] Stepper Motor Drivers

stevel@chamber.caltech.edu (Steven J. Ludtke) (08/19/90)

Our lab has an x-ray diffractometer with 4 stepper motors to drive the 4 axes.
The controller for these motors is ancient. Rather than waiting for it to break
at some critical moment we'd like to hook it up to be controlled by our lab
computer (an Amiga 3000). I haven't found any amiga-specific stepper motor
control boards, but I can get an HPIB interface. I'm looking for a controller 
that uses this interface. Barring that I'd like to find a general purpose 
stepper motor contorl board and I'll build the interface myself. Or, the worst
possibilty, get a couple of IBM stepper motor control boards and use them in
the IBM slots on the Amiga (I'd like to avoid this, besides it's expensive).
Any suggestions ???     Please reply via email. Thanks
