List Of 8-bit Computer Hardware Palettes
This is a list of notable 8-bit computer palette (computing), color palettes, and graphics, which were primarily manufactured from 1975 to 1985. Although some of them use List of monochrome and RGB color formats#Regular RGB palettes, RGB palettes, more commonly they have 4, 16 or more color palettes that are not bit nor level combinations of RGB primaries, but fixed ROM/circuitry colors selected by the manufacturer. Due to mixed-bit architectures, the ''n''-bit distinction is not always a strict categorization. Another common mistake is the assumption that a color palette of a given computer is what it can display all at once. Resolution is also a crucial aspect when criticizing an 8-bit computer, as many offer different modes with different amounts of colors on screen, and different resolutions, with the intent of trading off resolution for color, and vice versa. : 3-bit RGB palettes Systems with a 3-bit RGB palette use 1 bit for each of the red, green and blue color components. ...

8-bit
In computer architecture, 8-bit Integer (computer science), integers or other Data (computing), data units are those that are 8 bits wide (1 octet (computing), octet). Also, 8-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on processor register, registers or Bus (computing), data buses of that size. Memory addresses (and thus address buses) for 8-bit CPUs are generally larger than 8-bit, usually 16-bit. 8-bit microcomputers are microcomputers that use 8-bit microprocessors. The term '8-bit' is also applied to the character sets that could be used on computers with 8-bit bytes, the best known being various forms of extended ASCII, including the ISO/IEC 8859 series of national character sets especially ISO/IEC 8859-1, Latin 1 for English and Western European languages. The IBM System/360 introduced byte-addressable memory with 8-bit bytes, as opposed to bit-addressable or decimal digit-addressable or word-addressable memory ...

PC-9800 Series
The , commonly shortened to PC-98 or , is a lineup of Japanese 16-bit and 32-bit personal computers manufactured by NEC from 1982 to 2000. The platform established NEC's dominance in the Japanese personal computer market, and, by 1999, more than 18 million units had been sold. While NEC did not market these specific machines in the West, it sold the NEC APC series, which had similar hardware to early PC-98 models. The PC-98 was initially released as a business-oriented personal computer which had backward compatibility with the successful PC-8800 series. The range of the series has expanded, and in the 1990s it was used in a variety of industry fields including education and hobbies. NEC succeeded in attracting third-party suppliers and a wide range of users, and the PC-98 dominated the Japanese PC market with more than 60% market share by 1991. IBM clones lacked sufficient graphics capabilities to easily handle Japan's multiple writing systems, in particular kanji with its tho ...

Teletext Character Set
This article covers technical details of the character encoding system defined by ETS 300 706, a standard for World System Teletext, and used for the Viewdata and Teletext variants of Videotex in Europe. Character sets The following tables show various Teletext character sets. Each character is shown with a potential Unicode equivalent if available. Space and control characters are represented by the abbreviations for their names. Control characters Control characters are used to set foreground and background color, character height, current default character set, and other attributes. In formats where compatibility with ECMA-48's C0 control codes such as and is not required, these control codes are sometimes mapped transparently to the Unicode C0 control code range (U+0000 through U+001F). Amongst C1 control code sets, the Videotex character set#C1 control codes, ITU T.101 C1 control codes for "Serial" Data Syntax 2, are mostly a transposition of the Teletext spacing cont ...

World System Teletext
World System Teletext (WST) is the name of a standard for encoding and displaying teletext information, which is used as the standard for teletext throughout Europe today. It was adopted into the international standard ITU-R, CCIR 653 (now ITU-R BT.653) of 1986 as CCIR Teletext System B. Development WST originally stems from the UK standard developed by the BBC and the UK Independent Broadcasting Authority in 1974 for teletext transmission, extended in 1976 as the Broadcast Teletext Specification. With some tweaks to allow for alternative Teletext character set, national character sets, and adaptations to the NTSC 525-line system as necessary, this was then promoted internationally as "World System Teletext". It was accepted by ITU-R, CCIR in 1986 under international standard CCIR 653 (now ITU-R BT.653) as one of four recognised standards for teletext worldwide (most commonly referred to as CCIR Teletext System B). WST in Europe Almost all television sets sold in Europe since the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philips VG5000
The VG5000μ is a computer created by Philips in 1984. It was manufactured in Le Mans by Radiotechnique (RTS) and marketed under the Philips, Radiotechnique, Radiola and Schneider Rundfunkwerke, Schneider brands. Not compatible with any other machines, it offered VG5000 BASIC (derived from Microsoft BASIC-80) as the operating system upon boot. Graphic ability was limited to a semigraphic symbol display, with the equivalent resolution of 320 x 250 in 8 colors. There are about forty games available for the system. 300 000 units were sold in 1984, according to an internal Philips report, with 500 000 predicted for 1985. Aimed at schools, it was unsuccessful and production ended in 1986. As of 2022, enthusiasts remain active in developing new Homebrew (video games), homebrew software and Emulator, emulators for the system.

