Red Ryder (software)
Red Ryder is a communications and terminal emulation software program released for the Apple Macintosh in 1984. Initially distributed as a shareware, the application offered rich features and configuration settings. Red Ryder was discontinued in 1989 and replaced by White Knight. History First released in 1984 for Macintosh computers, early versions of Red Ryder were written by Wat Buchanon as a Microsoft BASIC program with documentation included on the disk filled with humor aimed at Apple and programmers. After Wat Buchanon died, his friend Scott Watson entirely rewrote Red Ryder keeping the manual in a similar humorous style. Watson's releases were a standalone Macintosh applications programmed in C and the new author expanded features taking into account requests from Red Ryder users. The application was distributed as a shareware until version 9.4, starting with release 10.0 in 1987 Red Ryder became a commercial program. Red Ryder was discontinued in 1989 (10.3 being the ...

Classic Mac OS
Mac OS (originally System Software; retronym: Classic Mac OS) is the series of operating systems developed for the Macintosh family of personal computers by Apple Computer from 1984 to 2001, starting with System 1 and ending with Mac OS 9. The Macintosh operating system is credited with having popularized the graphical user interface concept. It was included with every Macintosh that was sold during the era in which it was developed, and many updates to the system software were done in conjunction with the introduction of new Macintosh systems. Apple released the Macintosh 128K, original Macintosh on January 24, 1984. The System 1, first version of the system software, which had no official name, was partially based on the Lisa OS, which Apple previously released for the Apple Lisa, Lisa computer in 1983. As part of an agreement allowing Xerox to buy Share (finance), shares in Apple at a favorable price, it also used concepts from the Xerox PARC Xerox Alto, Alto computer, which ...

VT100
The VT100 is a video terminal, introduced in August 1978 by Digital Equipment Corporation (DEC). It was one of the first terminals to support ANSI escape codes for cursor control and other tasks, and added a number of extended codes for special features like controlling the status lights on the keyboard. This led to rapid uptake of the ANSI standard, which became the de facto standard for hardware video terminals and later terminal emulators. The VT100 series, especially the VT102, was extremely successful in the market, and made DEC the leading terminal vendor at the time. The VT100 series was replaced by the VT200 series starting in 1983, which proved equally successful. Ultimately, over six million terminals in the VT series were sold, based largely on the success of the VT100. Description DEC's first video terminal was the VT05 (1970), succeeded by the VT50 (1974), and soon upgraded to the VT52 (1975). The VT52 featured a text display with 80 columns and 24 rows, bidirection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hayes Microcomputer Products
Hayes Microcomputer Products was a U.S.-based manufacturer of modems. The company is well known for the Smartmodem, which introduced a control language for operating the functions of the modem via the serial interface, in contrast to manual operation with front-panel switches. This ''smart modem'' approach dramatically simplified and automated operation. Today almost all modems use a variant of the Hayes command set. Hayes was a major brand in the modem market from the introduction of the original 300 bit/s Smartmodem in 1981. They remained a major vendor throughout the 1980s, periodically introducing models with higher throughput. Their competition through this period was primarily from two other high-end vendors, US Robotics and Telebit, while other companies mostly sold into niches or were strictly low-end offerings. In the early 1990s a number of greatly cost-reduced high-performance modems were released by competitors, notably the SupraFAXModem 14400, which eroded price point ...

MacTerminal
MacTerminal was the first telecommunications and terminal emulation application software program available for the classic Mac OS. MacTerminal enabled users to connect via modem or serial port to bulletin board systems and online services (e.g., The Source, CompuServe), and to other computers. MacTerminal was capable of emulating the DEC VT100 and other computer terminals. Apple Computer began retailing MacTerminal in July 1984 following the launch of the Macintosh 128K (the first Apple Macintosh) in January. Although MacTerminal was compatible with the original 128K model using Apple's optional 300 or 1200 bit/s external modem designed for the Apple II, MacTerminal was not available for general release at the 128K's launch date. Apple began bundling MacTerminal with later Macintosh models. When Apple Computer, Inc. spawned Claris in 1987 as its application software division, Claris continued development of most of Apple's major applications, but development of MacTerm ...

Computer Magazine
Computer magazines are about computers and related subjects, such as computer network, networking and the Internet. Most computer magazines offer (or offered) advice, some offer Programming language, programming Tutorial, tutorials, reviews of the latest technologies, and advertisements. History 1940s–1950s *''Mathematics of Computation'' established in 1943, articles about computers began to appear from 1946 (Volume 2, Number 15) to the end of 1954. Scientific journal. *''Digital Computer Newsletter'', (1949–1968), founded by Albert Eugene Smith. *''Computers and Automation'', (1951–1978), was arguably the first computer magazine. It began as ''Roster of Organizations in the Computing Machinery Field'' (1951–1952), and then ''The Computing Machinery Field'' (1952–1953). It was published by Edmund Berkeley. ''Computers and Automation'' held the first Computer Art Contest circa 1963 and maintained a bibliography on computer art starting in 1966. It also included a mont ...

