105-536: The Coleco Gemini is an Atari 2600 clone manufactured by Coleco Industries, Inc. in 1983. In 1982, Coleco released Expansion Module #1 for its ColecoVision video game system. With a custom-made clone of the Atari 2600 TIA chip and off-the-shelf components, the module enabled the ColecoVision to be compatible with Atari 2600 software. Later that year, Atari, Inc. sued Coleco for patent infringement , and

210-734: A Ctrl + Alt + Reset keypress sequence—a hard reset which discards any information currently in RAM . Several oscilloscopes contain Easter eggs. One example is the HP ;54600B , known to have a Tetris (1985) clone, and the HP 54622D contains an imitation of the Asteroids (1979) game named Rocks . Another is the Tektronix 1755A Vector and Waveform Monitor which displays swimming fish when Remote > Software version

315-476: A $ 425 million loss reported in the second quarter. By mid-1984, software development for the 2600 had essentially stopped except that of Atari and Activision. Warner, wary of supporting its failing Atari division, started looking for buyers in 1984. Warner sold most of the assets of Atari's counsumer electronics and home computer divisions to Jack Tramiel , the founder of Commodore International , in July 1984 in

420-517: A mainframe computer . Therefore, development of a console had cost at least $ 100,000 (equivalent to about $ 566,000 in 2023) plus time to complete, but the final product only had about a three-month shelf life until becoming outdated by competition. By 1974, Atari had acquired Cyan Engineering , a Grass Valley electronics company founded by Steve Mayer and Larry Emmons, both former colleagues of Bushnell and Dabney from Ampex , who helped to develop new ideas for Atari's arcade games. Even prior to

525-469: A pinball game in Microsoft Word . Since 2002, Microsoft does not allow any hidden or undocumented code as part of its trustworthy computing initiative. The Debian operating system's package tool apt-get has an Easter egg involving an ASCII cow when variants on apt-get moo are typed into the shell. An Easter egg is found on all Microsoft Windows operating systems before XP . In

630-734: A " logic bomb " could also bypass testing. Kabay asserts that this undermined the Trusted Computing Base , a paradigm of trustworthy hardware and software in place since the 1980s, and is of concern wherever personal or confidential information is stored, as this may then be vulnerable to damage or manipulation. Microsoft created some of the largest and most elaborate Easter eggs, such as those in Microsoft Office . In 2005, Larry Osterman of Microsoft acknowledged Microsoft Easter eggs, and his involvement in development of one, but described them as "irresponsible", and wrote that

735-690: A 2600, though companies like Epoch had distributed the 2600 in Japan previously. The 2800 was released a short time after Nintendo 's Family Computer (which became the dominant console in Japan), and it did not gain a significant share of the market. Sears previously released the 2800 in the US during late 1982 as the Sears Video Arcade II, which came packaged with two controllers and Space Invaders . Around 30 specially branded games were released for

840-500: A 50  Hz format, is limited to 8 colors, each with only a single brightness level. The first VCS bundle has two types of controllers: a joystick (part number CX10) and pair of rotary paddle controllers (CX30). Driving controllers, which are similar to paddle controllers but can be continuously rotated, shipped with the Indy 500 launch game. After less than a year, the CX10 joystick

945-601: A November 1983 article in InfoWorld magazine. An August 1984 InfoWorld magazine article says more than 15 million Atari 2600 machines were sold by 1982. A March 1983 article in IEEE Spectrum magazine has about 3 million VCS sales in 1981, about 5.5 million in 1982, as well as a total of over 12 million VCS systems and an estimated 120 million cartridges sold. In Europe, the Atari VCS sold 125,000 units in

1050-543: A character named Loo-Kee who typically appeared once per episode, hidden in a single screenshot. At the end of the episode, the screenshot would be shown again and Loo-Kee would challenge viewers to locate him before revealing his hiding place. Adventure Time also had a character known as The Snail that was hidden in almost every episode of the show. More recent broadcast media, where viewers have access to high-resolution digital copies or streaming services, may include further Easter eggs that can only be found by freezing

1155-640: A character's room. Similarly, a programmer included the whole of TimeSplitters 2 (2002) within Homefront: The Revolution (2016), accessed by using a special code at an in-game arcade cabinet. Other Easter eggs originated unintentionally. The Konami Code , a type of cheat code , became an intentional Easter egg in most games, but it originated from Konami's Gradius (1985) for the Nintendo Entertainment System . The programmer, Kazuhisa Hashimoto , created

1260-469: A deal valued at $ 240 million , though Warner retained Atari's arcade business. Tramiel was a proponent of personal computers , and halted all new 2600 game development soon after the sale. The North American video game market did not recover until about 1986, after Nintendo 's 1985 launch of the Nintendo Entertainment System in North America. Atari Corporation released a redesigned model of

