The Apple II is an early personal computer that was created by Apple Inc. It was one of the first successful mass-produced microcomputer products, and it played a significant role in the early development of the personal computer industry. It has an 8-bit microprocessor.
The Atari 7800 ProSystem, or simply the Atari 7800, is a home video game console officially released by Atari Corporation in 1986 as the successor to both the Atari 2600 and Atari 5200. It can run almost all Atari 2600 cartridges, making it one of the first consoles with backward compatibility. It shipped with a different model of joystick from the 2600-standard CX40 and Pole Position II as the pack-in game. Most of the announced titles at launch were ports of 1981–1983 arcade video games.
The Commodore 64, also known as the C64, is an 8-bit home computer introduced in January 1982 by Commodore International. It has been listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 12.5 and 17 million units. Volume production started in early 1982, marketing in August for US$595. Preceded by the VIC-20 and Commodore PET, the C64 took its name from its 64 kilobytes(65,536 bytes) of RAM. With support for multicolor sprites and a custom chip for waveform generation, the C64 could create superior visuals and audio compared to systems without such custom hardware.
The Fairchild Channel F, short for "Channel Fun", is a video game console, the first to be based on a microprocessor and to use ROM cartridges instead of having games built-in. It was released by Fairchild Camera and Instrument in November 1976 across North America at a retail price of US$169.95. It was launched as the "Video Entertainment System", but when Atari released its Video Computer System the next year, Fairchild rebranded their machine as "Channel F" while keeping the Video Entertainment System descriptor.
The Game Boy Color is an 8-bit handheld game console, manufactured by Nintendo, which was released in Japan on October 21, 1998, and to international markets that November. It is the successor to the Game Boy and is part of its product line. Compared to the original, the Game Boy Color features a color TFT screen rather than monochrome, a processor that operates twice as fast, and has four times as much memory. It retains backward compatibility with games initially developed for its predecessor. However, despite these improvements, reviewers consider the Game Boy Color an evolution rather than a revolutionary leap in handheld gaming technology.
The Intellivision is a home video game console released by Mattel Electronics in 1979. The name is a portmanteau of "intelligent television". Development began in 1977, the same year as the launch of its main competitor, the Atari 2600. In 1984, Mattel sold its video game assets to a former Mattel Electronics executive and investors, eventually becoming INTV Corporation. Game development ran from 1978 to 1990, when the Intellivision was discontinued. From 1980 to 1983, more than 3.75 million consoles were sold. As per Intellivision Entertainment the final tally through 1990 is somewhere between 4.5 and 5 million consoles sold.
The Magnavox Odyssey 2, also known as Philips Odyssey 2, is a second generation home video game console that was released in 1978. It was sold in Europe as the Philips Videopac G7000, in Brazil and Peru as the Philips Odyssey and in Japan as Odyssey2. The Odyssey 2 was one of the five major home consoles prior to the 1983 video game market crash, along with Atari 2600, Atari 5200, Intellivision and ColecoVision.
The RadioShack TRS-80 Color Computer, later marketed as the Tandy Color Computer, is a series of home computers developed and sold by Tandy Corporation. Despite sharing a name with the earlier TRS-80, the Color Computer is a completely different system and a radical departure in design based on the Motorola 6809E processor rather than the Zilog Z80 of earlier models.
The Atari 8-bit computers, formally launched as the Atari Home Computer System, are a series of 8-bit home computers introduced by Atari, Inc. in 1979 with the Atari 400 and Atari 800. It is the first home computer architecture with coprocessors, enabling more advanced graphics and sound than most of its contemporaries. Video games are key to its software library, and the 1980 first-person space combat simulator Star Raiders is considered the platform's killer app.
The VIC-20 is an 8-bit home computer that was sold by Commodore Business Machines. The VIC-20 was announced in 1980, roughly three years after Commodore's first personal computer, the PET. The VIC-20 was the first computer of any description to sell one million units. It was described as "one of the first anti-spectatorial, non-esoteric computers by design...no longer relegated to hobbyist/enthusiasts or those with money, the computer Commodore developed was the computer of the future."
The Datamax UV-1 is a pioneering computer designed by a group of computer graphics artists working at the University of Illinois at Chicago, known as the Circle Graphics Habitat. It was primarily the brainchild of Tom DeFanti, who was trying to build a machine capable of running his GRASS programming language at a personal computer price point, a project they referred to as the Z-Box. As time went on the project evolved into a machine intended to be used to make high-quality color graphics for output to videotape, and later as a titling system for use by cable television companies. It represents what seems to be the first dedicated graphics workstation.
The Sorcerer is a home computer system released in 1978 by the video game company Exidy, later under their Exidy Systems subsidiary. Based on the Zilog Z80 and the general layout of the emerging S-100 standard, the Sorcerer was comparatively advanced when released, especially when compared to the contemporary more commercially successful Commodore PET and TRS-80. The basic design was proposed by Paul Terrell, formerly of the Byte Shop, a pioneering computer store.
The TI-99/4 and TI-99/4A are home computers released by Texas Instruments in 1979 and 1981, respectively. The TI-99 series competed against home computers such as the Apple II, TRS-80, Atari 400/800, and VIC-20.
The Commodore Plus/4 is a home computer released by Commodore International in 1984. The "Plus/4" name refers to the four-application ROM-resident office suite ; it was billed as "the productivity computer with software built in".
The VIC (Video Interface Chip), specifically known as the MOS Technology 6560 (NTSC version) / 6561 (PAL version), is the integrated circuit chip responsible for generating video graphics and sound in the VIC-20 home computer from Commodore. It was originally designed for applications such as low cost CRT terminals, biomedical monitors, control system displays and arcade or home video game consoles.
The VIC-II, specifically known as the MOS Technology 6567/6566/8562/8564, 6569/8565/8566 (PAL), is the microchip tasked with generating Y/C video signals and DRAM refresh signals in the Commodore 64 and Commodore 128 home computers.
The Television Interface Adaptor (TIA) is the custom computer chip, along with a variant of the MOS Technology 6502 constituting the heart of the 1977 Atari Video Computer System game console. The TIA generates the screen display, sound effects, and reads the controllers. At the time the Atari VCS was designed, even small amounts of RAM were expensive. The chip was designed around not having a frame buffer, instead requiring detailed programming to create even a simple display.
In the history of video games, the second-generation era refers to computer and video games, video game consoles, and handheld video game consoles available from 1976 to 1992. Notable platforms of the second generation include the Fairchild Channel F, Atari 2600, Intellivision, Odyssey 2, and ColecoVision. The generation began in November 1976 with the release of the Fairchild Channel F. This was followed by the Atari 2600 in 1977, Magnavox Odyssey² in 1978, Intellivision in 1980 and then the Emerson Arcadia 2001, ColecoVision, Atari 5200, and Vectrex, all in 1982. By the end of the era, there were over 15 different consoles. It coincided with, and was partly fuelled by, the golden age of arcade video games. This peak era of popularity and innovation for the medium resulted in many games for second generation home consoles being ports of arcade games. Space Invaders, the first "killer app" arcade game to be ported, was released in 1980 for the Atari 2600, though earlier Atari-published arcade games were ported to the 2600 previously. Coleco packaged Nintendo's Donkey Kong with the ColecoVision when it was released in August 1982.
A raster interrupt is an interrupt signal in a legacy computer system which is used for display timing. It is usually, though not always, generated by a system's graphics chip as the scan lines of a frame are being readied to send to the monitor for display. The most basic implementation of a raster interrupt is the vertical blank interrupt.
