    Abstract: Apparatus and method are provided for intelligently controlling an electrical power distributor for a personal computer, its peripherals, and other devices.

The parallel interface can be removably connected through a parallel cable to a parallel port of a personal computer. The single-chip microcomputer has a clock to keep time independent of the personal computer. In response to programming instructions from the personal computer, the single-chip microcomputer controls the relays to selectively connect and disconnect the power lead connector to the electrical outlets of the distributor. Communicating with the distributor is made user friendly by including a software prorgram for the personal computer that translates simple commands from the user into commands sent through the parallel port of the personal computer to the distributor.
