Open computer system with externally interconnected peripheral modules

In an open computer system comprising a chassis having a first side and an opposing second side, an aperture in the first side for receiving electronic modules, a bus disposed within the aperture at the second side for providing power to electronic modules, a plurality of bus receptacles disposed on the bus for connecting electronic modules to the bus, a plurality of guides disposed within the aperture for receiving electronic modules and aligning them with the receptacles, and a module having an intelligent controller and adapted to be installed within the aperture so as to present an interface port accessible from the first side of the chassis, a peripheral module, comprising;

• a housing adapted for sliding engagement with one or more guides and having a module connector for engaging a receptacle, whereby said peripheral module is repeatably installable in and removable from the chassis;
• a peripheral device disposed within said housing, said peripheral device including electronic circuitry, said electronic circuitry being electrically connected to said module connector for receiving power from a receptacle;
• a front panel which is accessible from the first side of the chassis when said peripheral module is installed in the chassis;
• and
• an interface port located on said front panel, said interface port being electrically connected to said electronic circuitry of said peripheral device whereby said peripheral module is externally connectable to the interface port of the intelligent controller so as to communicate interface signals therebetween.
