I have some stepper motors and all the boards that came out of a Calcomp plotter. The steppers have a circuit board mounted to the back of the motor and I am assuming that these are the driver boards.

My question is, is there a website where I can get the information about these drives in order to use them? I have the original power supply and the motherboard from the plotter too as well as two cooling fans.

My son is wanting to build an engraving machine for his science fair project this year and I thought these might be perfect for that.

Any help would be greatly appreciated.
