{{Simulation fallout 4 is a genre of flight simulator video games that lets players experience space flight to varying degrees of realism . Common mechanics include space exploration , space trade and space combat .
101-461: Galaxy Game is a space combat arcade game developed in 1971 during the early era of video games . Galaxy Game is an expanded version of the 1962 Spacewar! , potentially the first video game to spread to multiple computer installations. It features two spaceships, "the needle" and "the wedge", engaged in a dogfight while maneuvering in the gravity well of a star. Both ships are controlled by human players. Created by Bill Pitts and Hugh Tuck,
202-404: A media franchise consisting of space combat simulation video games, an animated television series , a feature film , a collectible card game , a series of novels , and action figures . Game designer Chris Crawford said in an interview that Wing Commander "raised the bar for the whole industry", as the game was five times more expensive to create than most of its contemporaries. Because
303-524: A timesharing system "out of the box". Timesharing had been available for other machines, most famously the PDP-1 at Project MAC, but the PDP-6 was the first such system to be supported by the manufacturer. Worldwide, only 23 PDP-6's were sold, the smallest number of any DEC machine. It was complex and expensive to build, as well as difficult to install and get operational at the customer's site. Additionally,
404-449: A 256 kword main memory , about 1 MB in modern terms. Memory was implemented using magnetic cores ; a typical system included 32,768 words (equivalent to 144 kB on modern machines). The use of a 36-bit word allowed two 18-bit addresses to be stored in a single memory location; this made it suited to the storage of a cons , a widely used structure in the Lisp language, meaning
505-455: A blue fiberglass casing, and the PDP-11 was housed inside one of the consoles. By the time of its installation, the pair had spent US$ 65,000 (equivalent to about $ 473,000 in 2023) on the project, but were unable to make the game commercially viable. The second prototype remained in the student union building until 1979, when the display processor became faulty. It was restored and placed in
606-543: A building he found out to be the location of the Stanford Artificial Intelligence Project , which held a DEC PDP-6 time-sharing computer system with 20 Teletype consoles connected to it. Fascinated by the computer and having taken several introductory computer classes, Pitts convinced the head of the project, Lester Earnest , to let him use the computer after hours. Soon, Pitts had ceased going to classes, instead spending his nights in
707-404: A coin-operated version of Spacewar , the pair, with assistance from Tuck's family, bought a PDP-11 and started working on a prototype. They spent a total of US$ 20,000 (equivalent to about $ 150,000 in 2023) to build a single arcade machine for two players, like the original Spacewar , deciding to price the game at ten cents per play or 25 cents for three games, with the winner of a match given
808-584: A company called Mini-Computer Applications in June 1971 to operate the game as it neared completion. The development of the prototype machine took around three and a half months. By August, they were well into development and had gotten permission to place the machine at the Tresidder student union building at Stanford as a test site. It was then that they received a call from Nolan Bushnell , who had heard of their project and wanted to show them his similar project he
909-405: A device was still unfeasible due to the cost of computers, and the pair did not pursue the project. In 1971, however, Pitts, who by then had graduated and was working at Lockheed as a PDP-10 programmer, learned of the 1970 DEC PDP-11 , which was sold for around US$ 14,000. While this was still too high for a commercially viable product, as most electronic games in arcades cost around US$ 1,000 at
1010-543: A discussion with senior vice president Jonathan Rosenberg, who had been hired as a 13 year old by Tuck and Pitts in the mid-1970s to keep the machine cleaned. It has since returned to the museum as a playable exhibit. Space combat simulation Some games in the genre aim to recreate a realistic portrayal of space flight, involving the calculation of orbits within a more complete physics simulation than pseudo space flight simulators. Others focus on gameplay rather than simulating space flight in all its facets. The realism of
1111-523: A faithful coin-operated Spacewar game and paid little attention to the business side of the project; he felt that Computer Space had been more commercially successful because Bushnell had focused more on the business side of his idea than the technical. The second Galaxy Game prototype remained on display in the Tresidder building until May 1979, when it was removed due to the display processor becoming unreliable. Throughout its time on display, it remained popular, with "ten to twenty people gathered around

