If you include arithmatic mechanisms, then the first would be the abacus from circa 2700 BC. The Antikythera mechanism was an analog mechanical device from circa 200 BC and was used to predict astronomical positions and eclipses. If you mean general purpose mechanical computer, that would be Charles Babbage's Difference Engine, designed in the 1820s. The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer, though it wasn't programmable and was more of an arithmetic logic unit, conceived in 1937. The Z3 was an electromechanical programmable, fully automatic digital computer circa 1941. The British Colossus was a set of computers and was the first programmable, electronic, digital computer, although it was programmed by switches and plugs. The ENIAC was similar to the Colossus and it was Turing-complete though still programmed by patch cables and switches. The Manchester Baby, circa 1948, was the first electronic stored-program computer designed as a testbed for random access memory. It was the first working machine to contain all the elements essential to a modern electronic digital computer. So if you define "computer" as fully electronic, programmable, digital, Turing-complete and containing electronic memory, the first was the Manchester Baby. -- penninojim@yahoo.com
