Photograph of RW-30 digital airborne computer, completely transistorized, showing subminiaturized packaging techniques and silicon circuitry, ca.1955. A man wearing a suit and spectacles is holding what seems to be a box with rows of circuit disks(?). A second box, which is located directly in front of the first one, displays two rows of circuit disks and below these, what appear to be small drawers are observable; two metallic handles and input switches are visible on its top.; To the right, a third box is visible showing the same type of input switches and metallic handles; several knobs are visible on its side. In the left, a fourth box is visible with rows of circuit disks on its top and it shows a large knob surrounded by cables which seem to be connected to the box. All objects are sitting on a table and a light-colored wall fills in the backdrop.; Photoprint reads: "Subminiaturized packaging techniques -- the RW-30 digital airborne computer is completely transistorized, and subminiaturized packaging techniques and silicon circuitry are used throughout. The new control computer combines computation speed with reduction in size, weight and power consumption. The complete computer has a volume of 4.19 cubic feet and weighs only 203 pounds. It consists of four separately packaged units--magnetic drum storage unit, arithmetic and control unit, input-output unit, and clock generator and power supply unit. It was developed by the Ramo-Wooldridge Corporation under contract to the Air Arm Division of Westinghouse Electric Corporation".
