    Abstract: A byte-swapping circuit is provides for interfacing PCI systems to VMEbus systems. The circuit allows the PCI bus to selectively enable or disable byte swapping whether the VMEbus system is in master mode or slave mode. Also, the circuit delays the assertion of the DS0/DS1 VMEbus signals until after the byte swapping circuit has completed its operation, thus avoiding violations of the VMEbus timing specification. Finally, the circuit optimizes its performance during block transfer operations by maintaining its byte-swapping configuration constant during each bus cycle in a given block transfer. Thus, the circuit configures itself for the first bus cycle, but eliminates the reconfiguration delay for each bus cycle afterwards. The circuit can also byte-swap data bytes being transferred on the address bus during multiplexed block transfer cycles.

    Abstract: Transport brackets are affixed to the container and include provisions for achieving transportability with either a crane or a fork lift. Variable storage capacity is provided by an extension bin which is detachably affixed as part of the container. The top and bottom of the container are compatibly configured to provide an interlock between a plurality of stacked containers and a dolly is configured for use with these interlocking provisions. The container is configured to achieve stacking interchangeability when any vertically peripheral sides are aligned and brackets are disposed around the vertical periphery of the container to achieve fork lift accessibility from any direction perpendicular to the vertically peripheral sides.