Matra Alice
The Matra & Hachette Ordinateur Alice is a home computer sold in France beginning in 1983. It was a clone of the TRS-80 MC-10, produced through a collaboration between Matra and Hachette in France and Tandy Corporation in the United States. The Alice is distinguished by its bright red casing. Functionally, it is equivalent to the MC-10, with a Péritel (SCART) connector replacing the RF modulator for video output. The Alice never became a popular computer in its home country. It tried to invade schools by being part of the country's '' Plan Informatique pour Tous'' ("Information technology for everyone") programme, but Thomson won the whole deal. The original model had 4 kB of RAM and used a Motorola 6847 video display generator chip, as used in the Dragon 32 and Acorn Atom among others. At least three emulators for the system exist. Specifications The machine is similar to the TRS-80 MC-10, with the following specifications: * CPU: Motorola 6803 at 0.89 Mhz * RAM: 4 Ki ...

Maximite
Maximite Microcomputer is a Microchip PIC32 microcontroller-based microcomputer. Originally designed as a hobby kit, the Maximite was introduced in a three-part article in Silicon Chip magazine in autumn of 2011 by Australian designer Geoff Graham. The project consists of two main components — a main circuit board and the MMBasic Interpreter, styled after GW-BASIC. Versions Maximite version 2.7 is still an open source project. Several hobbyists have produced their own custom versions, often using commercially available prototyping circuit boards. Clones Several Maximite clones were designed and released in the months following its introduction. Some, such as the Maximite SM1, and Geoff Graham's latest version, the Mini-Maximite, are hardware- and software-compatible with the original design, but use a different form factor. Others, like the DuinoMite, from the Bulgarian company Olimex, have altered the hardware by adding Arduino headers. This makes it easier to use hard ...

Atari 2600
The Atari 2600, initially branded as the Atari Video Computer System (Atari VCS) from its release until November 1982, is a home video game console developed and produced by Atari, Inc. Released in September 1977, it popularized microprocessor-based hardware and games stored on swappable ROM cartridges, a format first used with the Fairchild Channel F in 1976. The VCS was bundled with two joystick controllers, a conjoined pair of paddle controllers, and a game cartridgeinitially '' Combat'' and later '' Pac-Man''. Atari was successful at creating arcade video games, but their development cost and limited lifespan drove CEO Nolan Bushnell to seek a programmable home system. The first inexpensive microprocessors from MOS Technology in late 1975 made this feasible. The console was prototyped as codename Stella by Atari subsidiary Cyan Engineering. Lacking funding to complete the project, Bushnell sold Atari to Warner Communications in 1976. The Atari VCS launched in 1977 with n ...

SECAM
SECAM, also written SÉCAM (, ''Séquentiel de couleur à mémoire'', French for ''color sequential with memory''), is an analog color television system that was used in France, some parts of Europe and Africa, and Russia. It was one of three major analog color television standards, the others being PAL and NTSC. This page primarily discusses the SECAM colour encoding system. The articles on broadcast television systems and analog television further describe frame rates, image resolution, and audio modulation. SECAM video is composite video because the luminance (luma, monochrome image) and chrominance (chroma, color applied to the monochrome image) are transmitted together as one signal. All the countries using SECAM are currently in the process of conversion, or have already converted to Digital Video Broadcasting (DVB), the new pan-European standard for digital television. SECAM remained a major standard into the 2000s. History Development of SECAM predates PAL, and be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh SE
The Macintosh SE is a personal computer designed, manufactured, and sold by Apple Computer, from March 1987 to October 1990. It marked a significant improvement on the Macintosh Plus design and was introduced by Apple at the same time as the Macintosh II. The SE retains the same Compact Macintosh form factor as the original Macintosh computer introduced three years earlier and uses the same design language used by the Macintosh II. An enhanced model, the SE/30, was introduced in January 1989; sales of the original SE continued. The Macintosh SE was updated in August 1989 to include a SuperDrive, with this updated version being called the "Macintosh SE FDHD" and later the "Macintosh SE SuperDrive". The Macintosh SE was replaced with the Macintosh Classic, a very similar model which retained the same central processing unit and form factor, but at a lower price point. Overview The Macintosh SE was introduced at the AppleWorld conference in Los Angeles on March 2, 1987. The " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinclair QL
The Sinclair QL (for ''Quantum Leap'') is a personal computer launched by Sinclair Research in 1984, as an upper-end counterpart to the ZX Spectrum. The QL was aimed at the serious home user and professional and executive users markets from small to medium-sized businesses and higher educational establishments, but failed to achieve commercial success. While the ZX Spectrum has an 8-bit Zilog Z80 as the CPU, the QL uses a Motorola 68008. The 68008 is a member of the Motorola 68000 family with 32-bit internal data registers, but an 8-bit external data bus. History left, Sinclair QL ROM "dongle" – needed to expand the internal 32 KB ROM to 48 KB in early QLs The QL was originally conceived in 1981 under the code-name ''ZX83'', as a portable computer for business users, with a built-in ultra-thin flat-screen CRT display similar to the later TV80 pocket TV, printer and modem. As development progressed it eventually became clear that the portability features were over- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
