Mensch Computer
The Mensch Computer is a personal computer system produced by the Western Design Center (WDC). It is based on the WDC 65C265 microcontroller, which implements the instruction sets of two microprocessors: the 16-bit W65C816/65816, and the 8-bit 6502. The computer is named after Bill Mensch, designer of the 6502 and subsequent series of microprocessor. The system is designed for hobbyists and people who enjoy computer programming, especially at the assembly language level, and includes a basic set of peripherals which can be expanded by the owner. Much software originally written for other computer systems which use the 65816 or 6502 instruction sets (such as the Nintendo Entertainment System, Super Nintendo, or Apple IIGS, among others) can be run on the Mensch Computer (either directly as binary object code or through reassembling the software source code), to the extent that such software does not rely on hardware configurations which differ from the Mensch Computer.

Personal Computer
A personal computer, commonly referred to as PC or computer, is a computer designed for individual use. It is typically used for tasks such as Word processor, word processing, web browser, internet browsing, email, multimedia playback, and PC game, gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. The term home computer has also been used, primarily in the late 1970s and 1980s. The advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people. Institutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with computers. While personal computer users may develop their applications, usually these systems run commercial software, free-of-charge software ("freeware"), which i ...

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 ...

Firmware
In computing Computing is any goal-oriented activity requiring, benefiting from, or creating computer, computing machinery. It includes the study and experimentation of algorithmic processes, and the development of both computer hardware, hardware and softw ..., firmware is software that provides low-level control of computing device Computer hardware, hardware. For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionality. For a more complex device, firmware may provide relatively low-level control as well as hardware abstraction Service (systems architecture), services to higher-level software such as an operating system. Firmware is found in a wide range of computing devices including personal computers, smartphones, home appliances, vehicles, computer peripherals and in many of the integrated circuits inside each of these larger systems. Firmware is stored in non-volatile memory either read-only memory (ROM) or progra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine Code Monitor
A machine code monitor ( machine language monitor) is software that allows a user to enter commands to view and change memory address, memory locations on a computer, with options to load and save memory contents from/to secondary storage. Some full-featured machine code monitors provide detailed control ("single-stepping") of the execution of machine language programs (much like a debugger), and include absolute-address Assembly language#Assembler, code assembly and disassembler, disassembly capabilities. Motorola published the MIKBUG ROM monitor for the 6800 in 1973 and the BUFFALO ROM monitor for the Motorola 68HC11, 68HC11. Machine code monitors became popular during the home computer era of the 1970s and 1980s and were sometimes available as resident firmware in some computers (e.g., the built-in monitors in the Commodore 128, Zenith Z-89, Heathkit H89 and Zenith laptops). Often, computer manufacturers rely on their ROM-resident monitors to permit users to reconfigure their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Read-only Memory
Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware. Software applications, such as video games, for programmable devices can be distributed as ROM cartridge, plug-in cartridges containing ROM. Strictly speaking, ''read-only memory'' refers to hard-wired memory, such as diode matrix or a #Solid-state ROM, mask ROM integrated circuit (IC), that cannot be electronically changed after manufacture. Although discrete circuits can be altered in principle, through the addition of Jump wire, bodge wires and the removal or replacement of components, ICs cannot. Correction of errors, or updates to the software, require new devices to be manufactured and to replace the installed device. Floating-gate ROM semiconductor ...

Source Code
In computing, source code, or simply code or source, is a plain text computer program written in a programming language. A programmer writes the human readable source code to control the behavior of a computer. Since a computer, at base, only understands machine code, source code must be Translator (computing), translated before a computer can Execution (computing), execute it. The translation process can be implemented three ways. Source code can be converted into machine code by a compiler or an assembler (computing), assembler. The resulting executable is machine code ready for the computer. Alternatively, source code can be executed without conversion via an interpreter (computing), interpreter. An interpreter loads the source code into memory. It simultaneously translates and executes each statement (computer science), statement. A method that combines compilation and interpretation is to first produce bytecode. Bytecode is an intermediate representation of source code tha ...

