Samudra and the gang,
The bee's knees would be an Arduino Mega 2560 talking over one of it's
serial ports to the pc. Using the output of the Orbitron (or insert
your fave rave software here) DDE server to drive the microcontroller.
There are enough digital/analog pins to drive/slave anything from
there.
Simple serial port setup. Repeatable. Extensible. The chip has several
other HARDWARE (i.e has it's own hardware buffers for i/o) serial
ports for more and more fun stuff.
Have a look on youtube or google for code to drive steppers / selsyns..
