Abstract: A cabinet having special utility in patch panel-formation of electric cirts in analog computers. The patch panel is removed from the computer and mounted in an inclined attitude atop the cabinet for easy viewing of circuit holes in the panel face. The cabinet includes cable-storage trays in close proximity to the patch panel, whereby the technician is able to readily select an appropriate length cable for plug-on connection to the panel, necessary to form various electrical circuits. After the panel has been wired it is remounted onto the front face of the analog computer; the cable terminations extend through the panel into electrical connection with terminals permanently located in the computer.
