Engineering multistage diode logic circuits

THIS article presents the method used for engineering the multistage diode logical function circuitry for a special-purpose computer employing exclusively semiconductor devices. Although the techniques used have been largely influenced by the devices available or being developed for the rest of the system, it is felt that these devices are typical of the general type of transistor device which may be expected in the near future. The methods to be described are partly graphical: no assumption of constant forward diode resistance is made. In this way, they differ from analysis methods based on Thévenin´s theorem.
