The Manchester Mark 1 final specification is completed; this machine was notably in being the first computer to use the equivalent of base/index registers, a feature not entering common computer architecture until the second generation around 1955.
The MANIAC I (Mathematical Analyzer Numerical Integrator and Automatic Computer Model I) [1] [2] was an early computer built under the direction of Nicholas Metropolis at the Los Alamos Scientific Laboratory. It was based on the von Neumann architecture of the IAS, developed by John von Neumann. As with almost all computers of its era, it was a ...
A more interactive form of computer use developed commercially by the middle 1960s. In a time-sharing system, multiple teleprinter and display terminals let many people share the use of one mainframe computer processor, with the operating system assigning time slices to each user's jobs. This was common in business applications and in science ...
Second oldest surviving computer in the world. [16] RCA BIZMAC: 1956 6: RCA's first commercial computer, it contained 25,000 tubes. BESM-2 1957 >20 Built in the Soviet Union. General purpose computer in the BESM series. IBM 610: 1957 180: A small computer designed to be used by one person with limited experience. SEA CAB 3000: 1957 4
The CM-1 and CM-2 design teams were led by Tamiko Thiel. [10] The physical form of the CM-1, CM-2, and CM-200 chassis was a cube-of-cubes, referencing the machine's internal 12-dimensional hypercube network, with the red light-emitting diodes (LEDs), by default indicating the processor status, visible through the doors of each cube.
The clock signal period was 1 microsecond (equivalent to a clock speed of 1 MHz), but the program speed averaged below 1,000 instructions per second due the many clock cycles needed for each operation and slow access to serial memory. [12] The machine was programmed in pure machine code using an array of buttons and switches. Output consisted ...
A program is a set of instructions used to control the behavior of a machine. Examples of such programs include: The sequence of cards used by a Jacquard loom to produce a given pattern within weaved cloth. Invented in 1801, it used holes in punched cards to represent sewing loom arm movements in order to generate decorative patterns automatically.
The MCM/70 [1] is a pioneering microcomputer first built in 1973 in Toronto, Ontario, Canada [2] [3] and released the next year. This makes it one of the first microcomputers in the world, the second to be shipped in completed form, and the first portable computer.
