ABSTRACT:
A graphical logic computer is formed by apertured parameter slides that are moved back and forth in an envelope between an apertured cover member and a back panel. The cover member has an event network with paths that branch from and connect event windows formed by the apertures in the cover member. Event indicators are disposed on the back panel in position to be observed through the event windows provided none of the parameter slides obstructs its view. The parameter slides have logic windows, and the position of each parameter slide with a logic window or solid portion aligned with an event window corresponds to a logical input, the combination of two or more such imputs providing a logical output. For each combination of slide positions, a single path is observed through the event network to a logically determined result.
