(1953–1966), informally known as 3C, was a pioneering [minicomputer](/source/minicomputer) company known for its DDP-series (Digital Data Processor) computers, notably:{{efn|name=Sequence}} *[DDP-24](/source/DDP-24) 24-bit (1963) *DDP-224 24-bit (1965) *[DDP-116](/source/DDP-116) 16-bit (1965) *DDP-124 24-bit (1966) using monolithic ICs It was founded in 1953 by Dr. [Louis Fein](/source/Louis_Fein), the physicist who had earlier designed the Raytheon [RAYDAC](/source/RAYDAC) computer.''Background,'' Vol. 7, No. 2 (Aug., 1963), pp. 109–110; published by: Blackwell Publishing on behalf of The International Studies Association The company moved to [Framingham, Massachusetts](/source/Framingham%2C_Massachusetts), in 1959. Prior to the introduction of the DDP-series it developed a series of digital logical modules, initially based on vacuum tubes. In 1966, it was sold to [Honeywell, Inc.](/source/Honeywell) As the Computer Controls division of Honeywell, it introduced further [DDP-series computers](/source/Honeywell_316), and was a $100,000,000 business until 1970 when Honeywell purchased GE's computer division and discontinued development of the DDP line.{{cite web|url=http://www.series16.adrianwise.co.uk/history/ccc.html|title=Computer Control Company|publisher=Adrian Wise|author=Adrian Wise|accessdate=2008-06-09}} In a 1970 essay, [Murray Bookchin](/source/Murray_Bookchin) used the DDP-124 as his example of computer progress: {{cquote|In 1945, [J. Presper Eckert](/source/J._Presper_Eckert), Jr. and [John W. Mauchly](/source/John_W._Mauchly) of the University of Pennsylvania unveiled the [ENIAC](/source/ENIAC) ... it weighed more than thirty tons, contained 18,800 vacuum tubes with half a million connections (the connections took Eckert and Mauchly two and a half years to solder. It often broke down or behaved erratically... Some twenty years later, the Computer Control Company of Framingham, Massachusetts offered the DDP-124 for sale. The DDP-124 is a small, compact computer that resembles a bedside AM-radio receiver. The entire ensemble, together with a typewriter and memory unit, occupies a typical office desk. The DDP-124 performs over 285,000 computations a second. It has a true stored-program memory that can be expanded to retain nearly 33,000 words... Its pulses cycle at 1.75 billion[sic] per second. The DDP-124 does not require any air-conditioning unit. It is completely reliable, and it creates very few maintenance problems.... The difference between ENIAC and DDP-124 is one of degree rather than kind.Bookchin, Murray, (1970), "Toward a Liberatory Technology," in ''Post-Scarcity Anarchism,'' AK Press, 2004, {{ISBN|1-904859-06-2}}; pp. 57–8}} One of the oddest of the DDP series was the DDP 19—of which only three were built on custom order for the U.S. Weather service. Its architecture was based on a 19-bit word structure consisting of six octal bytes plus a sign bit, which in arithmetic operations could create the unusual value of ["negative zero"](/source/Signed_zero). One of these machines was donated by the government to the Milwaukee Area Technical College in 1972, which included a drum-based line printer and dual Ampex magnetic tape drives. It was used for a limited number of students as an "extra credit project device" for the next 2–3 years, after which it was scrapped to make space for newer equipment. The fate of the other two units is unknown. ==Notes== {{notelist|refs= {{efn|name=Sequence|One of the developers of the DDP-124, [William Poduska](/source/William_Poduska), who later on became one of the founders of [Prime Computer](/source/Prime_Computer), said in a 2002 interview that the 124 came after the 224, which came after the 24.}} }} ==References== {{cite web |url=http://www.ddp116.org/products/ddp124/ddp124.pdf |title=DDP-124 Microcircuit General Purpose Digital Computer}} Confirms the 24, 224, 124 sequence [http://ed-thelen.org/comp-hist/AdamsReport1967Q4-1968Q1.pdf Adams Report 1967, PDF] {{cite web |url=https://archive.org/details/bitsavers_computersA_7721632/page/n43 |title=DDP-24 Announced by Computer Controls |date=July 1965 |website=Archive.org |publisher=Computers and Automation |access-date=April 1, 2019}} {{Cite book |url=https://books.google.com/books?id=Y0OeBQAAQBAJ&q=%22DDP-224%22%20first%20installed&pg=PA20 |title=The European Computer Users Handbook 1968/69 |publisher=Pergamon Press |series=Computer Data Series |edition=Sixth |last=Zhou |first=Yong |date=1968 |others=Computer Consultants Limited |isbn=9781483146690 |pages=111.20 |lccn=63-25287 |language=en}} ==External links== *[http://purl.umn.edu/107284 Oral history interview with Louis Fein] at [Charles Babbage Institute](/source/Charles_Babbage_Institute), University of Minnesota, Minneapolis.
