Acorn Archimedes is a family of personal computers designed by Acorn Computers of Cambridge, England.The systems are based on Acorn's own ARM architecture processors and the proprietary operating systems Arthur and RISC OS.The first models were introduced in 1987, and systems in the Archimedes family were sold until the mid-1990s. ARM's RISC design, a 32 …

In 1994, Acorn Computers launched its Risc PC series of high-end desktop computers. The Risc PC (codenamed Medusa) was Acorn's next generation ARM-based RISC OS computer, which superseded the Acorn Archimedes. In 2005, the ARM Cortex-A8 was released, the first Cortex design to be adopted on a large scale for use in consumer devices.

Christopher Curry (born 28 January 1946 in Cambridge) is the co-founder of Acorn Computers, with Hermann Hauser and Andy Hopper.He became a millionaire as a result of Acorn's success. In his early career days, he worked at Pye, Royal Radar Establishment and W.R. Grace Laboratories.Then, in April 1966 he joined Sinclair Radionics where he worked for 13 years.

The home computers between 1977 and about 1995 were different from today's uniform and predictable machines. During this time it made economic sense for manufacturers to make microcomputers aimed at the home user. By simplifying the machines, and making use of household items such as television sets and cassette recorders instead of dedicated computer …

RISC OS / r ɪ s k. oʊ ˈ ɛ s / is a computer operating system originally designed by Acorn Computers Ltd in Cambridge, England.First released in 1987, it was designed to run on the ARM chipset, which Acorn had designed concurrently for use in its new line of Archimedes personal computers. RISC OS takes its name from the reduced instruction set computer (RISC) …

Sophie Mary Wilson CBE FRS FREng DistFBCS (born Roger Wilson; June 1957) is an English computer scientist, who helped design the BBC Micro and ARM architecture.. Wilson first designed a microcomputer during a break from studies at Selwyn College, Cambridge.She subsequently joined Acorn Computers and was instrumental in designing the BBC Micro, …

Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using digital computers. The numerical values that make up a character encoding are known as "code points" and collectively comprise a "code space", a "code page", or a "character map".

Geschichte Die Vorläufer des modernen Computers. Die moderne Computertechnologie, wie wir sie heute kennen, entwickelte sich im Vergleich zu anderen Elektrogeräten der Neuzeit sehr schnell.Die Geschichte der Entwicklung des Computers an sich jedoch reicht zurück bis in die Antike und umfasst deutlich mehr, als nur die modernen Computertechnologien oder …

This article lists software and hardware that emulates computing platforms.. The host in this article is the system running the emulator, and the guest is the system being emulated.. The list is organized by guest operating system (the system being emulated), grouped by word length.Each section contains a list of emulators capable of emulating the specified guest, details of the …

Acorn Computers' first widely successful design was the BBC Micro, introduced in December 1981.This was a relatively conventional machine based on the MOS Technology 6502 CPU but ran at roughly double the performance of competing designs like the Apple II due to its use of faster dynamic random-access memory (DRAM). Typical DRAM of the era ran at about 2 MHz; …

May 06, 2021 · Cut the acorn squash into wedges. Use a sturdy serrated kitchen knife to cut the squash from end to end. Remove the strings and seeds, then cut each half into 1-inch (2.5-cm) slices.

A transistor is a semiconductor device with at least three terminals for connection to an electric circuit.In the common case, the third terminal controls the flow of current between the other two terminals. This can be used for amplification, as in the case of a radio receiver, or for rapid switching, as in the case of digital circuits.The transistor replaced the vacuum-tube triode, also ...

For more than two decades, the floppy disk was the primary external writable storage device used. Most computing environments before the 1990s were non-networked, and floppy disks were the primary means to transfer data between computers, a method known informally as sneakernet.Unlike hard disks, floppy disks are handled and seen; even a novice user can …

A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. Single-board computers are commonly made as demonstration or development systems, for educational systems, or for use as embedded computer controllers.Many types of …
