USB interface created for Engelbart’s 1968 keyset, part of his “Mother of All Demos.” Engelbart revolutionized computing with innovations like the mouse and GUI, showcasing them at a conference but the keyset was less successful. The author created a modern USB interface for the keyset, detailing technical aspects and challenges. The term “Mother of All Demos” originated from a 1991 Intel presentation, later retroactively applied to Engelbart’s demo. Engelbart’s work faced long-term neglect, but eventually gained recognition, influencing future technology.
