ANTIC
Alphanumeric Television Interface Controller (ANTIC) is an LSI ASIC dedicated to generating 2D computer graphics to be shown on a television screen or computer display. Under the direction of Jay Miner, the chip was designed in 1977-1978 by Joe Decuir, Francois Michel, and Steve Smith for the Atari 8-bit family of home computers first released in 1979 and was patented by Atari, Inc. Atari, Inc. was an American video game developer and home computer company founded in 1972 by Nolan Bushnell and Ted Dabney. Atari was a key player in the formation of the video arcade and video game industry. Based primarily around the Sunny ... in 1981. ANTIC is also used in the 1982 Atari 5200 video game console, which shares most of the same hardware as the 8-bit computers. For every frame of video, ANTIC reads a program of instruction set, instructions to define the playfield, or background graphics, then delivers a data stream to the companion CTIA and GTIA, CTIA or GTIA chip which ...

GTIA
Color Television Interface Adaptor (CTIA) and its successor Graphic Television Interface Adaptor (GTIA) are custom chips used in the Atari 8-bit family of computers and in the Atari 5200 home video game console. In these systems, a CTIA or GTIA chip works together with ANTIC to produce the video display. ANTIC generates the playfield graphics (text and bitmap) while CTIA/GTIA provides the color for the playfield and adds overlay objects known as player/missile graphics ( sprites). Under the direction of Jay Miner, the CTIA/GTIA chips were designed by George McLeod with technical assistance of Steve Smith. ''Color Television Interface Adaptor'' and ''Graphic Television Interface Adaptor'' are names of the chips as stated in the Atari field service manual. Various publications named the chips differently, sometimes using the alternative spelling ''Adapter'' or ''Graphics'', or claiming that the "C" in "CTIA" stands for Colleen/Candy and "G" in "GTIA" is for George.

Atari 8-bit Family
The Atari 8-bit family is a series of 8-bit home computers introduced by Atari, Inc. in 1979 as the Atari 400 and Atari 800. The series was successively upgraded to Atari 1200XL , Atari 600XL, Atari 800XL, Atari 65XE, Atari 130XE, Atari 800XE, and Atari XEGS, the last discontinued in 1992. They differ primarily in packaging, each based on the MOS Technology 6502 central processing unit, CPU at and the same custom coprocessor chips. As the first home computer architecture with coprocessors, it has graphics and sound more advanced than most contemporary machines. Video games were a major draw, and first-person space combat simulator ''Star Raiders'' is considered the platform's killer app. The plug-and-play peripherals use the Atari SIO serial bus, with one developer eventually also co-patenting USB. While using the same internal technology, the Atari 800 was sold as a high-end model, while the 400 was more affordable. The 400 has a pressure-sensitive, spillproof membrane keyboar ...

Horizontal Blank Interrupt
A raster interrupt (also called a horizontal blank 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. Such an interrupt provides a mechanism for graphics registers to be changed mid-frame, so they have different values above and below the interrupt point. This allows a single-color object such as the background or the screen border to have multiple horizontal color bands, for example. Or, for a hardware sprite to be repositioned to give the illusion that there are more sprites than a system supports. The limitation is that changes only affect the portion of the display below the interrupt. They don't allow more colors or more sprites on a single scan line. Modern protected mode operating systems ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antic (magazine)
''Antic'' () was a print magazine devoted to the Atari 8-bit family of home computers and later the Atari ST. It was named after the ANTIC chip in the 8-bit line which, in concert with CTIA or GTIA, generates the display. The magazine was published from April 1982 until June/July 1990. ''Antic'' printed type-in programs (usually in BASIC), reviews, and tutorials, among other articles. Each issue contained one type-in game as "Game of the Month." In 1986, ''STart'' magazine was spun off to exclusively cover the Atari ST line. Its main rival in the United States was ''ANALOG Computing'', another long-lived magazine devoted to the Atari 8-bit line. Multi-system magazines ''COMPUTE!'' and ''Family Computing'' also served Atari 8-bit owners with type-in programs. Starting in 1984, the catalog for Antic Software was bound into issues of ''Antic''. History NASA programmer Jim Capparell was an early Atari 8-bit owner. He quit his job on 15 January 1982 to found a magazine for the comp ...

Atari 5200
The Atari 5200 SuperSystem or simply Atari 5200 is a home video game console introduced in 1982 by Atari, Inc. as a higher-end complement for the popular Atari Video Computer System. The VCS was renamed to the Atari 2600 at the time of the 5200's launch. Created to compete with Mattel's Intellivision, the 5200 wound up a direct competitor of ColecoVision shortly after its release. While the Coleco system shipped with the first home version of Nintendo's ''Donkey Kong'', the 5200 included the 1978 arcade game ''Super Breakout'' which had already appeared on the Atari 8-bit family and Atari VCS in 1979 and 1981 respectively. The CPU and the graphics and sound hardware are almost identical to that of the Atari 8-bit computers, although software is not directly compatible between the two systems. The 5200's controllers have an analog joystick and a numeric keypad along with start, pause, and reset buttons. The 360-degree non-centering joystick was touted as offering more control than ...

Display List
A display list (or ''display file'') is a series of graphics commands that define an output image. The image is created ( ''rendered'') by executing the commands to combine various primitives. This activity is most often performed by specialized display or processing hardware partly or completely independent of the system's CPU for the purpose of freeing the CPU from the overhead of maintaining the display, and may provide output features or speed beyond the CPU's capability. For a display device without a frame buffer, such as vector graphics displays, the commands were executed every fraction of a second to maintain and animate the output. In modern systems, the commands need only be executed when they have changed or in order to refresh the output (e.g., when restoring a minimized window). A display list can represent both two- and three-dimensional scenes. Systems that make use of a display list to store the scene are called retained mode systems as opposed to immediate mode s ...
