The Computer History Museum’s collection tells the biographies of its items, including an early Memorex videotape from 1968 recently acquired. The tape’s story begins with Debra Dunlop’s email about a collection belonging to her father, Robert Dunlop, an industrial psychologist at IBM, RCA, and Xerox. After receiving the collection, a rare video recording was discovered detailing a forgotten IBM computing system demo. The recording was restored by George Blood LP, revealing a starkly different vision of computing than the well-known “Mother of All Demos” by Doug Engelbart. Dunlop’s Executive Terminal showcased advanced computing for hierarchical organizations, contrasting Engelbart’s collaborative vision. The released video restores a lost chapter in computing history.
