IBM 7151 Console Control Unit for 7090. The IBM 7090 is a second-generation transistorized version of the earlier IBM 709 vacuum tube mainframe computer that was designed for "large-scale scientific and technological applications".
This feature added five operation codes and was needed as a buffer for tape and disk I/O. The 60 words could also be used by programs to speed up inner loops and table lookups. Three four-digit index registers at addresses 8005 to 8007; drum addresses were indexed by adding 2000, 4000 or 6000 to them, core addresses were indexed by adding 0200 ...
By 1957, EDVAC was running over 20 hours a day with error-free run time averaging 8 hours. EDVAC received a number of upgrades including punch-card I/O in 1954, extra memory in slower magnetic drum form in 1955, and a floating-point arithmetic unit in 1958. EDVAC ran until 1962 [11] when it was replaced by BRLESC.
The die from an Intel 8742, an 8-bit microcontroller that includes a CPU running at 12 MHz, RAM, EPROM, and I/O While the earliest microprocessor ICs literally contained only the processor, i.e. the central processing unit, of a computer, their progressive development naturally led to chips containing most or all of the internal electronic ...
A human computer, with microscope and calculator, 1952. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary, the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait: "I haue [] read the truest computer of Times, and the best ...
Models prior to 2020 uses this convention: The first number after the letter T is the screen size in inch without the number 1 (i.e. T5xx for 15" models). The second number is the generation. Intel-based models have the last number being 0 or 1 while AMD-based models have the number being 5 or 6.
Wishbone adapts well to common topologies such as point-to-point, many-to-many (i.e. the classic bus system), hierarchical, or even switched fabrics such as crossbar switches. In the more exotic topologies, Wishbone requires a bus controller or arbiter, but devices still maintain the same interface.
The Subaru Outback is an automotive nameplate used by the Japanese automaker Subaru for two different SUV-themed vehicles: a Legacy-derived crossover station wagon, the Outback (1994–present, also sold as Legacy Outback (Japanese: スバル・レガシィアウトバック, Hepburn: Subaru Regashi Autobakku) in some markets), and an Impreza-derived off-road themed hatchback, the Outback ...
