Abstract
By providing an input/output module which incorporates post means formed thereon and slider means connected thereto and movable into and out of locking engagement with the post means of an adjacent module, a unique input/output module is achieved that is rapidly mounted to an adjacent module as well as rapidly disconnected therefrom. Preferably, each input/output module incorporates mating connector means positioned on opposite surfaces thereof, whereby each input/output module electronically directly connects to an adjacent module for communication with a central processor.