1365-443: A game console, and offered to discuss it further at Cyan's facilities after the show. Over two days, MOS and Cyan engineers sketched out a 6502-based console design by Meyer and Milner's specifications. Financial models showed that even at $ 25 , the 6502 would be too expensive, and Peddle offered them a planned 6507 microprocessor , a cost-reduced version of the 6502, and MOS's RIOT chip for input/output . Cyan and MOS negotiated

1470-601: A hidden action game similar to Doom (1993) called The Hall of Tortured Souls . The Google search engine famously contains many Easter eggs , given to the user in response to certain search queries. Steve Jobs banned Easter eggs from Apple products upon his return to the company. The first Easter egg to appear after his death is in a 2012 update to the Mac App Store for OS X Mountain Lion , in which downloaded apps are temporarily timestamped as "24 January 1984",

1575-525: A home console. Atari sold 1.25 million Space Invaders cartridges and over 1 million VCS systems in 1980, nearly doubling the install base to over 2 million, and then an estimated 3.1 million VCS systems in 1981. By 1982, 10 million consoles had been sold in the United States, while its best-selling game was Pac-Man at over 8 million copies sold by 1990. Pac-Man propelled worldwide Atari VCS sales to 12 million units during 1982, according to

1680-537: A landfill in the New Mexico desert, later labeled the Atari video game burial . Long considered an urban legend that claimed the burial contained millions of unsold cartridges, the site was excavated in 2014, confirming reports from former Atari executives that only about 700,000 cartridges had actually been buried. Atari reported a $ 536 million loss for 1983 as a whole, and continued to lose money into 1984, with

1785-479: A living room environment". Landrum recommended it include four to five dedicated games in addition to the cartridges, but this was dropped in the final designs. The cartridge design was done by James Asher and Douglas Hardy. Hardy had been an engineer for Fairchild and helped in the initial design of the Channel F cartridges, but he quit to join Atari in 1976. The interior of the cartridge that Asher and Hardy designed

1890-675: A native controller. Third-party controllers include Wico's Command Control joystick. Later, the CX42 Remote Control Joysticks, similar in appearance but using wireless technology, were released, together with a receiver whose wires could be inserted in the controller jacks. Atari introduced the CX50 Keyboard Controller in June 1978 along with two games that require it: Codebreaker and Hunt & Score . The similar, but simpler, CX23 Kid's Controller

1995-440: A perceived slight. Easter eggs in video games take a variety of forms, from purely ornamental screens to aesthetic enhancements that change some element of the game during play. The Easter egg included in the original Age of Empires (1997) is an example of the latter; catapult projectiles are changed from stones to cows. More elaborate Easter eggs include secret levels and developers' rooms—fully functional, hidden areas of

2100-628: A player. Atari's management initially wanted to remove the message and release the game again, until this was deemed too costly. Instead, Steve Wright, the Director of Software Development in the Atari Consumer Division, suggested that they keep the message and, in fact, encourage the inclusion of such messages in future games, describing them as Easter eggs for consumers to find. While Robinett's message in Adventure led to

2205-560: A reference to the Monty Python Dirty Hungarian Phrasebook skit; " exit %xb70 " returns the message "%SYSTEM-W-FISH, my hovercraft is full of eels" while " exit %x34b4 " returns a reference to an early Internet meme : "%SYSTEM-F-GAMEOVER, All your base are belong to us ". Easter eggs in the 1997 version of Microsoft Office include a hidden flight simulator in Microsoft Excel and

2310-550: A result of introducing programming tricks to get around some of the difficulty they had in getting Sega's strict certification for their games, catching any exceptions during execution to bring the game back to a usable state as to pass certification. For example, hitting the side of the Sonic 3D Blast (1996) cartridge while it is slotted in the console will bring the game back to the Level Select screen, which Burton explains

2415-510: Is "another signifier of artistry in the world of DVD supplements." According to American film critics James Berardinelli and Roger Ebert , most DVDs do not contain them and most examples are "inconsequential", but a few, such as the one found on the Memento DVD release, are "worth the effort to seek out". Unlike DVDs and computer games, broadcast radio and television programs contain no executable code. Easter eggs may still appear in

2520-649: Is commonly referred to by fans as the "Vader" model, due to its resemblance to the Star Wars character of the same name. Atari continued its OEM relationship with Sears under the latter's Tele-Games brand, which started in 1975 with the original Pong . This is unrelated to the company Telegames , which later produced 2600 cartridges. Sears released several models of the VCS as the Sears Video Arcade series starting in 1977. The final Sears-specific model

2625-605: Is selected on the CONFIG menu. In the second and third hardware revision of the Minolta Dynax/Maxxum/Alpha 9 (introduced in 1998) SLR camera, including all SSM/ADI upgraded bodies (since 2003), an undocumented button sequence can be utilized to reconfigure the camera to behave like the Dynax/Maxxum/Alpha 9Ti (1999) and subsequently invoke support for the limited model's extra functions also in

