So the yellow signal cable is unused? I suspected this.

Oh. I should have mention that this project is to show the power of Linux, so I SHOULD have little to worry about the OS being unstable. However the operating conditions could get kinda rough. 100 degree Virginia days are not exactly the best operating conditions for a PC, although the water cooling system should take care of this.

Due to the fact that I am using Linux I think it will be easier just to use a printer port to control the Victors, as the USB kits do not seem to offer Linux drivers(no surprise there). From what I have read a parrallel port should allow me to control 5-8 servos or Victors, is this correct?
