When the button is pushed, it sends a signal via parallel port to a set of relays that serve as the power button to the main computer and move the KVM to the primary box. When the primary box shuts down a normally open relay closes and moves the KVM back to the powered off box.
told you kind of overboard as you need basically a micro computer to function as a power switch.
Could probably be done with an Audrino board... but that is way over my head.
