Atari 7800

The Atari 7800 ProSystem was the first console from Atari, Inc. designed by an outside company: General Computer Corporation.{{Cite web|url=https://www.youtube.com/watch?v=ack4jr09qw0 | archive-url=https://ghostarchive.org/varchive/youtube/20211123/ack4jr09qw0| archive-date=2021-11-23 | url-status=live|title=The History of the Atari 7800 ProSystem with Steve Golson|website=YouTube| date=7 November 2016}}{{cbignore}} It was developed in 1983–84 with an intended mass market rollout in June 1984, but was canceled after the sale of the company to Tramel Technology Ltd on July 2, 1984. The project was originally called the Atari 3600.{{Cite web|url=http://www.atarimuseum.com/videogames/consoles/7800/7800menu/ |title=The Atari 7800 ProSystem |url-status=live |archive-url=https://archive.today/20130117172550/http://www.atarimuseum.com/videogames/consoles/7800/7800menu/ |archive-date=2013-01-17 }}

With a background in creating arcade games such as Food Fight, GCC designed the new system with a graphics architecture similar to arcade machines of the time. The CPU is a slightly customized 6502 processor, the Atari SALLY,{{cite magazine|title=When Pac Ruled the Earth|magazine=Electronic Gaming Monthly|issue=62|publisher=EGM Media, LLC|date=September 1994|page=18}} running at 1.79 MHz. By some measures the 7800 is more powerful, and by others less, than the 1983 Nintendo Entertainment System.{{cite web|title=7800 compared to the NES|url=https://sites.google.com/site/atari7800wiki/7800-compared-to-the-nes|website=Atari 7800 Programming}} It uses the 2600's Television Interface Adaptor chip, with the same restrictions, for generating two-channels of audio.

The 7800 was announced on May 21, 1984.{{cite press release |title=Atari unveils advanced video game that is expandable to introductory computer |publisher=Atari, Inc. |url=http://www.atari7800.org/museum/PressDoc1s.htm |access-date=2010-04-30 |date=1984-05-21}} Thirteen games were announced for the system's launch: Ms. Pac-Man, Pole Position II, Centipede, Joust, Dig Dug, Nile Flyer (eventually released as Desert Falcon), Robotron: 2084, Galaga, Food Fight, Ballblazer, Rescue on Fractalus! (later canceled),{{cite web |last=Reichert |first=Matt |title = Rescue on Fractalus |website=AtariProtos.com |url=http://www.atariprotos.com/7800/software/rof/rof.htm |access-date = 2023-10-12}} Track & Field, and Xevious. It was a significant technological leap over the Atari 2600 and Atari 5200.

On July 2, 1984, Warner Communications sold Atari's Consumer Division to Jack Tramiel.[Retrogamer Magazine, Issue #78, pp 53.] All projects were halted during an initial evaluation period. GCC had not been paid for their development of the 7800, and Warner and Tramiel fought over who was accountable. In May 1985, Tramiel relented and paid GCC. This led to additional negotiations regarding the launch titles GCC had developed, then an effort to find someone to lead their new video game division, which was completed in November 1985.[Retrogamer Magazine, Issue #78, pp 57] The original production run of the Atari 7800 languished in warehouses until it was introduced in January 1986.

The console was released nationwide in May 1986 for $79.95{{Cite news|title=Atari's "Jr Pac-Man" scores for looks, sound|last=Semrad|first=Edward|date=1986-06-26|work=The Milwaukee Journal}} with games intended for the 7800's debut in 1984.{{Citation|title=Atari 7800 - History of Video Game Consoles Wiki Guide - IGN|date=27 March 2014 |url=https://www.ign.com/wikis/history-of-video-game-consoles/Atari_7800|language=en|access-date=2019-01-23}} It was aided by a marketing campaign with a budget in the "low millions" according to Atari Corporation officials. This was substantially less than the $9 million spent by Sega and the $16 million spent by Nintendo.[blob:https://imgur.com/5e89e610-0413-45b3-90cc-a9c05e8e21b5]{{dead link|date=September 2021}}, Detroit Press, August 15th, 1986 The keyboard and high score cartridge planned by Warner were cancelled. The 7800 addressed many of the most common complaints with the preceding 5200, including a smaller size, built-in backward compatibility, and an improved controller design.

In February 1987, Computer Entertainer reported that 100,000 Atari 7800 consoles had been sold in the United States, including those which had been warehoused since 1984.Computer Entertainer, February 1987, [http://i.imgur.com/eUXac6M.jpg page 13]Computer Entertainer, December 1986, [http://i.imgur.com/fyarkYE.jpg page 8] This was less than the Master System's 125,000 and the NES's 1.1 million. Games were slowly released: Galaga in August, followed by Xevious in November. By the end of 1986, the 7800 had 10 games, compared to Sega's 20 and Nintendo's 36. Atari would sell over 1 million 7800 consoles by June 1988.{{cite web |url=https://atariage.com/forums/uploads/monthly_01_2008/post-9346-1201143700.jpg | title=Axlon to develop new video games for Atari; Bushnell returns}}