Object Code
In computing, object code or object module is the product of an assembler or compiler In computing, a compiler is a computer program that Translator (computing), translates computer code written in one programming language (the ''source'' language) into another language (the ''target'' language). The name "compiler" is primaril .... In a general sense, object code is a sequence of statements or instructions in a computer language, usually a machine code language (i.e., binary) or an intermediate language such as register transfer language (RTL). The term indicates that the code is the goal or result of the compiling process, with some early sources referring to source code as a "subject program". Details Object files can in turn be linked to form an executable file or library file. In order to be used, object code must either be placed in an executable file, a library file, or an object file. Object code is a portion of machine code that has not yet been linked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple IIGS
The Apple IIGS (styled as II) is a 16-bit personal computer produced by Apple Inc., Apple Computer beginning in September 1986. It is the fifth and most powerful model of the Apple II family. The "GS" in the name stands for "Graphics and Sound", referring to its enhanced multimedia hardware, especially the state-of-the-art audio. It is compatible with earlier Apple II models, and Apple initially sold a kit for converting an Apple IIe into a IIGS. The system is a radical departure otherwise, with a WDC 65C816 microprocessor, 256 KB or 1 MB of random-access memory expandable to 8 MB, resolution and color similar to the Amiga and Atari ST, and a 32 channel Ensoniq wavetable synthesis chip. Bundled with a computer mouse, mouse, it is the first computer from Apple with a color graphical user interface (color was introduced on the Macintosh II six months later) and the Apple Desktop Bus interface for keyboards, mice, and other input devices. The IIGS blurred the lines between the App ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Super Nintendo Entertainment System
The Super Nintendo Entertainment System, commonly shortened to Super Nintendo, Super NES or SNES, is a Fourth generation of video game consoles, 16-bit home video game console developed by Nintendo that was released in 1990 in Japan, 1991 in North America, 1992 in Europe and Oceania and 1993 in South America. In Japan, it is called the In South Korea, it is called the Super Comboy and was distributed by SK Hynix, Hyundai Electronics. The system was released in Brazil on August 30, 1993, by Playtronic. In Russia and Commonwealth of Independent States, CIS, the system was distributed by Steepler from 1994 until 1996. Although each version is essentially the same, several forms of regional lockout prevent cartridges for one version from being used in other versions. The Super NES is Nintendo's second programmable home console, following the Nintendo Entertainment System (NES). The console introduced advanced graphics and sound capabilities compared with other systems at the time. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nintendo Entertainment System
The Nintendo Entertainment System (NES) is an 8-bit home video game console developed and marketed by Nintendo. It was first released in Japan on 15 July 1983 as the and was later released as the redesigned NES in several test markets in the United States beginning on 18 October 1985, followed by a nationwide launch on 27 September 1986. The NES was distributed in Europe, Australia, and parts of Asia throughout the 1980s under various names. As a third-generation console, it mainly competed with Sega's Master System. Nintendo president Hiroshi Yamauchi called for a simple, cheap console that could run arcade games on cartridges. The Famicom was designed by lead architect Masayuki Uemura, with its controller design reused from Nintendo's portable Game & Watch hardware. The western model was redesigned by Nintendo of America designers Lance Barr and Don James to resemble a video cassette recorder. Nintendo released add-ons such as the NES Zapper, a light gun for shootin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peripheral
A peripheral device, or simply peripheral, is an auxiliary hardware device that a computer uses to transfer information externally. A peripheral is a hardware component that is accessible to and controlled by a computer but is not a core component of the computer. A peripheral can be categorized based on the direction in which information flows relative to the computer: * The computer receives data from an '' input device''; examples: mouse, keyboard, scanner, game controller, microphone and webcam * The computer sends data to an '' output device''; examples: monitor, printer, headphones, and speakers * The computer sends and receives data via an ''input/output device''; examples: storage device (such as disk drive, solid-state drive, USB flash drive, memory card and tape drive), modem, router, gateway and network adapter Many modern electronic devices, such as Internet-enabled digital watches, video game consoles, smartphones, and tablet computers, have in ...

Computer Programming
Computer programming or coding is the composition of sequences of instructions, called computer program, programs, that computers can follow to perform tasks. It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing source code, code in one or more programming languages. Programmers typically use high-level programming languages that are more easily intelligible to humans than machine code, which is directly executed by the central processing unit. Proficient programming usually requires expertise in several different subjects, including knowledge of the Domain (software engineering), application domain, details of programming languages and generic code library (computing), libraries, specialized algorithms, and Logic#Formal logic, formal logic. Auxiliary tasks accompanying and related to programming include Requirements analysis, analyzing requirements, Software testing, testing, debugging (investigating and fixing problems), imple ...
