Scripsit
Scripsit is a word processing application written for the Radio Shack TRS-80 line of computers. Versions were available for most if not all computers sold under the TRS-80 name, including the Color Computer and several pocket computer designs, as well as the Tandy version of the Xenix operating system. Tandy Corp. also produced a version running under MS-DOS for its line of PC compatible computers (Tandy 1000 and successors). Some of the 8-bit versions are tape-based and have no ability to read or write to disk. The word scripsit is a Latin verb equivalent to the English "wrote". It was often used as an inscription indicating the identity of the person who wrote something. Functionality Scripsit is a rudimentary word processor. It has basic text entry and margin controls, as well as word wrap. Many versions tied to specific platforms were available, and each version had its own set of features. Most versions supported variable width fonts, specifically for daisy-wheel printer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TRS-80
The TRS-80 Micro Computer System (TRS-80, later renamed the Model I to distinguish it from successors) is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of ''Tandy Radio Shack, Z80 icroprocessor'. It is one of the earliest mass-produced and mass-marketed retail home computers. The TRS-80 has a full-stroke QWERTY keyboard, the Zilog Z80 processor, 4 KB dynamic random-access memory (DRAM) standard memory, small size and desk area, floating-point Level I BASIC language interpreter in read-only memory (ROM), 64-character per line video monitor, and a starting price of US$600 (equivalent to US$ in ). A cassette tape drive for program storage was included in the original package. While the software environment was stable, the cassette load/save process combined with keyboard bounce issues and a troublesome Expansion Interface contributed to the Model I's reputation as not well-suited to serious ...

TRS-80 Model II
The TRS-80 Model II is a computer system launched by Tandy in October 1979, and targeted at the small-business market. It is not an upgrade of the original TRS-80 Model I, but a new system. The Model II was succeeded by the compatible TRS-80 Model 12, Model 16, Model 16B, and the Tandy 6000. Model II Background Tandy was surprised at the strong demand for the TRS-80 Model I from business purchasers. The computer was too limited for such use, so the company began development on the Model II in late 1978. It was announced in May 1979, deliveries began in October, and only Tandy-owned Radio Shack stores sold the computer. Tandy advertised the Model II as "a business computer — not a hobby, 'home' or personal computer". It claimed that the computer was "ideal for a small business, and also 'just right' for many time-consuming jobs within larger businesses", including those with mainframes or minicomputers. The base single disk version was , and a four disk version was . Hardware A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Pencil
Electric Pencil, released in December 1976 by Michael Shrayer, was the first word processor for home computers. History In 1975, Michael Shrayer had moved to California after 20 years as a New York filmmaker. Enjoying assembling electronic kits, he purchased and assembled a MITS Altair 8800 computer, then modified a public domain assembler program for the Processor Technology Sol-20. Fellow computer hobbyists wanted to buy Shrayer's ESP-1 software, giving him an unexpected and lucrative new business. Having never heard of a "word processor", Shrayer nonetheless believed that he should be able to use his computer, instead of a typewriter, to write documentation for his program, and thus wrote another program – the first word processor for a microcomputer – with which to do so. Electric Pencil for the Altair appeared in December 1976, and the version for the Sol-20 became especially popular. As no large network of computer stores existed, Shrayer formed Michael Shrayer Softwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandy Corporation
Tandy Corporation was an American family-owned leather goods company based in Fort Worth, Texas, United States. Tandy Leather was founded in 1919 as a leather supply store. By the end of the 1950s, under the tutelage of then-CEO Charles Tandy, the company expanded into the hobby market, making leather moccasins and coin purses, making huge sales among Scouts, leading to a fast growth in sales. Entering the 1960s, aiming to broaden the company horizon, Charles Tandy acquired a number of craft retail companies, including RadioShack in 1963, then an almost bankrupt chain of electronics stores in Boston. In the 1980s, now led by John Roach as CEO, the corporation started to invest into the personal computer market, being one of the pioneers in the personal computer race, being lauded by the magazine ''Financial World'' as "the driving force at the front-running company in the red-hot personal computer race." In 2000, the Tandy Corporation name was dropped and the entity became t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM PC
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 Don Estridge in Boca Raton, Florida. The machine was based on open architecture and third-party peripherals. Over time, expansion cards and software technology increased to support it. The PC had a substantial influence on the personal computer market. The specifications of the IBM PC became one of the most popular computer design standards in the world. The only significant competition it faced from a non-compatible platform throughout the 1980s was from the Apple Macintosh product line. The majority of modern personal computers are distant descendants of the IBM PC. History Prior to the 1980s, IBM had largely been known as a provider of business computer systems. As the 1980s opened, their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spell Checking
In software, a spell checker (or spelling checker or spell check) is a software feature that checks for misspellings in a text file, text. Spell-checking features are often embedded in software or services, such as a word processor, email client, electronic dictionary, or search engine. Design A basic spell checker carries out the following processes: * It scans the text and extracts the words contained in it. * It then compares each word with a known list of correctly spelled words (i.e. a dictionary). This might contain just a list of words, or it might also contain additional information, such as hyphenation points or lexical and grammatical attributes. * An additional step is a language-dependent algorithm for handling morphology (linguistics), morphology. Even for a lightly inflected language like English language, English, the spell checker will need to consider different forms of the same word, such as plurals, verbal forms, contraction (grammar), contractions, and possessi ...

Who Dares Wins (film)
''Who Dares Wins'' is a 1982 British political thriller film directed by Ian Sharp and starring Lewis Collins, Judy Davis, Richard Widmark, Tony Doyle and Edward Woodward The title is the motto of the British Army’s elite Special Air Service (SAS). The plot is based largely on the Iranian Embassy siege of 1980 in London, when a team from the SAS made a sudden assault on the building to rescue those being held hostage inside. As producer, Euan Lloyd was inspired to make the film by visiting the scene during the siege and watching live coverage of it on television, moving quickly to prevent someone else developing the same idea. An initial synopsis was created by George Markstein. This was then turned into a novel by James Follett, as ''The Tiptoe Boys'', in 30 days. Meanwhile, chapter-by-chapter as the novel was completed, it was posted to Reginald Rose in Los Angeles, who wrote the final screenplay. The film was released in the United States as ''The Final Option''. Plot A de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Virtual Memory
In computing, virtual memory, or virtual storage is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" which "creates the illusion to users of a very large (main) memory". The computer's operating system, using a combination of hardware and software, maps memory addresses used by a program, called '' virtual addresses'', into ''physical addresses'' in computer memory. Main storage, as seen by a process or task, appears as a contiguous address space or collection of contiguous segments. The operating system manages virtual address spaces and the assignment of real memory to virtual memory. Address translation hardware in the CPU, often referred to as a memory management unit (MMU), automatically translates virtual addresses to physical addresses. Software within the operating system may extend these capabilities, utilizing, e.g., disk storage, to provide a virtual address space that ca ...