Modem
A modulator-demodulator or modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by Modulation#Digital modulation methods, modulating one or more carrier wave signals to encode digital information, while the receiver Demodulation, demodulates the signal to recreate the original digital information. The goal is to produce a Signal (electronics), signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio. Early modems were devices that used audible sounds suitable for transmission over traditional telephone systems and leased lines. These generally operated at 110 or 300 bits per second (bit/s), and the connection between devices was normally manual, using an attached telephone handset. By the 1970s, higher speeds of 1,200 and 2,400 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macro (computer Science)
In computer programming, a macro (short for "macro instruction"; ) is a rule or pattern that specifies how a certain input should be mapped to a replacement output. Applying a macro to an input is known as macro expansion. The input and output may be a sequence of lexical tokens or characters, or a syntax tree. Character macros are supported in software applications to make it easy to invoke common command sequences. Token and tree macros are supported in some programming languages to enable code reuse or to extend the language, sometimes for domain-specific languages. Macros are used to make a sequence of computing instructions available to the programmer as a single program statement, making the programming task less tedious and less error-prone. (Thus, they are called "macros" because a "big" block of code can be expanded from a "small" sequence of characters.) Macros often allow positional or keyword parameters that dictate what the conditional assembler program generates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Procedural Programming
Procedural programming is a programming paradigm, derived from imperative programming, based on the concept of the ''procedure call''. Procedures (a type of routine or subroutine) simply contain a series of computational steps to be carried out. Any given procedure might be called at any point during a program's execution, including by other procedures or itself. The first major procedural programming languages appeared circa 1957–1964, including Fortran, ALGOL, COBOL, PL/I and BASIC. Pascal and C were published circa 1970–1972. Computer processors provide hardware support for procedural programming through a stack register and instructions for calling procedures and returning from them. Hardware support for other types of programming is possible, but no attempt was commercially successful (for example Lisp machines or Java processors). Procedures and modularity Modularity is generally desirable, especially in large, complicated programs. Inputs are usua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MacBinary
MacBinary is a file format that combines the two ''forks'' of a classic Mac OS file into a single file, along with Hierarchical File System, HFS's extended metadata. The resulting file is suitable for transmission over File Transfer Protocol, FTP, the World Wide Web, and electronic mail. The documents can also be stored on computers that run operating systems with no HFS support, such as Unix or Microsoft Windows, Windows. MacBinary was widely supported on the Macintosh and was built into most communications programs on that platform. Similar solutions were built into most data compression applications on the Mac, and although these did not require MacBinary to survive transmission across non-Mac systems, MacBinary was often added in these cases to preserve longer filenames and other features. The dual-fork nature of the HFS system was not used on Mac OS X, and MacBinary has largely disappeared. Description In contrast to other computers of the era, Macintosh applications include ...

B Protocol
The B protocol, or CIS B, is a file transfer protocol developed for the CompuServe Information Service, and implemented in 1981. The protocol was later expanded in the QuickB version (which was an asynchronous version of the standard protocol) and later the enhanced B Plus version. It was a fairly advanced protocol for its era, supporting efficient transfers of files, commands and other data as well, and could be used in both directions at the same time in certain modes. These advanced features were not widely used, but could be found in a small number of client-side packages. Since B protocol was designed only to work within the CompuServe, most third-party communications clients of the day were not compatible with it. Notable exceptions were Tera Term and Datastorm's ProComm Plus on the PC which featured the ability to listen for the command on the active communications port, and ZTerm on the Mac which allowed auto-starting transfers. This development was part of a wider tren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kermit (protocol)
Kermit is a computer file transfer/management protocol and a set of communications software tools primarily used in the early years of personal computing in the 1980s. It provides a consistent approach to file transfer, terminal emulation, script programming, and character set conversion across many different computer hardware and operating system platforms. Technical The Kermit protocol supports text and binary file transfers on both full-duplex and half-duplex 8-bit and 7-bit serial connections in a system- and medium-independent fashion, and is implemented on hundreds of different computer and operating system platforms. On full-duplex connections, a sliding window protocol is used with selective retransmission which provides excellent performance and error recovery characteristics. On 7-bit connections, locking shifts provide efficient transfer of 8-bit data. When properly implemented, as in the Columbia University Kermit Software collection, its authors claim performance i ...