2730-744: Is the pro controller for the Nintendo Switch , on the controller's motherboard , if a player holds down on the right stick and looks closely into the transparent plastic surrounding its socket while shining a light on it, there is a hidden message that reads "THX2ALLGAMEFANS!". The message was discovered by Japanese Twitter user Geo Stream on March 4, 2017, one day after the Switch's launch. American comic book artists are known to include hidden messages in their art: Easter eggs are found on films, DVDs , and Blu-ray Discs , often as deleted scenes or bonus features. Klinger states that their presence

2835-465: Is the default exception handling for any unidentified processor error, such as when connectivity between the cartridge and the console's microprocessor is temporarily lost. In computer software , Easter eggs are secret responses that occur as a result of an undocumented set of commands. The results can vary from a simple printed message or image to a page of programmer credits or a small video game hidden inside an otherwise serious piece of software. In

2940-663: The Atari Video Computer System ( Atari VCS ), 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 cartridge—initially Combat and later Pac-Man . Sears sold the system as the Tele-Games Video Arcade . Atari rebranded

3045-482: The Kee Games label and include changes to the hardware that make the game appear different from the Atari version. Anti-Aircraft II (1975) includes a means to modify the circuit board to make the airplanes in the game appear as alien UFOs. Fries surmises that this feature may have been intended for a Kee Games release. For this reason, and because it requires a hardware modification, Fries questions whether it meets

3150-649: The TOPS-10 operating system (for the DEC PDP-10 mainframe computer ), the make command is used to invoke the TECO editor to create a file. If given the file name argument love , so that the command reads make love , it will pause and respond not war? before creating the file. The Easter egg was added sometime between October 1967 and October 1968 by William F. Weiher at the Stanford AI Lab to

3255-428: The call stack , and the state of the game environment. The top bezel of the console originally had six switches: power, TV type selection (color or black-and-white), game selection, left and right player difficulty, and game reset. The difficulty switches were moved to the back of the bezel in later versions of the console. The back bezel also included the controller ports, TV output, and power input. The Atari 2600

Many integrated circuit (chip) designers have included hidden graphics elements termed chip art , including images, phrases, developer initials, logos, and more. This artwork, like the rest of the chip, is reproduced in each copy by lithography and etching . These are visible only when

3465-461: The 1980 video game Adventure for the Atari 2600 game console, programmed by the employee Warren Robinett . At the time, Atari did not include programmers' names in the game credits, both to prevent competitors from poaching its developers as well as to deny developers a means to bargain with the management of the new owners, Warner Communications . Robinett, who disagreed with his supervisor over this lack of acknowledgment, secretly programmed

3570-471: The 2600 in 1986, supported by an ad campaign touting a price of "under 50 bucks". With a large library of cartridges and a low price point, the 2600 continued to sell into the late 1980s. Atari released the last batch of games in 1989–90 including Secret Quest and Fatal Run . By 1986, over 20 million Atari VCS units had been sold worldwide. The final Atari-licensed release is the PAL-only version of

3675-461: The 2600 was supported with new games and television commercials promoting "The fun is back!". Atari released several minor stylistic variations: the "large rainbow" (shown), "short rainbow", and an all-black version sold only in Ireland. Later European versions include a joypad. The Atari 2700 was a version of the 2600 with wireless controllers. The CX2000, with integrated joystick controllers,

3780-451: The 2600. Mattel used the M Network brand name for its cartridges. Third-party games accounted for half of VCS game sales by 1982. In addition to third-party game development, Atari also received the first major threat to its hardware dominance from the ColecoVision. Coleco had a license from Nintendo to develop a version of the arcade game Donkey Kong (1981), which was bundled with every ColecoVision console. Coleco gained about 17% of

3885-413: The 2800. Designed by engineer Joe Tilly, the 2800 has four controller ports instead of the two of the 2600. The controllers are an all-in one design using a combination of an 8-direction digital joystick and a 270-degree paddle , designed by John Amber. The 2800's case design departed from the 2600, using a wedge shape with non-protruding switches. The case style is the basis for the Atari 7800 , which

3990-550: The 3D Text screen saver , entering the text "volcano" will display the names of all the volcanoes in the United States. Microsoft removed this Easter egg in XP but added others. In Windows Vista and later, by launching a screensaver executable (introduced with Windows Vista) on the command line with the /p65552 flag, for example launching the "bubbles" screen saver with bubbles.scr /p65552 command-line parameter, it runs as desktop wallpaper . Microsoft Excel 95 contains

4095-542: The 6507 and RIOT chips at $ 12 a pair. MOS also introduced Cyan to Microcomputer Associates , who had separately developed debugging software and hardware for MOS, and had developed the JOLT Computer for testing the 6502, which Peddle suggested would be useful for Atari and Cyan to use while developing their system. Milner was able to demonstrate a proof-of-concept for a programmable console by implementing Tank , an arcade game by Atari's subsidiary Kee Games , on

