ARexx
ARexx is a Rexx interpreter for Amiga, written in 1987 by William S. Hawes, with a number of Amiga-specific features beyond standard Rexx. An ARexx script can communicate with software that implements an ''ARexx port''. An Amiga application can define a set of commands and functions for ARexx to address, thus making the capabilities of the software available to an ARexx script. Several applications support running an ARexx script as a macro. An ARexx script can execute commands and functions in multiple applications which allows a script to integrate the functionality of the applications. For example, an ARexx script could extract data from a database, insert the data into a spreadsheet to perform calculations on the data, then insert tables and charts based on the results into a word processor document. ARexx allows a script to communicate with applications that are "ARexx compatible" able to receive commands from ARexx and execute them. Notable examples include: the ''Mi ...

AmigaOS
AmigaOS is a family of proprietary native operating systems of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola Motorola 68000 family, 68000 series of 16-bit and 32-bit microprocessors. Later versions, after Commodore's demise, were developed by Haage & Partner (AmigaOS 3.5 and 3.9) and then Hyperion Entertainment (AmigaOS 4.0-4.1). A PowerPC microprocessor is required for the most recent AmigaOS 4-release. AmigaOS is a single-user operating system based on a preemptive multitasking kernel (operating system), kernel, called Exec (Amiga), Exec. It includes an abstraction of the Amiga's hardware, a disk operating system called ''AmigaDOS'', a windowing system Application programming interface, API called Intuition (Amiga), ''Intuition'', and a desktop environment and file manager called Workbench (AmigaOS), ''Workbenc ...

AmigaTeX
__NOTOC__ The computer program AmigaTeX is a port of Knuth's typesetting program TeX, which was originally written in WEB. To create AmigaTeX, that source was translated to C by Tomas Rokicki. This manual translation was necessary because of the lack of a suitable Pascal compiler for the Amiga computer. When development of AmigaTeX commenced, WEB depended on Pascal and Web2c was not yet an available alternative. Features AmigaTeX has several features not available in standard TeX: * ARexx port for example with CygnusEd * Preview * Interchange File Format graphics integration See also * LuaTeX * XeTeX XeTeX ( or ; see also Pronouncing and writing "TeX") is a TeX typesetting engine using Unicode and supporting modern font technologies such as OpenType, Graphite and Apple Advanced Typography (AAT).

MorphOS
MorphOS is an AmigaOS-like operating system designed for Power and PowerPC based computers. The core, based on the Quark microkernel, is proprietary, although several libraries and other parts are open source, such as the Ambient desktop. The project began in 1999 and it was produced for the Pegasos computer, as well as PowerUP accelerator equipped Amiga computers, and a series of Freescale development boards that use the Genesi firmware, including the Efika and mobileGT. Since then MorphOS has been ported to Apple's Mac mini, eMac, Power Mac G4 and limited support for Power Mac G5. It is binary compatible with software written for Motorola 68k-based Amiga computers. History The project began in 1999, based on the Quark microkernel. The earliest versions of MorphOS ran only via PPC accelerator cards on the Amiga computers, and required portions of AmigaOS to fully function. A collaborative effort between the companies bPlan (of which the lead MorphOS developer is a pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Application Software
Application software is any computer program that is intended for end-user use not operating, administering or programming the computer. An application (app, application program, software application) is any program that can be categorized as application software. Common types of applications include word processor, media player and accounting software. The term ''application software'' refers to all applications collectively and can be used to differentiate from system and utility software. Applications may be bundled with the computer and its system software or published separately. Applications may be proprietary or open-source. The short term ''app'' (coined in 1981 or earlier) became popular with the 2008 introduction of the iOS App Store, to refer to applications for mobile devices such as smartphones and tablets. Later, with introduction of the Mac App Store (in 2010) and Windows Store (in 2011), the term was extended in popular use to include desktop a ...

