Hmmm... this thread ran off track quickly. :)

Let me clarify that I am not looking for a stepper *driver* (which  
takes step & dir signals and converts that to amplified H-bridge  
outputs to drive the motors), but I'm looking for a motion controller  
that will take vector commands and generate step & dir signals with  
appropriate acceleration and decceleration signals.

I have separate drivers already, but want to relieve the PC from  
having to generate real-time step & dir pulses.

Cheers,
-Neil.