4200-459: The 6507, the TIA, and other components, so the programmers creatively optimized their games to maximize the console. The console lacks a framebuffer and requires games to instruct the system to generate graphics in synchronization with the electron gun in the cathode-ray tube (CRT) as it scans across rows on the screen. The programmers found ways to " race the beam " to perform other functions while

4305-809: The COMPIL program for the PDP-6, which was then used in the TOPS-10 operating system, making it the first Easter egg in a software program. This same behavior occurs on the RSTS/E operating system, where TECO will provide this response. Other Unix operating systems respond to " why " with " why not " (a reference to The Prisoner in Berkeley Unix , 1977). Some versions of the DEC OpenVMS operating system have concealed exit status codes, including

4410-535: The Extra-Terrestrial , a game programmed in about six weeks. Atari produced an estimated four million cartridges, but the game was poorly reviewed, and only about 1.5 million units were sold. Warner Communications issued revised earnings guidance in December 1982 to its shareholders, having expected a 50% year-to-year growth but now only expecting 10–15% due to declining sales at Atari. Coupled with

4515-471: The JOLT. As part of the deal, Atari wanted a second source of the chipset. Peddle and Paivinen suggested Synertek whose co-founder, Bob Schreiner, was a friend of Peddle. In October 1975, Atari informed the market that it was moving forward with MOS. The Motorola sales team had already told its management that the Atari deal was finalized, and Motorola management was livid. They announced a lawsuit against MOS

4620-548: The United Kingdom during 1980, and 450,000 in West Germany by 1984. In France, where the VCS released in 1982, the system sold 600,000 units by 1989. The console was distributed by Epoch Co. in Japan in 1979 under the name "Cassette TV Game", but did not sell as well as Epoch's own Cassette Vision system in 1981. In 1982, Atari launched its second programmable console, the Atari 5200 . To standardize naming,

4725-528: The VCS as the Atari 2600 in November 1982, alongside the release of the Atari 5200 . 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 under the codename Stella by Atari subsidiary Cyan Engineering . Lacking funding to complete

4830-503: The VCS was made in Sunnyvale during 1977, using thick polystyrene plastic for the casing as to give the impression of weight from what was mostly an empty shell inside. The initial Sunnyvale batch had also included potential mounts for an internal speaker system on the casing, though the speakers were found to be too expensive to include and instead sound was routed through the TIA to the connected television. All six console switches on

4935-660: The VCS was renamed to the "Atari 2600 Video Computer System", or "Atari 2600", derived from the manufacture part number CX2600. By 1982, the 2600 cost Atari about $ 40 to make and was sold for an average of $ 125 (equivalent to $ 390 in 2023). The company spent $ 4 .50 to $ 6 to manufacture each cartridge, plus $ 1 to $ 2 for advertising, wholesaling for $ 18.95 (equivalent to $ 60 in 2023). Activision , formed by Crane, Whitehead, and Miller in 1979, started developing third-party VCS games using their knowledge of VCS design and programming tricks, and began releasing games in 1980. Kaboom! (1981) and Pitfall! (1982) are among

5040-439: The VCS would render the console obsolete. However, the board stayed committed to the VCS and ignored Bushnell's advice, leading to his departure from Atari in 1979. Atari sold about 600,000 VCS systems in 1979, bringing the installed base to a little over 1.3 million. Atari obtained a license from Taito to develop a VCS conversion of its 1978 arcade hit Space Invaders . This is the first officially licensed arcade conversion for

5145-469: The arcade game KLAX in 1990. After more than 14 years on the market, 2600 production ended in 1992, along with the Atari 7800 and Atari 8-bit computers . In Europe, last stocks of the 2600 were sold until Summer/Fall of 1995. The Atari 2600's CPU is the MOS Technology 6507 , a version of the 6502 , running at 1.19 MHz in the 2600. Though their internal silicon was identical, the 6507

5250-512: The astronaut will visit it instead of standing next to the ship. The earliest known Easter egg in software in general is one placed in the "make" command for PDP-6 / PDP-10 computers sometime in October 1967–October 1968, wherein if the user attempts to create a file named "love" by typing "make love", the program responds " not war? " before proceeding. The use of the term " Easter egg " to describe secret features in video games originates from

5355-525: The basis for the Magnavox Odyssey . In mid-1976, Fairchild announced the Channel F, planned for release later that year, beating Atari to the market. By October 1976, Warner and Atari agreed to the purchase of Atari for $ 28 million . Warner provided an estimated $ 120 million which was enough to fast-track Stella. By 1977, development had advanced enough to brand it the "Atari Video Computer System" (VCS) and start developing games. The unit

5460-553: The black areas around the screen to extend the game code's processing time. Regional releases of the Atari 2600 use modified TIA chips for each region's television formats, which require games to be developed and published separately for each region. All modes are 160 pixels wide. NTSC mode provides 192 visible lines per screen, drawn at 60  Hz , with 16 colors, each at 8 levels of brightness. PAL mode provides more vertical scanlines, with 228 visible lines per screen, but drawn at 50 Hz and only 13 colors. SECAM mode, also

