Scientific Data Systems, or SDS, was an American computer company founded in September 1961 by Max Palevsky and Robert Beck, veterans of Packard Bell and Bendix, along with eleven other computer scientists.
 SDS was an early adopter of integrated circuits in computer design and the first to employ silicon transistors.
 The company concentrated on larger scientific workload focused machines and sold many machines to NASA during the Space Race.
 Most machines were both fast and relatively low priced.
 The company was sold to Xerox in 1969, but dwindling sales due to the oil crisis of 1973–74 caused Xerox to close the division in 1975 at a loss of hundreds of millions of dollars.
 During the Xerox years the company was officially Xerox Data Systems, or XDS.
Acorn Computers Ltd. was a British computer company established in Cambridge, England, in 1978.
 The company produced a number of computers which were especially popular in the UK, including the Acorn Electron and the Acorn Archimedes.
 Acorn's BBC Micro computer dominated the UK educational computer market during the 1980s.
 It is more known for its BBC Micro model B computer than for its other products.
Alpha Microsystems is a computer company founded in 1977 by John French, Dick Wilcox and Bob Hitchcock.
 The first Alpha Micro computer was the S-100 AM-100, based upon the WD16 microprocessor chipset from Western Digital.
 Later computers starting with the AM-100/L and the AM-1000 were based on the Motorola 68000 and succeeding processors, though Alpha Micro swapped several addressing lines to create byte-ordering compatibility with their earlier processor.
The Cray MTA-2 is a shared-memory MIMD computer marketed by Cray Inc. It is an unusual design based on the Tera computer designed by Tera Computer Company.
 The original Tera computer (also known as the "MTA") turned out to be nearly unmanufacturable due to its aggressive packaging and circuit technology.
 The MTA-2 was an attempt to correct these problems while maintaining essentially the same processor architecture respun in one silicon ASIC, down from some 26 gallium arsenide ASICs in the original MTA; and while advancing the network design from a 4-D torus topology to a more scalable Cayley graph topology.
 The name "Cray" was added to the second version after Tera Computer Company bought the remains of the Cray Research division of Silicon Graphics in 2000 and renamed itself Cray Inc.
People's Computer Company (PCC) was an organization, a newsletter (the People's Computer Company Newsletter) and, later, a quasiperiodical called the Dragonsmoke.
 PCC was founded and produced by Dennis Allison, Bob Albrecht and George Firedrake in Menlo Park, California in the early 1970s.
Processor Technology Corporation was a personal computer company founded in April 1975 by Gary Ingram and Bob Marsh in Berkeley, California.
 Their first product was a 4K byte RAM board that was compatible with the MITS Altair 8800 computer but more reliable than the MITS board.
 This was followed by a series of memory and I/O boards including a video display module.
 Popular Electronics magazine wanted a feature article on an intelligent computer terminal and Technical Editor Les Solomon asked Marsh and Lee Felsenstein to design one.
 It was featured on the July 1976 cover and became the Sol-20 Personal Computer.
 The first units were shipped in December 1976 and the Sol-20 was a very successful product.
 The company failed to develop next generation products and ceased operations in May 1979.
Wang Laboratories was a computer company founded in 1951, by An Wang and G. Y. Chu.
 The company was successively headquartered in Cambridge, Massachusetts (1954–1963), Tewksbury, Massachusetts (1963–1976), and finally in Lowell, Massachusetts (1976–1997).
 At its peak in the 1980s, Wang Laboratories had annual revenues of $3 billion and employed over 33,000 people.
 It was one of the leading companies during the time of the Massachusetts Miracle.
Be Inc. was an American computer company founded in 1990, best known for the development and release of BeOS, and the BeBox personal computer.
 Be was founded by former Apple Computer executive Jean-Louis Gassée with capital from Seymour Cray.
Nixdorf Computer AG was a West German computer company founded by Heinz Nixdorf in 1952.
 Headquartered in Paderborn, Germany, it became the fourth largest computer company in Europe, and a worldwide specialist in banking and point-of-sale systems.
The Talking Propellerheads was a high technology satire/rock/comedy band performing from 1982 through 1996.
 The group was composed of employees of Data General Corporation.
 They were notable as the "corporate band" for Data General for over 14 years, playing at industry events and company functions.
 Their songs documented the fall of the minicomputer industry of the 1980s with their songs about Wang, DEC, Prime, IBM and other companies.
 Their songs reported on changes in the minicomputer industry such as An Wang's retirement ("they thought that Fred could run the company, but An said "Fred, you're not the man for me"), as well as documenting some of the players that formed the industry: Data General founders (Ed DeCastro and Herb Richman, in "Eddie and Herb", Tom West in "Stairway to Heaven", and Ken Olsen in "Dec Stinks").

Question: The Talking Propellerheads released songs about the decline of which computer company founded in 1951 and once based in Cambridge, MA?
Answer: Wang Laboratories