They used a PDP-11/20 version of the PDP-11 ( US$ 14,000), a Hewlett-Packard 1300A Electrostatic Display ( US$ 3,000), and spent the remainder on the coin acceptors, joysticks, wiring, and casing. Pitts build the computer hardware and handled the programming, while Tuck, a mechanical engineer, designed the enclosing cabinet . The display adapter for the monitor was built by Ted Panofsky,
1313-516: A game a simulator. Many of the pseudo simulators feature faster than light travel . Examples of true simulators which aim at piloting a space craft in a manner that conforms with the laws of nature include Orbiter , Kerbal Space Program and Microsoft Space Simulator . Examples of more fantastical video games that bend the rules of physics in favor of streamlining and entertainment, include Wing Commander , Star Wars: X-Wing and Freelancer . The modern space flight game genre emerged at
1414-440: A mix of different methods. The ship the player controls is generally larger than that in pure space combat simulator. Notable examples of the genre include Elite , the X series , Wing Commander: Privateer , Freelancer , and No Man's Sky . In some instances, plot plays only a limited role and only a loose narrative framework tends to be provided. In certain titles of the X series , for instance, players may ignore
1515-408: A monitor, which prohibited the original Spacewar or any game of the time from reaching beyond a narrow, academic audience. The original developers of Spacewar considered ways to monetize the game, but saw no options given the high price of the computer it ran on. In 1966, Stanford University student Bill Pitts, who had a hobby of exploring the steam tunnels and buildings of the campus, broke into
1616-454: A multinational cast of pilots from the " Terran Confederation " flying missions against the predatory, aggressive Kilrathi , a feline warrior race (heavily inspired by the Kzinti of Larry Niven 's Known Space universe). Wing Commander (1990) was a best seller and caused the development of competing space combat games, such as LucasArts ' X-Wing . Wing Commander eventually became
1717-528: A prototype of their Computer Space game in a bar near Stanford and had found a commercial manufacturer for the game in Nutting Associates. They were curious about what Tuck and Pitts had done to make a commercially competitive version of the game, but were relieved, though also somewhat disappointed, to find that they had not solved that problem yet. Tuck and Pitts, on the other hand, while impressed with Bushnell's hardware were not impressed with
1818-571: A single disk drive, resulted in "real time-sharing (and) could easily handle 20-30 users." Stanford's PDP-6 was shown at DECUS in 1984. The machine was transferred to a DEC warehouse after that event. There are no records of this machine being given to the Computer Museum, which was not part of DEC in 1984. In the late 1990s Compaq donated the contents of the DEC internal archives to The Computer Museum History Center. The Fast Memory cabinet from
1919-458: A source of bright young future employees to assist in the hardware and software development for those future models. The sales were so slow that DEC eventually decided to abandon the system and announced that they would not build any more 36-bit machines. Fortunately, this decision was reversed and a new 36-bit system was designed using the new Flip-Chip modules and much smaller system boards to improve density and reliability. The resulting design
2020-467: A star map with multiple ports buying and selling 6 commodities. It was written in BASIC . Star Raiders was introduced in 1980 for the then-new Atari 8-bit computers and became the killer app for the system. Doug Neubauer created the game as a combination of Star Wars and the text-based Star Trek mainframe game. Using smoothly scaled 2D sprites and 3D particles to mimic a first person view of
2121-407: A volume of space, Star Raiders simulates clearing sectors of enemy ships while managing resources and damage to the ship's different systems. In addition to forward and rear views from the ship, the game provides both a galactic map and sector scanner to show enemy and friendly starbase locations. The game does not pause while these displays are active; they keep updating in real-time. It is one of

FlightGear can accurately handle speeds from subsonic, transonic , through to high hypersonic or re-entry regimes with a flight dynamics engine that can incorporate windtunnel data or computational fluid dynamics , and uses a 3d model of gravity used for spaceflight based on spherical harmonics which can simulate
2424-480: Is a graphics display connected to a computer," and contributor Martin Graetz recalled in 1981 that as the game initially spread it could be found on "just about any research computer that had a programmable CRT". Although the game was widespread for the era, it was still very limited in its direct reach: the PDP-1 was priced at US$ 120,000 (equivalent to about $ 903,000 in 2023) and only 55 were ever sold, most without

