Since you already have servo motors and encoders, you should look at my
parallel port motion control set.  See  http://pico-systems.com/PPMC.html
If your servo amps are in good shape, you should not have to buy anything
else.  If your amps need to be replaced, Copley Controls has some good
ones.  This hardware is supported by the next BDI CD to come out, which is
in production now.
