Xerox PARC (Xerox Palo Alto Research Center) designer Alan Kay intended the Notetaker to be a portable universal learning appliance. Built by Doug Fairbairn, the computer, weighing 48 pounds, featured an internal monitor and floppy disk drive as well as a mouse. Like the Xerox Alto, the Notetaker used a version of the Smalltalk-78 operating environment.
The Notetaker’s design set the trend for many later “luggable” computers such as the Osborne 1 and the Compaq Portable. Xerox built about ten Notetaker prototypes and never offered the machine for sale as a product.
