Alan Turing
<person> Alan M. Turing, 1912-06-22/3? - 1954-06-07. A
British mathematician, inventor of the Turing Machine.
Turing also proposed the Turing test. Turing's work was
fundamental in the theoretical foundations of computer
science.
Turing was a student and fellow of King's College Cambridge
and was a graduate student at Princeton University from 1936
to 1938. While at Princeton Turing published "On Computable
Numbers", a paper in which he conceived an abstract machine,
now called a Turing Machine.
Turing returned to England in 1938 and during World War II, he
worked in the British Foreign Office. He masterminded
operations at Bletchley Park, UK which were highly
successful in cracking the Nazis "Enigma" codes during World
War II. Some of his early advances in computer design were
inspired by the need to perform many repetitive symbolic
manipulations quickly. Before the building of the Colossus
computer this work was done by a roomful of women.
In 1945 he joined the National Physical Laboratory in London
and worked on the design and construction of a large computer,
named Automatic Computing Engine (ACE). In 1949 Turing
became deputy director of the Computing Laboratory at
Manchester where the Manchester Automatic Digital Machine,
the worlds largest memory computer, was being built.
He also worked on theories of artificial intelligence, and
on the application of mathematical theory to biological forms.
In 1952 he published the first part of his theoretical study
of morphogenesis, the development of pattern and form in
living organisms.
Turing was gay, and died rather young under mysterious
circumstances. He was arrested for violation of British
homosexuality statutes in 1952. He died of potassium cyanide
poisoning while conducting electrolysis experiments. An
inquest concluded that it was self-administered but it is now
thought by some to have been an accident.
There is an excellent biography of Turing by Andrew Hodges,
subtitled "The Enigma of Intelligence" and a play based on it
called "Breaking the Code". There was also a popular summary
of his work in Douglas Hofstadter's book "Gödel, Escher,
Bach".

FC-PGA2 Tualatin Adapter for Socket 370 FC-PGA MBBFC-PGA2 Tualatin Adapter for Socket 370 FC-PGA MBB ** Socket 370 to Tualatin CPU Adapter **With this adapter, your customers can now use new Intel Pentium III and Celeron processors with Tualatin cores in their Socket 370 motherboards that do not have native support for these processors. This is packaged in a retail box.General Features: - Adapts Socket 370 motherboards made for FC-PGA processors for use with FC-PGA2 (Tualatin) processors- Also adapts Socket 370 motherboards made for PPGA processors for use with FC-PGA (Coppermine) processors- Adds approximately 3/8 inch to the height of the processor/cooler combination Retail Package Includes: - Socket 370 Adapter with three jumpers - Instructions printed on back of boxNotes:- The box and instructions have some grammatical and spelling errors, but this device worked well in our in-house tests. We tested it with a Biostar M6VCF motherboard using both a Celeron 1200 and a Pentium III 1133 (both Tualatin processors). In the case of the Celeron 1200, the BIOS of the M6VCF saw it as a Pentium III 305, but Sandra 2002 saw it as a Celeron 1200, and it ran without problems. - This adapter will not increase the available Front Side Bus (FSB) speed of the motherboard. Your motherboard must support the FSB of your desired processor for its full speed potential to be used. - Additional jumpers may be needed for proper set up Compatibility/Requirements/Disclosures:** Requirements *** Socket 370 Motherboard* Pentium III or Celeron processor with Tualatin core** Disclosures *** May not work with all motherboards.
