Abstract: A microcomputer system facilitates the connection of peripheral devices to a computer unit with a plurality of external ports for connecting to external peripheral devices. In one embodiment of the invention, a set of adhesive strips is attached to positions adjacent to the ports. Each strip in the set has a distinct color. Another embodiment of the invention includes an adhesive strip having a plurality of color coded regions, each of the color coded regions being placed adjacent to a separate one of the external ports. The microcomputer system also contains at least one peripheral device. The device is designed to be electrically matched to one of the ports In one embodiment of the present invention, the peripheral device contains a cable and a plug. The plug has a color which is substantially the same as The strip color associated with the matching port.
