Xerox Dolphin

Xerox Dolphin is a computer workstation developed by Xerox in the 1970s, known for its innovative design and technological advancements, which influenced the development of later workstations by Apple, IBM, and Microsoft. The Xerox Dolphin was part of the Xerox Alto series, a line of computers that also included the Xerox Star and Xerox Dandelion, designed by Butler Lampson, Chuck Thacker, and Alan Kay. The Xerox Dolphin was used by researchers at Xerox PARC (Palo Alto Research Center), Stanford University, and MIT (Massachusetts Institute of Technology), including notable computer scientists like Douglas Engelbart and Vint Cerf. The computer's design was also influenced by the work of John McCarthy and Marvin Minsky at MIT AI Lab.

Introduction

The Xerox Dolphin was a significant innovation in the field of computer science, building on the work of earlier computers like the Xerox Alto and DEC PDP-11. It was designed to be a powerful and flexible workstation, capable of running a variety of applications, including Smalltalk, a programming language developed by Alan Kay and his team at Xerox PARC. The Xerox Dolphin was also used by researchers at Carnegie Mellon University and University of California, Berkeley, including Raj Reddy and David Patterson. The computer's hardware was designed by Chuck Thacker and Butler Lampson, who also worked on the Xerox Star and Xerox Dandelion.

History

The development of the Xerox Dolphin began in the early 1970s, as part of the Xerox Alto project, which aimed to create a series of innovative computer workstations. The Xerox Dolphin was released in 1979, and was used by researchers at Xerox PARC and other institutions, including Stanford University and MIT. The computer was also used by the United States Department of Defense and NASA (National Aeronautics and Space Administration), for applications such as computer-aided design and simulation. The Xerox Dolphin was also influenced by the work of John von Neumann and Alan Turing on the development of the EDVAC and ACE computers.

Design_and_Development

The Xerox Dolphin was designed to be a high-performance workstation, with a MOS Technology 6502 microprocessor and up to 256 KB of RAM. The computer also featured a bitmapped display and a mouse input device, which were innovative features at the time. The Xerox Dolphin was developed by a team of researchers at Xerox PARC, including Butler Lampson, Chuck Thacker, and Alan Kay, who also worked on the Xerox Star and Xerox Dandelion. The computer's design was influenced by the work of Douglas Engelbart and his team at Stanford Research Institute (SRI), who developed the oN-Line System (NLS). The Xerox Dolphin was also influenced by the work of Ken Thompson and Dennis Ritchie on the development of the Unix operating system.
