A mobile computer workstation includes a base assembly including a plurality of wheels, an adjustable column assembly mounted to the base assembly and adapted to support a computer monitor, and a camera configured to communicate a video signal, the camera being mounted on the workstation such that a line of sight of the camera is directed rearward from the computer monitor. The blade formed at the distal end of the outer sheath is directed oblique to the circumferential direction of the outer sheath. In response to the enable bit and the at least one sub-channel select bit, the control logic selects one or more of the address signal lines to capture independent address information to support independent sub-channel memory accesses into the memory array.
