Texas Instruments TI-99/4
The TI-99/4 and TI-99/4A are home computers released by Texas Instruments in 1979 and 1981, respectively. Based on the Texas Instruments TMS9900 microprocessor originally used in minicomputers, the TI-99/4 was the first 16-bit home computer. The associated video display controller provides color graphics and sprite support which were only comparable with those of the Atari 400 and 800 released a month after the TI-99/4. The calculator-style keyboard of the TI-99/4 was cited as a weak point, and TI's reliance on ROM cartridges and their practice of limiting developer information to select third parties resulted in a lack of software for the system. The TI-99/4A was released in June 1981 to address some of these issues with a simplified internal design, full-travel keyboard, improved graphics, and a unique expansion system. At half the price of the original model, sales picked up significantly and TI supported the 4A with peripherals, including a speech synthesizer and a "Perip ...

SG-1000
The is a home video game console manufactured by Sega. It was Sega's first entry into the home video game hardware business. Developed in response to a downturn in arcades starting in 1982, the SG-1000 was created on the advice of Hayao Nakayama, president of Sega's Japanese arm, and was released on July 15, 1983, the same day that Nintendo released the Family Computer in Japan. It also saw limited release in Australia and New Zealand. The SG-1000 was released in several forms, including the SC-3000 computer and the redesigned SG-1000 II released in 1984. The SG-1000 and the SC-3000 both support a library of 76 ROM cartridge games and 29 Sega My Card games. A third iteration of the console, the Sega Mark III, was released in 1985. It provided an improved custom video display processor over previous iterations and served as the basis for the Master System in 1986, Sega's first internationally released console. All SG-1000 games are fully compatible with the Mark III and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Video Display Controller
A video display controller or VDC (also called a display engine or display interface) is an integrated circuit which is the main component in a video-signal generator, a device responsible for the production of a TV video signal in a computing or game system. Some VDCs also generate an audio signal, but that is not their main function. VDCs were used in the home computers of the 1980s and also in some early video picture systems. The VDC is the main component of the video signal generator logic, responsible for generating the timing of video signals such as the horizontal and vertical synchronization signals and the blanking interval signal. Sometimes other supporting chips were necessary to build a complete system, such as RAM to hold pixel data, ROM to hold character fonts, or some discrete logic such as shift registers. Most often the VDC chip is completely integrated in the logic of the main computer system, (its video RAM appears in the memory map of the main CPU), bu ...

NABU Network
The NABU Network (Natural Access to Bi-directional Utilities) was an early home computer system which was linked to a precursor of the World Wide Web, operating over cable TV. It operated from 1982 to 1985, primarily in Ottawa, Canada. Its functionality was then revolutionary, though it was not a commercial success. It has been called "The Internet — 10 years ahead of its time" (even though elements of the History of the Internet, history of the internet predate it). Functionality Families, schools, or individuals would purchase a NABU Personal Computer, which would be connected via cable TV to NABU's servers. In addition to normal PC capabilities of the time, the computer could download software and information content through the cable feed and could upload primitive information back up to the servers. Applications included games, the programming language Logo programming language, Logo, news/current events, and rudimentary PC banking/shopping. At its peak, approximately ...

ColecoVision
ColecoVision is a second-generation home video-game console developed by Coleco and launched in North America in August 1982. It was released a year later in Europe by CBS Electronics as the CBS ColecoVision. The console offered a closer experience to more powerful arcade video games compared to competitors such as the Atari 2600 and Intellivision. The initial catalog of twelve games on ROM cartridge included the first home version of Nintendo's ''Donkey Kong'' as the pack-in game. Approximately 136 games were published between 1982 and 1984, including Sega's ''Zaxxon'' and some ports of lesser known arcade games that found a larger audience on the console, such as '' Lady Bug'', ''Cosmic Avenger'', and ''Venture''. Coleco released a series of hardware add-ons and special controllers to expand the capabilities of the console. "Expansion Module #1" allows the system to play Atari 2600 cartridges. A later module converts ColecoVision into the Coleco Adam home computer. Coleco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SV-318
The SV-318 is the basic model of the Spectravideo range. It was fitted with a chiclet style keyboard, difficult to use, alongside which sat a combination cursor pad/joystick. This is a disc-shaped affair with a hole in the centre; put a red plastic 'stick' in the hole and it is a built-in joystick, remove the stick and it is a directional arrow pad for word processing etc. This machine also had only 16 KB of user RAM (plus an additional 16 KB of video RAM), which limited its usefulness, though this could be expanded via an external peripheral box. This machine is basically identical to its big brother the SV-328, the only differences being in the keyboard and amount of memory. The ROM, expandability, mainboard and case of the two machines were identical. Reference to the operating system Microsoft Extended BASIC is not to be confused with MSX BASIC, although some marketing at the time claimed that Microsoft Extended is what MSX stood for. The SV-318 is not fully compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SV-328
The SV-328 is an 8-bit home computer introduced by Spectravideo in June 1983. It was the business-targeted model of the Spectravideo range, sporting a compact full-travel keyboard with numeric keypad. It had 80 KB RAM (64 KB available for software, remaining 16 KB video memory), a respectable amount for its time. Other than the keyboard and RAM, this machine was identical to its little brother, the SV-318. The SV-328 is the design on which the MSX standard was based. Spectravideo's MSX-compliant successor to the 328, the SV-728, looks almost identical, the only immediately noticeable differences being a larger cartridge slot in the central position (to fit MSX standard cartridges), lighter shaded keyboard and the MSX badging. Reference to the operating system Microsoft Extended BASIC is not to be confused with MSX BASIC, although some marketing at the time claimed that Microsoft Extended is what MSX stood for. More than 130 games were released for the system. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tatung Einstein
The Tatung Einstein was an eight-bit home/personal computer produced by Taiwanese corporation Tatung, designed in Bradford, England at Tatung's research laboratories and assembled in Bridgnorth and Telford, England. It was aimed primarily at small businesses. History The Tatung Einstein TC-01 was released in the United Kingdom in the summer of 1984, and 5,000 were exported to Taipei later that year. A Tatung monitor (monochrome or colour) and dot matrix printer were also available as options, plus external disc drives and an 80 column display card. It was also capable of running ZX Spectrum software with the "Speculator" addon. More expensive than most of its rivals, the Einstein was popular with contemporary programmers as a development machine but was commercially unsuccessful. A later revised version, called the Tatung Einstein 256 and released in 1985, suffered a similar fate. Design The machine was physically large, with an option for one or two built-in three-inc ...
