The Wisconsin Integrally Synchronized Computer (WISC) was an early digital computer designed and built at the University of Wisconsin–Madison. Operational in 1954, [1] it was the first digital computer in the state. Pioneering computer designer Gene Amdahl drafted the WISC's design as his PhD thesis. The computer was built over the period ...
A mechanical computer is a computer built from mechanical components such as levers and gears rather than electronic components. The most common examples are adding machines and mechanical counters, which use the turning of gears to increment output displays. More complex examples could carry out multiplication and division—Friden used a ...

The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable, fully automatic digital computer. [3] The Z3 was built with 2,600 relays, implementing a 22- bit word length that operated at a clock frequency of about 5–10 Hz. [1]
ENIAC ( / ˈɛniæk /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [3] [4] Other computers had some of these features, but ENIAC was the first to have them all.
A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. While the history of mechanical aids to computation goes back centuries, if not millennia, the history of vacuum tube computers is confined to the middle of the 20th century. Lee De Forest invented the triode in 1906.
Astronautics Corporation of America ( ACA) was established in 1959 and is a US supplier, designer, and manufacturer of avionics equipment to airlines, governments, commercial and defense aircraft manufacturers, and other avionics systems integrators. Products are used for air, sea, ground, missile and space applications.
