Colossus was a set of computers developed by British codebreakers in the years 1943–1945 [ 1] to help in the cryptanalysis of the Lorenz cipher. Colossus used thermionic valves (vacuum tubes) to perform Boolean and counting operations. Colossus is thus regarded [ 2] as the world's first programmable, electronic, digital computer, although it ...

Decimal, via standard IBM 80-column punched cards. Mass. 700 pounds (320 kg) The Atanasoff–Berry computer ( ABC) was the first automatic electronic digital computer. [1] Limited by the technology of the day, and execution, the device has remained somewhat obscure. The ABC's priority is debated among historians of computer technology, because ...