5565-578: The black model. One of HP's electronic pocket calculators , the HP-45 (introduced in 1973), has a built-in undocumented stopwatch . The firmware of HP's ScanJet 5p image scanner contains an easter egg wherein, on a cold power-on, holding down the scan button when the SCSI ID selector on the back is set to "0" will cause the ScanJet to play a rendition of Schiller 's " Ode to Joy ", by modulating

5670-402: The bottom of the controller). To play paddle games on the 2600, a Y-connector could be used to connect a joystick and paddles to the controller jack at the same time, rather than physically swapping controllers. The Gemini was more compact than the large faux- woodgrain or gloss black-trimmed consoles sold by Atari at the time. The Gemini also had a different game included with the system. Atari

5775-481: The cabinet's controls in the right order, the player can have the message "Hi Ron!" appear on the screen. Fries describes it as "the earliest arcade game yet known that clearly meets the definition of an Easter egg". The existence of this Easter egg was not published until 2017, leading Fries to suggest that, as more than one hundred arcade games predate Starship 1 , earlier Easter eggs may still be undiscovered. Fries says that some Atari arcade cabinets were resold under

5880-693: The chip package is opened and examined under magnification. The 1984 CVAX microchip implementation of the MicroVAX CPU contains in its etchings the Russian phrase in the Cyrillic alphabet "VAX: When you care enough to steal the very best", placed there because, "knowing that some CVAXs would end up in the USSR, the team wanted the Russians to know that we were thinking of them". Another notable example

5985-639: The code as a means to rapidly debug the game by giving the player's avatar additional health and powers to easily traverse the game. These types of codes are normally removed from the game before it is shipped but, in the case of Gradius , Hashimoto forgot to remove it and the code was soon discovered by players. Its popularity inspired Konami to reuse the code and purposely retain it for many of its future games as an Easter egg. Technical issues may also create unintentional Easter eggs. Jon Burton , founder of Traveller's Tales , said that many seemingly apparent Easter eggs in their Sega Genesis games came about as

6090-439: The code to the screen on the part of the programmer was labeled " racing the beam "; the actual game logic runs when the television beam is outside of the visible area of the screen. Early games for the system use the same visuals for pairs of scan lines, giving a lower vertical resolution, to allow more time for the next row of graphics to be prepared. Later games, such as Pitfall! , change the visuals for each scan line or extend

6195-463: The companies wound up settling out of court, with Coleco becoming a licensee of Atari's patents . The main difference between the Coleco Gemini and the Atari 2600 is the controller design. The Coleco Gemini controllers (dubbed the 'Dual Command') featured an 8-way joystick and a 270- degree paddle on the same controller (the joystick was at the top of the controller, and the paddle was at

6300-641: The company's Operating System division "has a 'no Easter Eggs' policy" as part of its Trustworthy Computing initiative. In 2006, Douglas W. Jones said that while "some Easter eggs may be intentional tools used to detect illegal copying , others are clearly examples of unauthorized functionality that has slipped through the quality-control tests at the vendor". While hidden Easter eggs themselves are harmless, it may be possible for malware to be hidden in similar ways in voting machines or other computers. Netscape Navigator contributor Jamie Zawinski stated in an interview in 1998 that harmless Easter eggs impose

6405-435: The content itself, such as a hidden Mickey in a Disney film or a real telephone number instead of a 555 fictitious telephone number . A 2014 Super Bowl advertisement was leaked online in which a lady gives a man a real telephone number, which the advertiser had hidden as a marketing ploy; the first caller to the number received a pair of tickets to the game.

6510-519: The date of the sales launch of the original Macintosh . The Python programming language and its ecosystem of libraries include various Easter eggs. While computer-related Easter eggs are often found in installed software , occasionally they exist in the firmware of certain devices. On some home and early personal computers the ROM contains Easter eggs, including lists of the developers' names, political exhortations, snatches of music, or images of

6615-488: The definition of an Easter egg. In 2004, an Easter egg displaying programmer Bradley Reid-Selth's surname was found in Video Whizball (1978), a game for the Fairchild Channel F system. Since Adventure , there has been a long history of video game developers placing Easter eggs in their games. Most Easter eggs are intentional—an attempt to communicate with the player or a way of getting even with management for

6720-486: The delay in shipping the units and consumers' unfamiliarity with a swappable-cartridge console that is not dedicated to only one game. In 1978, Atari sold only 550,000 of the 800,000 systems manufactured. This required further financial support from Warner to cover losses. Bushnell pushed the Warner Board of Directors to start working on "Stella 2", as he grew concerned that rising competition and aging tech specs of

6825-592: The development team in the ROM. These Mac Easter eggs were well-publicized in the Macintosh press at the time along with the means to access them, and were later recovered by an NYC Resistor team, a hacker collective , through elaborate reverse engineering . Similarly, the Radio Shack Color Computer ;3 's ROM contains code which displays what looks like three Microware developers on

