Xerox NoteTaker

from Wikipedia, the free encyclopedia

The Xerox NoteTaker was one of the first early portable computers. The calculator was developed at Xerox PARC in Palo Alto in 1976. Although the computer never went into series production and only about ten prototypes of the computer were produced, the model had a strong influence on the Osborne 1 and Compaq portable computers that were later released .

The NoteTaker was implemented by a team led by the developers Adele Goldberg , Douglas Fairbairn and Larry Tesler . The basic concept of the computer was based heavily on Alan Kay's Dynabook concept . While the Dynabook was a concept for a portable computer that could not be implemented with the existing technology at the time, the NoteTaker was intended to demonstrate what could realistically be implemented with the existing technology (24 kg) at the time.

The computer contained very high-performance technology for the time: a monochrome monitor built into the housing , a floppy disk drive and a mouse . The computer was equipped with 256 kB RAM , which was a very large memory at the time. An Intel 8086 clocked at 1 MHz was used as the main processor , two more of these chips were responsible for the graphics and input / output (network, etc.). The Xerox NoteTaker used a version of the Smalltalk operating system developed for the Xerox Alto computer.
