Symbolics was a spinoff from the MIT AI Lab, one of two companies to be founded by AI Lab staffers and associated hackers for the purpose of manufacturing Lisp machines.

The development of Macsyma continued at Symbolics despite the fact that it was seen as a diversion from the sales of Lisp machines, which Symbolics considered to be their main business despite the fact that Macsyma sales and the leveraged sales of Lisp Machines reached 10 % of overall sales at Symbolics within two years.

Symbolics hired most of the lab hackers, and a schism was created between the two groups of hackers, to the point where some would not even talk to each other.

The AI Lab led to the invention of Lisp machines and their attempted commercialization by two companies in the 1980s: Symbolics and Lisp Machines Inc.

So for two years at the MIT AI Lab, from 1982 to the end of 1983, Stallman singlehandedly duplicated the efforts of the Symbolics programmers, in order to prevent them from gaining a monopoly on the lab's computers.

Several companies were building and selling Lisp Machines in the 1980s: Symbolics ( 3600, 3640, XL1200, MacIvory and other models ), Lisp Machines Incorporated ( LMI Lambda ), Texas Instruments ( Explorer and MicroExplorer ) and Xerox ( InterLisp-D workstations ).

Several companies developed and sold applications for Symbolics Genera.

Lisp Machines were commercialized beginning 1980 by companies like Symbolics, Lisp Machines, Texas Instruments ( the TI Explorer ) and Xerox ( the Interlisp-D workstations ).

Many of the newly hired American Lisp staff had previously worked for Lucid Inc. and Symbolics, other Lisp companies which had previously failed.

While both companies delivered proprietary software, Richard Stallman believed that LMI, unlike Symbolics, had tried to avoid hurting the lab.

Both companies developed second-generation products based on the CADR: the Symbolics 3600 and the LMI-LAMBDA ( of which LMI managed to sell around 200 ).

Symbolics, Inc. was a computer manufacturer headquartered in Cambridge, Massachusetts, and later in Concord, Massachusetts, with manufacturing facilities in Chatsworth, California ( a suburban section of Los Angeles ).

The first commercial Internet domain name, in the TLD. com, was registered on 15 March 1985 in the name symbolics. com by Symbolics Inc., a computer systems firm in Cambridge, Massachusetts.

Symbolics, a maker of the Lisp machines, licensed the MIT Chaosnet hardware and software implementation from the CADR computer design.

After working for Hewlett Packard Research Labs in Palo Alto and Symbolics, he became a founder of ICAD, Inc. Greenspun returned to MIT to study electrical engineering and computer science, eventually receiving a Ph. D.

He founded Lisp Machines, Inc. ( which later became Gigamos Systems ), according to his vision of an ideal hacker-friendly computer company, as opposed to the more commercial ideals of Symbolics.

The other was Lisp Machines, Inc., although Symbolics attracted most of the hackers, and more funding.

At that point, Symbolics began using their own copy of the software, located on their company servers — while Stallman says that Symbolics did that to prevent its Lisp improvements from flowing to Lisp Machines, Inc. From that base, Symbolics made extensive improvements to every part of the software, and continued to deliver almost all the source code to their customers ( including MIT ).

In early 1982, Macsyma was licensed by MIT to Arthur D. Little, Inc., which became the broker for Macsyma and soon licensed Macsyma to Symbolics in late 1982.

Macsyma, Inc., was founded in 1992 by Russell Noftsker ( chairman, who had co-founded Symbolics ) and Richard Petti ( president, who had turned around Macsyma for a time at Symbolics ) by raising funds and purchasing the rights to Macsyma from the ailing Symbolics.

Noftsker formed Symbolics with Robert Adams and a number of AI Lab hackers, taking on the role of president and chairman ; Greenblatt would eventually start Lisp Machines Inc.

They went on to start Symbolics Inc.

When Symbolics Inc. bought the commercial rights to Macsyma from MIT to sell along with its Lisp Machines, it eventually was compelled to sell Macsyma also on DEC VAX and Sun Microsystems computers, paying royalties to the University of California for the use of Franz Lisp.
