The five miles of conductor around the house terminate at a telephone punch panel and are fed (via the ribbon cables) into data acquisition hardware on a PC. Also shown are a speaker control board (upper left) and a microcontroller for the lights, electric outlets, and fans (lower right).

The PC is connected via a serial line to a DEC alpha, on which the neural network and control software run.

An old NeXT serves as the voice of the house, connected to the DEC alpha via by ethernet and connected to the rest of the universe by a dedicated SLIP connection.