On January 1, 1992, Atari Corporation announced the end of production and support for the 7800, 2600, and the 8-bit computer family including the Atari XEGS. At least one game, an unreleased port of Toki, was worked on past this date.{{cite web|url=http://betaphasegames.com/7800_Toki_Screens.html |title=TOKI FOR 7800: DISCOVERY ANNOUNCEMENT |website=Beta Phase Games|archive-url=https://web.archive.org/web/20180418231623/http://betaphasegames.com/7800_Toki_Screens.html |archive-date=2018-04-18 }} By the time of the discontinuation, the Nintendo Entertainment System controlled 80% of the North American market while Atari had 12%.{{cite news| url=https://query.nytimes.com/gst/fullpage.html?res=9E0CE3DD143EF935A25756C0A964958260 | work=The New York Times | title=COMPANY NEWS; Nintendo Suit by Atari Is Dismissed | date=May 16, 1992 | access-date=April 25, 2010 |url-access=limited}} In Europe, last stocks of the 7800 were sold until summer/fall of 1995.{{cite web | url=https://atarimuseum.nl/history-of-atari-benelux/ | title=Atari Benelux Timeline – Atarimuseum.nl }}

Retro Gamer magazine issue 132 reported that according to Atari UK Marketing Manager Darryl Still, "it was very well stocked by European retail; although it never got the consumer traction that the 2600 did, I remember we used to sell a lot of units through mail order catalogues and in the less affluent areas".{{cite web |title=Atari 7800 Prosystem 30th Anniversary |date=10 September 2016 |url=https://issuu.com/michelfranca/docs/retro_gamer____132 |publisher=Retro Gamer |access-date=18 August 2018}}

Graphics are generated by the custom MARIA chip, which uses an approach common in contemporary arcade system boards and is different from other second and third generation consoles. Instead of a limited number of hardware sprites, MARIA treats everything as a sprite described in a series of display lists. Each display list contains pointers to graphics data and color and positioning information.

MARIA supports a palette of 256 colors and graphics modes which are either 160 pixels wide or 320 pixels wide. While the 320 pixel modes theoretically enable the 7800 to create games at higher resolution than the 256 pixel wide graphics found in the Nintendo Entertainment System and Master System, the processing demands of MARIA result in most games using the 160 pixel mode.{{citation needed|date=March 2014}}

Each sprite can have from 1 to 12 colors, with 3 colors plus transparency being the most common. In this format, the sprite references one of 8 palettes, where each palette holds 3 colors. The background (visible when not covered by other objects) can also be assigned a color. In total, 25 colors can appear on a scan line.

The graphics resolution, color palettes, and background color can be adjusted between scan lines.{{cite web |title=Atari 3600 Software Guide |url=http://www.atarimuseum.com/ahs_archives/archives/pdf/videogames/7800/3600_software_guide.pdf |archive-url=https://web.archive.org/web/20101207033819/http://www.atarimuseum.com/ahs_archives/archives/pdf/videogames/7800/3600_software_guide.pdf |archive-date=2010-12-07 }}

The 7800 uses the TIA chip for two channel audio, the same chip used in the 1977 Atari VCS, and the sound is of the same quality as that system. To compensate, GCC's engineers allowed games to include a POKEY audio chip in the cartridge. Only Ballblazer and Commando do this.

GCC planned to make a low-cost, high performance sound chip, GUMBY, which could also be placed in 7800 cartridges to enhance its sound capabilities further.{{Cite web |title=The 7800 Minnie sound chip - 8BitDev.org - Atari 7800 Development Wiki |url=https://7800.8bitdev.org/index.php/The_7800_Minnie_sound_chip |access-date=2024-03-02 |website=7800.8bitdev.org}} This project was cancelled when Atari was sold to Jack Tramiel.

Following the large number of low quality, third party games for the Atari 2600, Atari required that cartridges for the 7800 be digitally signed. When a cartridge is inserted into the system, the BIOS generates a signature of the cartridge ROM and compares it to the one stored on the cartridge. If they match, the console operates in 7800 mode, granting the game access to MARIA and other features, otherwise the console operates as a 2600. This digital signature code is not present in PAL 7800s, which use various heuristics to detect 2600 cartridges, due to export restrictions.

The 7800's compatibility with the Atari 2600 is made possible by including many of the same chips used in the 2600. When playing an Atari 2600 game, the 7800 uses a Television Interface Adaptor chip to generate graphics and sound. The processor is slowed to 1.19 MHz, to mirror the performance of the 2600's 6507 chip. RAM is limited to 128 bytes and cartridge data is accessed in 4K blocks.

When in 7800 mode (signified by the appearance of the full-screen Atari logo), the graphics are generated entirely by the MARIA graphics processing unit. All system RAM is available and cartridge data is accessed in larger 48K blocks. The system's SALLY 6502 runs at its normal 1.79 MHz. The 2600 chips are used to generate sound and to provide the interfaces to the controllers and console switches.

