Abstract: A system and method for converting a desk-top computer into a rack-mounted computer includes mounting the chassis of a desk-top computer in a carrier tray. The carrier is then mounted in means for sliding the carrier in and out of an electrical equipment rack.

Abstract: A system for customizing computers to mate with an array of wire or cable terminus connectors includes a detachable wire or cable terminus connector mounting assembly. The wire terminus connector mounting assembly includes a cover plate and an interfacing circuit board. The cover plate may be customized to present an array of selected computer-based connectors which are electrically connected to the computer by the interfacing circuit board which includes a standard connection array at a predetermined location.

Abstract: An enclosure for a computer system is disclosed, which has the capability of being used in a desktop, tower or rack-mount configuration. The enclosure includes side extrusions having a center portion and two end portions which are substantially perpendicular to the center portion. Foot grooves are located on the end portions and on the center portion near each corner, and center grooves are located along the wider center portion. Pliable feet may be slid into position into foot grooves of the end portions of both side extrusions, in the desktop configuration. The tower configuration may be obtained by installing support feet which wrap around the corner of the side extrusion, mating in both the foot grooves on the end portions and those in the center portion of the side extrusion. The disclosed enclosure also enables rack-mounting by way of rack slides mounted into the center grooves of the center portion of the side extrusions.

Abstract: An expansion system for a bus-architecture system is disclosed, particularly for an SBus-compatible system. The expansion system includes a host expansion board which fits into one of the expansion slots connected to the SBus, a cable connected to the host expansion board, and an expansion chassis connected to the cable. A memory management unit is included in the host expansion board, for mapping physical addresses on said SBus into addresses of add-on functions installed in the expansion chassis. This mapping allows for varying memory size functions to be installed into a single expansion slot. The MMU also copies the ID PROMs from each of the add-on functions into RAM on the host expansion board, so that such expansion is transparent to the driver software.

Abstract: A computer system comprises a storage device comprising a plurality of locations for storing data and having a defined audit partition region comprising one or more of said locations and processing circuitry for detecting access requests to alter data on respective sets of one or more of locations of the storage device. Responsive to each access request, the processing circuitry stores data from said respective set of locations in the audit partition region prior to performing the access request, such that a sequence of data transfers from the storage device is stored in the audit partition region in a known order. Responsive to a user request, data is restored from the sequence of data transfers in the audit partition region to the respective set of locations on the storage device to return the storage device to a previous state.
