Abstract
Abstract A method of, and device for, the digital simulation of digital computer configurations, in which the various computer modules of a computer configuration to be simulated, are replaced by hardware digital simulation modules which can be placed on a panel, and which are connected in accordance with the configuration. During the simulation, the actual speeds of the simulated computer modules are represented by adjustable clock pulse signals which are applied to the simulation modules. Display modules signal the conditions occurring in and on the outputs of the simulation modules.
