Hi!
I used to have a Pentium 133 driving 6 Steppers and they run quite well at a
steprate of a kiloherz. This really loads the system. It would be a nice
thing to have a microcontroller receive digital position input from the
parallelport and generate the steps.
I guess this is just what PPMC does.
