Electrostatic storage tube

ALL COMPUTING machines and information-processing devices require some type of storage. Analogue computers have information storage scattered through the machine as part of the computing elements. For example, an electronic analogue computer might have a simple resistance-inductance-capacitance computing circuit whose basic storage would be twofold. The instructions for the type of computation would be stored in the interconnections of the resistance, inductance, and capacitance components. The initial conditions and partial and final results would be stored as current and voltage in the components of the computer.
