ABSTRACT:
An environmentally sealed, EMI suppressed shock/vibration protected microcomputer workstation is provided by a sealed enclosure of stainless steel having a lower base portion for containing a dampened, spring suspension platform carrying the CPU and electronics, and an upper hood portion for housing the CRT which is removably held in place by a unique arrangement of support pins that cooperatively seat in quick release brackets affixed to the enclosure's interior walls. A front panel of the base portion mounts a stainless steel tactile dome keyboard retained and sealed about its perimeter within a stainless steel casement that in turn is welded to the stainless steel walls of the base portion. The enclosure further includes a labyrinth cable seal assembly for entry of standard flexible cables without need for special fittings, a magnetic disk drive port having a removable marine-type circular compression seal closure, and a fluid port for circulation of coolant to an internal fluid-to-air heat exchanger for removing heat build-up from the interior of the housing.