6930-571: The electron gun scans outside of the visible screen. Alongside the electronics development, Bushnell brought in Gene Landrum, a consultant who had just prior consulted for Fairchild Camera and Instrument for its upcoming Channel F , to determine the consumer requirements for the console. In his final report, Landrum suggested a living room aesthetic, with a wood grain finish, and the cartridges must be "idiot proof, child proof and effective in resisting potential static [electricity] problems in

The built-in maze game "Lair of Squid" incorporates a hidden gallery of the software developers. In test mode it displays several poems. Other notable examples include some versions of the AMI BIOS that on 13 November 1993, proceeded to play "Happy Birthday" via the PC speaker repeatedly instead of booting , as well as several early Apple Macintosh models that have photos of

7140-481: The first text adventure game, Colossal Cave Adventure (1976), from which Adventure was fashioned, which includes several secret words. One of these is " xyzzy ", a command which enables the player to move between two points in the game world. According to research by Ed Fries , one of the earliest Easter eggs in a graphical video games could be found in Starship 1 (1977), programmed by Ron Milner. By triggering

7245-557: The first use of the phrase "Easter egg", Easter eggs were included in previous video games. The earliest known video game Easter egg is in Moonlander (1973), in which the player tries to land a spaceship on the Moon. If the player flies far enough horizontally, they encounter a McDonald's restaurant, and if they land next to it, an astronaut will visit it instead of standing next to the ship. Other early known Easter eggs include one in

7350-438: The front and replacing the previous all lowercase font for the switch labels to fully capitalized wording. Otherwise, these four-switch consoles look nearly identical to the earlier six-switch models. In 1982, to coincide with the release of the Atari 5200, Atari rebranded the console as the "Atari 2600", a name first used on a version of the four-switch model without woodgrain, giving it an all-black appearance. This all-black model

7455-428: The front panel. Production of the unit was moved to Taiwan in 1978, where a less thick internal metal shielding was used and thinner plastic was used for the casing, reducing the system's weight. These two versions are commonly referred to as "Heavy Sixers" and "Light Sixers" respectively, referencing the six front switches. In 1980, the difficulty switches were moved to the back of the console, leaving four switches on

7560-519: The game. Developers' rooms often include inside jokes from the fandom or development team and differ from a debug room in that they are specifically intended for the player to find. Some games even include hidden minigames as Easter eggs. In the LucasArts game Day of the Tentacle (1993), the original Maniac Mansion (1987) game can be played in its full version by using a home computer in

7665-446: The hardware market in 1982 compared to Atari's 58%. With third parties competing for market share, Atari worked to maintain dominance in the market by acquiring licenses for popular arcade games and other properties to make games from. Pac-Man has numerous technical and aesthetic flaws, but nevertheless more than 7 million copies were sold. Heading into the 1982 holiday shopping season, Atari had placed high sales expectations on E.T.

7770-522: The licensing model that continues to be used by console manufacturers for game development. Activision's success led to the establishment of other third-party VCS game developers following Activision's model in the early 1980s, including U.S. Games , Telesys , Games by Apollo , Data Age , Zimag , Mystique , and CommaVid . The founding of Imagic included ex-Atari programmers. Mattel and Coleco, each already producing its own more advanced console, created simplified versions of their existing games for

7875-439: The message "Created by Warren Robinett" to appear only if a player moves their avatar over a specific pixel (dubbed the "Gray Dot") during a certain part of the game and enters a previously "forbidden" part of the map where the message can be found. When Robinett left Atari, he did not inform the company of the acknowledgment that he included in the game. Shortly after his departure, the "Gray Dot" and his message were discovered by

7980-462: The most successful with at least one and four million copies sold, respectively. In 1980, Atari attempted to block the sale of the Activision cartridges, accusing the four of intellectual property infringement. The two companies settled out of court, with Activision agreeing to pay Atari a licensing fee for their games. This made Activision the first third-party video game developer and established

8085-448: The new Atari Corporation under Tramiel released a revised, low-cost 2600 model, and the backward-compatible Atari 7800 , but it was Nintendo that led the recovery of the industry with its 1985 launch of the Nintendo Entertainment System . Production of the Atari 2600 ended in 1992, with an estimated 30 million units sold across its lifetime. Atari, Inc. was founded by Nolan Bushnell and Ted Dabney in 1972. Its first major product

8190-430: The next week. By December 1975, Atari hired Joe Decuir , a recent graduate from University of California, Berkeley who had been doing his own testing on the 6502. Decuir began debugging the first prototype designed by Mayer and Milner, which gained the codename "Stella" after the brand of Decuir's bicycle. This prototype included a breadboard -level design of the graphics interface to build upon. A second prototype

