The first mass-produced computer with floating-point arithmetic hardware for scientific use. Used magnetic-core memory and 36-bit binary words. First commercial vacuum-tube computer in Germany built by Heinz Nixdorf 's Labor für Impulstechnik. Mostly compatible with the IBM 702, for business use.
CSIRAC ( / ˈsaɪræk /; Commonwealth Scientific and Industrial Research Automatic Computer ), originally known as CSIR Mk 1, was Australia 's first digital computer, and the fifth stored program computer in the world. [1] It is the oldest surviving first-generation electronic computer [2] (the Zuse Z4 at the Deutsches Museum is older, but was ...
An open PDP-8/E with its logic modules behind the front panel and one dual TU56 DECtape drive at the top. A "Straight-8" running at the Stuttgart Computer Museum. The earliest PDP-8 model, informally known as a "Straight-8", was introduced on 22 March 1965 priced at $18,500 [2] (equivalent to about $178,900 in 2023 [3] ).
ESA/390. z/Architecture. v. t. e. The IBM 700/7000 series is a series of large-scale ( mainframe) computer systems that were made by IBM through the 1950s and early 1960s. The series includes several different, incompatible processor architectures. The 700s use vacuum-tube logic and were made obsolete by the introduction of the transistorized ...
The IBM Personal Computer (model 5150, commonly known as the IBM PC) is the first microcomputer released in the IBM PC model line and the basis for the IBM PC compatible de facto standard. Released on August 12, 1981, it was created by a team of engineers and designers directed by William C. Lowe and Philip Don Estridge in Boca Raton, Florida .
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations ( computation ). Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. The term computer system may refer to a nominally ...
Functionally, EDVAC was a binary serial computer with automatic addition, subtraction, multiplication, programmed division and automatic checking with an ultrasonic serial memory [3] having a capacity of 1,024 44-bit words. EDVAC's average addition time was 864 microseconds and its average multiplication time was 2,900 microseconds.
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 ...
