The computer was an early all-in-one, becoming available two years after the CP/M-based Osborne 1 and Kaypro II, in the same year as the MS-DOS-based (but not entirely IBM PC compatible) Dynalogic Hyperion, and a year before the Commodore SX-64. Its design was influenced by that of the Xerox NoteTaker, a prototype computer developed at Xerox PARC in 1976.