8295-477: The only other major producer of home consoles at the time. Atari engineers recognized, however, the limitation of custom logic integrated onto the circuit board, permanently confining the whole console to only one game. The increasing competition increased the risk, as Atari had found with past arcade games and again with dedicated home consoles. Both platforms are built from integrating discrete electro-mechanical components into circuits, rather than programmed as on

8400-431: The oversaturated home game market, Atari's weakened position led investors to start pulling funds out of video games, beginning a cascade of disastrous effects known as the video game crash of 1983 . Many of the third-party developers formed prior to 1983 were closed, and Mattel and Coleco left the video game market by 1985. In September 1983, Atari sent 14 truckloads of unsold Atari 2600 cartridges and other equipment to

8505-471: The project, Bushnell sold Atari to Warner Communications in 1976. The Atari VCS launched in 1977 with nine games on 2 KB cartridges. Atari ported many of their arcade games to the system, and the VCS versions of Breakout and Night Driver are in color while the arcade originals have monochrome graphics. The system's first killer application was the home conversion of Taito 's arcade game Space Invaders in 1980. Adventure , also released in 1980,

8610-402: The release of the home version of Pong , Cyan's engineers, led by Mayer and Ron Milner, had envisioned a home console powered by new programmable microprocessors capable of playing Atari's current arcade offerings. The programmable microprocessors would make a console's design significantly simpler and more powerful than any dedicated single-game unit. However, the cost $ 100–300 of such chips

8715-477: The same colors as the players; and a 1-pixel ball , which shares the background color. The 1-bit sprites all can be controlled to stretch to 1, 2, 4, or 8 pixels. The system was designed without a frame buffer to avoid the cost of the associated RAM . The background and sprites apply to a single scan line , and as the display is output to the television, the program can change colors, sprite positions, and background settings. The careful timing required to sync

8820-451: The scale it needed, and began considering a sale to a larger firm by early 1976. Atari was introduced to Warner Communications , which saw the potential for the growing video game industry to help offset declining profits from its film and music divisions. Negotiations took place during 1976, during which Atari cleared itself of liabilities, including settling a patent infringement lawsuit with Magnavox over Ralph H. Baer 's patents that were

8925-495: The show at certain points. In the anthology series Black Mirror , the producers have included Easter eggs that reference past episodes, or tie into future episodes, as a means of loosely tying together all episodes into a single Black Mirror universe. The Netflix series Stranger Things had a real-world Easter Egg where a pizza delivery van featured in the show's fourth season had the phone number (805) 45-PIZZA shown on its side. If that number, which translated to 805-457-4992

9030-457: The speed of the audible stepper motor drive to produce specific pitches. The Commodore Amiga 1000 computer includes the signatures of the design and development team embossed on the inside of the case, including Jay Miner and the paw print of his dog, Mitchy. The Commodore Amiga models 500, 600, and 1200 each feature Easter eggs in the form of song titles by the B-52's as white printing on

9135-420: The system was designed for, such as Activision's Pitfall! . By 1982, the Atari 2600 was the dominant game system in North America. Poor decisions by Atari management damaged both the system and company's reputation, most notably the release of two highly anticipated games for the 2600: a port of the arcade game Pac-Man and E.T. the Extra-Terrestrial . Pac-Man became the 2600's highest-selling game, but

9240-534: The television's antenna. Atari developed the Television Interface Adaptor (TIA) chip in the VCS to handle the graphics and conversion to a television signal. It provides a single-color, 20-bit background register that covers the left half of the screen (each bit represents 4 adjacent pixels) and is either repeated or reflected on the right side. There are 5 single-color sprites : two 8-pixel wide players ; two 1 bit missiles , which share

9345-444: Was Pong , released in 1972, the first successful coin-operated video game . While Atari continued to develop new arcade games in following years, Pong gave rise to a number of competitors to the growing arcade game market. The competition along with other missteps by Atari led to financial problems in 1974, though recovering by the end of the year. By 1975, Atari had released a Pong home console , competing against Magnavox ,

9450-415: Was a redesign based on human factor analysis by Henry Dreyfuss Associates . Easter egg (media) The earliest known video game Easter egg is in the 1973 video game Moonlander , in which the player tries to land a Lunar module on the Moon; if the player opts to fly the module horizontally through several of the game's screens, they encounter a McDonald's restaurant, and if they land next to it,

9555-532: Was cheaper than the 6502 because its package included fewer memory-address pins—13 instead of 16. The designers of the Atari 2600 selected an inexpensive cartridge interface that has one fewer address pins than the 13 allowed by the 6507, further reducing the already limited addressable memory from 8 KB (2 = 8,192) to 4 KB (2 = 4,096). This was believed to be sufficient as Combat was only 2 KB. Later games circumvented this limitation with bank switching . The console has 128 bytes of RAM for scratch space,

9660-405: Was completed by March 1976 with the help of Jay Miner , who created a chip called the Television Interface Adaptor (TIA) to send graphics and audio to a television. The second prototype included a TIA, a 6507, and a ROM cartridge slot and adapter. As the TIA's design was refined, Al Alcorn brought in Atari's game developers to provide input on features. There are significant limitations in

