Abstract

Abstract An expansion device is provided having two expansion cards interconnected. While the first expansion card of the expansion device conforms to the footprint requirements of the PCMCIA, the second expansion card ranges in size. The expansion device integrates into the overall configuration that conforms with PCMCIA card architecture. A connector releasably attaches the two expansion cards together. Once attached, the expansion card acts as a slave card to the master PC card. Alternatively, the first expansion card can be used by itself as an expansion device. Guide pins are provided for guiding the attachment of the expansion cards. The guide pins, in addition, provide an electrical ground from the PC card to the expansion card. An adaptor is also provided with the expansion device for providing an electronic interface between a host computer and a transmission media line.