The Atari 7800 came bundled with the Atari Pro-Line Joystick, a two-button controller with a joystick for movement. The Pro-Line was developed for the 2600 and advertised in 1983,{{cite web |title=Catalog - Atari (CO21776-Rev. A) |url=https://atariage.com/catalog_thumbs.php?CatalogID=38 |website=AtariAge }} but delayed until Atari proceeded with the 7800. The right fire button only works as a separate fire button for certain 7800 games; otherwise, it duplicates the left fire button, allowing either button to be used for 2600 games. While physically compatible, the 7800's controllers do not work with the Sega Master System, and Sega's controllers are unable to use the 7800's two-button mode.

In response to criticism over ergonomic issues with the Pro-Line controllers, Atari later released a joypad controller with the European 7800.{{Cite book|title=The Game Machines|pages=138}} Similar in style to controllers found on Nintendo and Sega systems, it was not available in the United States.

The Atari XG-1 light gun, bundled with the Atari XEGS and also sold separately, is compatible with the 7800. Atari released five 7800 light gun games: Alien Brigade, Barnyard Blaster, Crossbow, Meltdown, and Sentinel.

After the acquisition of the Atari Consumer Division by Jack Tramiel in 1984, several expansion options for the system were cancelled:

• The High Score Cartridge was designed to save high scores for up to 65 separate games.{{cite book |url=https://books.google.com/books?id=-8YlaRclj2gC&dq=The+High+Score+Cartridge+was+designed+to+save+high+scores+for+up+to+65+separate+games&pg=PA139 |title=The Games Machine |page=139 |date=December 2019}} The cartridge was intended as a pass-through device, similar to the later Game Genie. Nine games were programmed to support the cartridge.
• The expansion port, to allow for the addition of a planned computer keyboard and connection to laserdisc players and other peripherals, was removed in the second and third revisions of the 7800.{{Cite web|url=https://www.ataricompendium.com/game_library/easter_eggs/7800/78prosystem.html|title=Atari Compendium|website=www.ataricompendium.com|accessdate=16 February 2024}}

While the system can play the over 400 games for the Atari 2600, there were only 59 official releases for the 7800. The lineup emphasized high-quality versions of games from the golden age of arcade video games.{{cite magazine | title=Video Gaming World | magazine=Computer Gaming World | issue=50 | date=August 1988 | url=http://www.cgwmuseum.org/galleries/issues/cgw_50.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.cgwmuseum.org/galleries/issues/cgw_50.pdf |archive-date=2022-10-09 |url-status=live | access-date=17 April 2016 | last1=Katz | first1=Arnie | last2=Kunkel | first2=Bill | last3=Worley | first3=Joyce | pages=47}} Pole Position II, Dig Dug, and Galaga, by the time of the 1986 launch, were three, four, and five years old, respectively. A raster graphics version of 1979's Asteroids was released in 1987. In 1988, Atari published a conversion of Nintendo's Donkey Kong, seven years after the original arcade game and five years after the Atari 8-bit computer cartridge. Atari also marketed a line of games called "Super Games" which were arcade and computer games previously not playable on a home console such as One-On-One Basketball and Impossible Mission.[http://www.tankgirl.info/8bit/images/atari/7800/boxBottom.jpg Image] tankgirl.info

Eleven games were developed and sold by three third-party companies under their own labels (Absolute Entertainment, Activision, and Froggo) with the rest published by Atari Corporation. Most of the games from Atari were developed by outside companies under contract.{{cite web|last1=Jung|first1=Robert A.|title=The Atari Timeline|url=https://www.landley.net/history/mirror/atari/museum/Atari-Timeline.html|website=Landley|access-date=13 February 2017}}

Some NES games were developed by companies who had licensed their title from a different arcade manufacturer. While the creator of the NES version would be restricted from making a competitive version of an NES game, the original arcade copyright holder was not precluded from licensing out rights for a home version of an arcade game to multiple systems. Through this loophole, Atari 7800 conversions of Mario Bros., Double Dragon, Commando, Rampage, Xenophobe, Ikari Warriors, and Kung-Fu Master were licensed and developed.{{citation needed|date=March 2014}}

A final batch of games was released by Atari in 1990: Alien Brigade, Basketbrawl, Fatal Run, Meltdown, Midnight Mutants, MotorPsycho, Ninja Golf, Planet Smashers, and Scrapyard Dog. Scrapyard Dog was later released for the Atari Lynx.

In 2004, the Infogrames-owned version of Atari released the Atari Flashback console. It resembles a miniature Atari 7800 and has five 7800 and fifteen 2600 games built-in. Built using the NES-On-A-Chip hardware instead of recreating the Atari 7800 hardware, it was criticized for failing to properly replicate the actual gaming experience. A subsequent 7800 project was cancelled after prototypes were made.{{cite web|url=http://www.legacyengineer.com/portfolio-7800.html |title=Remake of the Atari 7800 console |access-date=2010-12-22 |url-status=dead |archive-url=https://web.archive.org/web/20110311035331/http://www.legacyengineer.com/portfolio-7800.html |archive-date=2011-03-11 }} Legacy 7800 remade
