Optical Data Memories for Minicomputers

This thesis describes the electronics of an interface constructed to allow communication between an optical disk memory storage medium and a minicomputer. The interface is primarily intended to allow data recorded in a discreet level form to be entered into a minicomputer as digital information. The experimental system consists of a PDP8/a minicomputer with 8K words of core memory, an interprocessor buffer, a data break board, and a controller board together with external electronics which simulate the signals from the mass memory