PowerPC
PowerPC (with the backronym Performance Optimization With Enhanced RISC – Performance Computing, sometimes abbreviated as PPC) is a reduced instruction set computer (RISC) instruction set architecture (ISA) created by the 1991 Apple Inc., Apple–IBM–Motorola alliance, known as AIM alliance, AIM. PowerPC, as an evolving instruction set, has been named Power ISA since 2006, while the old name lives on as a trademark for some implementations of Power Architecture–based processors. Originally intended for personal computers, the architecture is well known for being used by Apple's desktop and laptop lines from 1994 until 2006, and in several videogame consoles including Microsoft's Xbox 360, Sony's PlayStation 3, and Nintendo's GameCube, Wii, and Wii U. PowerPC was also used for the Curiosity (rover), Curiosity and Perseverance (rover), Perseverance rovers on Mars and a variety of satellites. It has since become a niche architecture for personal computers, particularly with A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assembly Language
In computing, assembly language (alternatively assembler language or symbolic machine code), often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. Assembly language usually has one statement per machine instruction (1:1), but constants, comments, assembler directives, symbolic labels of, e.g., memory locations, registers, and macros are generally also supported. The first assembly code in which a language is used to represent machine code instructions is found in Kathleen and Andrew Donald Booth's 1947 work, ''Coding for A.R.C.''. Assembly code is converted into executable machine code by a utility program referred to as an '' assembler''. The term "assembler" is generally attributed to Wilkes, Wheeler and Gill in their 1951 book '' The Preparation of Programs for an Electronic Dig ...

68000
The Motorola 68000 (sometimes shortened to Motorola 68k or m68k and usually pronounced "sixty-eight-thousand") is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector. The design implements a 32-bit instruction set, with 32-bit registers and a 16-bit internal data bus. The address bus is 24 bits and does not use memory segmentation, which made it easier to program for. Internally, it uses a 16-bit data arithmetic logic unit (ALU) and two more 16-bit ALUs used mostly for addresses, and has a 16-bit external data bus. For this reason, Motorola termed it a 16/32-bit processor. As one of the first widely available processors with a 32-bit instruction set, large unsegmented address space, and relatively high speed for the era, the 68k was a popular design through the 1980s. It was widely used in a new generation of personal computers with graphical user interfaces, including the Macintosh 128K, Amiga, ...

Amiga
Amiga is a family of personal computers produced by Commodore International, Commodore from 1985 until the company's bankruptcy in 1994, with production by others afterward. The original model is one of a number of mid-1980s computers with 16-bit or 16/32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. These include the Atari ST as well as the Macintosh 128K, Macintosh and Acorn Archimedes. The Amiga differs from its contemporaries through custom hardware to accelerate graphics and sound, including sprite (computer graphics), sprites, a blitter, and four channels of sample-based audio. It runs a pre-emptive multitasking operating system called AmigaOS, with a desktop environment called Workbench (AmigaOS), Workbench. The Amiga 1000, based on the Motorola 68000 microprocessor, was released in July 1985. Production problems kept it from becoming widely available until early 1986. While ...

Metacomco
MetaComCo (MCC) was a computer systems software company started in 1981 and based in Bristol, England by Peter Mackeonis and Derek Budge. A division of Tenchstar, Ltd. MetaComCo's first product was an MBASIC compatible interpreter for IBM PCs, which was licensed by Peter Mackeonis to Digital Research in 1982, and issued as the Digital Research Personal Basic, running under CP/M. Other computer languages followed, also licensed by Digital Research and MetaComCo established an office in Pacific Grove, California, to service their United States customers. In 1984 Dr. Tim King joined the company, bringing with him a version of the operating system TRIPOS for the Motorola 68000 processor which he had previously worked on whilst a researcher at the University of Cambridge. This operating system was used as the basis of AmigaDOS (file-related functions of AmigaOS); MetaComCo won the contract from Commodore because the original planned Amiga disk operating system called Commodore A ...

Lattice C
The Lattice C Compiler was released in June 1982 by Lifeboat Associates and was the first C compiler for the IBM Personal Computer. The compiler sold for $500 and would run on PC DOS or MS-DOS (which at the time were the same product with different brandings). The first hardware requirements were given as 96KB of RAM and one (later two) floppy drives. It was ported to many other platforms, such as mainframes ( MVS), minicomputers ( VMS), workstations (UNIX), OS/2, Amiga, Atari ST, and Sinclair QL. The compiler was subsequently repackaged by Microsoft under a distribution agreement as Microsoft C version 2.0. Microsoft developed their own C compiler that was released in April 1985 as Microsoft C Compiler 3.0. Lattice was purchased by SAS Institute in 1987 and rebranded as SAS/C. After this, support for other platforms dwindled until compiler development ceased for all platforms except IBM mainframes. The product is still available in versions that run on other platforms, but t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
