Dynamic circuit techniques used in SEAC and DYSEAC

All the high-speed arithmetic and control circuitry of an electronic digital computing machine to operate at a pulse repetition frequency of one megacycle can be built from just two types of etched-circuit plug-in packages. One contains a tube, a pulse transformer, and a set of germanium diode gates and buffers; the other contains lengths of electrical delay line and diode-resistor termination circuits. Complete flexibility of logical function is achieved through the wiring interconnecting the sockets, and the only additional requirements are the supply of clock pulses and of d-c power.
