Scarce original circa 1982 three-button 'Mark II' Hawley X063X roller mouse (Ser. No. 08368) developed for Xerox PARC by Bill English (co-inventor of the original mouse) and Jack Hawley, which was personally gifted by computer visionary Douglas Engelbart to his friend and colleague, Bill Daul, who was a member of Engelbart's pioneering research team at SRI. The rectangular mouse, 2″ x 3.25″ x 1″, features three black buttons to the top, and a clear product label from The Mouse House (Berkeley, California) to the underside. The mouse retains its original wire with a serial port connection. In fine condition, with missing coating to the wire.
Computer visionary Douglas Engelbart is remembered for founding the field of human–computer interaction and for his development of the computer mouse. His original patent for an 'X-Y Position Indicator for a Display System' was filed in 1967 and introduced at the Augmentation Research Center (ARC) of Stanford Research Institute (SRI) in Menlo Park, California, the next year, in 'The Mother of All Demos.'
