    Abstract: A personal computer includes a frame unit and a top cover mounted to pivot on the frame unit. In one version of the computer, the top cover pivots upward and outward to the rear of the system as it is opened. In another version, the top cover pivots upward to the side. One or more DASD storage devices may be mounted to extend downward from the top cover. A planar board is attached atop the lower side of the frame unit, where flexible mounting hardware allows the attachment of one of several types of planar boards. A central support structure includes a riser card plugged into a connector of the planar board, and a number of card connectors into which option cards can be plugged for electrical connection with the planar board. The central support structure also includes a bracket extending along the rear of the computer, having slots through which port connectors of the option cards can extend. The central support structure is held in engagement with the connector of the planar board by the top cover when this cover is closed. When the top cover is open, the DASD storage devices may be easily replaced, the central support structure may be unplugged from the planar board, and the planar board can be easily replaced or serviced. A front surface of the computer includes a door, which is opened by rotation outward and downward, to be slid inward, providing access for the replacement of media in the storage devices. This door and the top cover are separately lockable using a multi-function lock.

    Abstract: An improved planar support structure for a planar (22) of a personal computer system (10) is comprised of an integral structure (28,30) having a plurality of connector support frames (48). The planar support structure (28,30) is interposed between the planar (22) and a supporting structure (36) and securely fastened to each. Each frame (48) surrounds the perimeter of a corresponding connector (50) of the expansion slots (24) on the planar (22). Each frame (48) supports a connector (50) to prevent the connector (50) from flexing the planar (22) when an adapter board (32) is inserted into the connector. Additional alignment pins (44) associated with the planar support structure improve ease of assembly during construction of the system.

    Abstract: A personal computer system unit has a planar card (10) upon which is mounted a processor card (10). The processor has mounted thereon those components, except for system memory, which are most likely to be replaced for a system upgrade. The processor card (10) has a printed circuit board with printed circuits thereon that terminate along one edge at contacts (176). Two aligned edge connectors (100,101) are mounted on the planar board (50). One connector (100) has a key (173) which engages a slot (169) on the edge (48) of the processor card (10) to align the many contacts (176) with contact arms (186). Two levers (210) are mounted on the card (10) and cooperate with frame elements (201) to insert, extract and latch the processor card (10). Each element (201) also has a guide to align the processor card (10) for insertion into the edge connectors (100,101).