9765-570: Was complicated by the use of cartridges. The Atari VCS was launched in September 1977 at $ 199 (equivalent to about $ 1,000 in 2023), with two joysticks and a Combat cartridge; eight additional games were sold separately. Most of the launch games were based on arcade games developed by Atari or its subsidiary Kee Games : for example, Combat was based on Kee's Tank (1974) and Atari's Jet Fighter (1975). Atari sold between 350,000 and 400,000 Atari VCS units during 1977, attributed to

9870-404: Was designed to be compatible with the cathode-ray tube television sets produced in the late 1970s and early 1980s, which commonly lack auxiliary video inputs to receive audio and video from another device. Therefore, to connect to a TV, the console generates a radio frequency signal compatible with the regional television standards ( NTSC , PAL , or SECAM ), using a special switch box to act as

9975-412: Was dialed, it led to a special message from Argyle, the fictional restaurant's delivery driver. Security author Michel E. Kabay discussed security concerns of Easter eggs in 2000, saying that, while software quality assurance requires that all code be tested, it is not known whether Easter eggs are. He said that, as they tend to be held as programming secrets from the rest of the product testing process,

10080-516: Was far outside the range that their market would tolerate. Atari had opened negotiations to use Motorola's new 6800 in future systems. In September 1975, MOS Technology debuted the 6502 microprocessor for $ 25 at the Wescon trade show in San Francisco. Mayer and Milner attended, and met with the leader of the team that created the chip, Chuck Peddle . They proposed using the 6502 in

10185-547: Was including its 1982 version of Pac-Man along with Combat (1977). The Gemini initially came bundled with Coleco's 1982 port of Donkey Kong , but at some point also included Carnival , Mouse Trap and Front Line . Sears also offered a version of the Gemini with both Donkey Kong and Mouse Trap included as separate cartridges. Atari 2600 The Atari 2600 is a home video game console developed and produced by Atari, Inc. Released in September 1977 as

10290-484: Was one of the first action-adventure video games and contains the first widely recognized Easter egg . The popularity of the VCS led to the founding of Activision and other third-party game developers and competition from the Intellivision and, later, ColecoVision consoles. Games grew to use four or more times the storage size of the launch games with significantly more advanced visuals and gameplay than

10395-432: Was panned for being inferior to the arcade version. E.T. was rushed to market for the holiday shopping season and was similarly disparaged. Both games, and a glut of third-party shovelware , were factors in ending Atari's relevance in the console market, contributing to the video game crash of 1983 . Warner sold the assets of Atari's consumer electronics division to former Commodore CEO Jack Tramiel in 1984; in 1986

10500-562: Was redesigned for the 7800 by Barney Huang. The cost-reduced 1986 model, sometimes referred to as the "2600 Jr.", has a smaller form factor with an Atari 7800 -like appearance. It was advertised as a budget gaming system (under $ 50 ) with the ability to run a large collection of games. Released after the video game crash of 1983, and after the North American launch of the Nintendo Entertainment System ,

10605-539: Was released later for a series of games aimed at a younger audience. The CX22 Trak-Ball controller was announced in January 1983 and is compatible with the Atari 8-bit computers. There were two attempts to turn the Atari 2600 into a keyboard-equipped home computer : Atari's never-released CX3000 "Graduate" keyboard, and the CompuMate keyboard by Spectravideo which was released in 1983. The initial production of

10710-573: Was replaced with the CX40 model designed by James C. Asher. Because the Atari joystick port and CX40 joystick became industry standards, 2600 joysticks and some other peripherals work with later systems, including the MSX , Commodore 64 , Amiga , Atari 8-bit computers , and Atari ST . The CX40 joystick can be used with the Master System and Sega Genesis , but does not provide all the buttons of

10815-587: Was showcased on June 4, 1977, at the Summer Consumer Electronics Show with plans for retail release in October. The announcement was purportedly delayed to wait out the terms of the Magnavox patent lawsuit settlement, which would have given Magnavox all technical information on any of Atari's products announced between June 1, 1976, and June 1, 1977. However, Atari encountered production problems during its first batch, and its testing

10920-443: Was sufficiently different to avoid patent conflicts, but the exterior components were directly influenced by the Channel F to help work around the static electricity concerns. Atari was still recovering from its 1974 financial woes and needed additional capital to fully enter the home console market, though Bushnell was wary of being beholden to outside financial sources.> Atari obtained smaller investments through 1975, but not at

11025-537: Was the Video Arcade II, released during the fall of 1982. Sears released versions of Atari's games with Tele-Games branding, usually with different titles. Three games were produced by Atari for Sears as exclusive releases: Steeplechase , Stellar Track , and Submarine Commander . The Atari 2800 is the Japanese version of the 2600 released in October 1983. It is the first Japan-specific release of