The game was completed and released in 2014, and expansions are being released in stages, or "seasons". Born Ready Games also closed a successful Kickstarter campaign at the end of 2012, having raised nearly $ 180,000 to assist with the completion of Strike Suit Zero . The game

FlightGear simulates orbital and atmospheric flight, but as of 2021 does not cover flight between planets (although its flight dynamics engine supports Mars and has been used to model the NASA ARES glider ). The simulation has been continually developed into modern times, as FlightGear

Elite was also named #12 on IGN 's 2000 "Top 25 PC Games of All Time" list, the #3 most influential video game ever by the Times Online in 2007, and "best game ever" for the BBC Micro by Beebug Magazine in 1984. Elite ' s sequel, Frontier: Elite II , was named #77 on PC Zone 's "101 Best PC Games Ever" list in 2007. Similar praise has been bestowed elsewhere in

The ships have a limited number of torpedoes and a limited supply of fuel, which is used when the player fires his thrusters. Torpedoes are fired one at a time, and there is a cooldown period between launches. The ships follow Newtonian physics , remaining in motion even when

3232-408: The PDP-11 in the attic by a 100-foot cable. In December, it was moved to a coffee shop on the first floor. It was very successful; Pitts later said that the machine attracted crowds of people "ten-deep" watching the players. They briefly attached a second monitor hanging above the console so that the watchers could more easily see the game. The low prices meant that they did not come close to making back
3333-431: The PDP-6 could store a cons in a single word and read and write one in a single operation. The instruction set architecture could be categorized as "one-and-a-half address". The opcode was stored in the most significant bits of the 36-bit word, using 9 bits. The next four bits indicate which of sixteen registers to apply the instruction to. The last 18 bits indicated an address. Thus, a typical instruction might be "add
3434-508: The PDP-6 was its re-implementation using modern silicon transistors and the newer Flip-Chip module packaging to produce the PDP-10 . The instruction sets of the two machines are almost identical. The PDP-10 was less expensive and more reliable, and about 1500 were sold during its lifetime. DEC's first products were not computers but a series of plug-in circuits known as Digital Laboratory Modules that performed digital logic. Users could wire
3535-710: The Stanford computer science department in 1997, then moved to the Computer History Museum in 2000, where it remains as of 2017. At the beginning of the 1970s, video games existed almost entirely as novelties passed around by programmers and technicians with access to computers, primarily at research institutions and large companies. One of these games was Spacewar! , created in 1962 for the Digital Equipment Corporation (DEC) PDP-1 minicomputer by Steve Russell and others in
3636-476: The behaviour of the spacecraft, but not orbital mechanics. Space combat games tend to be mission-based, as opposed to the more open-ended nature of space trading and combat games. The general formula for the space trading and combat game , which has changed little since its genesis, is for the player to begin in a relatively small, outdated ship with little money or status and for the player to gain in status and power through trading, exploration, combat or
3737-447: The coin acceptors were sourced from jukebox manufacturer Rowe International, and the joysticks found at a military surplus store as remainders from B-52 bomber controls. The code for the game was based on a version of Spacewar running on a PDP-10 in the Stanford artificial intelligence lab, but modified with additional features. Pitts and Tuck renamed their product from Spacewar to Galaxy Game due to anti-war sentiment and founded
3838-399: The computer hardware with custom-built parts. They had soon discovered that while a general-purpose computer cheap enough for an arcade game would not be powerful enough to run enough games of Spacewar to be profitable, a computer purpose-built for solely running one game could be made for as low as US$ 100. By August 1971 when Bushnell called Tuck and Pitts, he and Dabney had already displayed
3939-418: The computer lab interacting with the graduate and postgraduate students and playing Spacewar on the PDP-6. Pitts often played against Hugh Tuck, a student at California Polytechnic State University who was a friend from high school. During one Spacewar session that took place, depending on the source, between 1966 and 1969, Tuck remarked that a coin-operated version of the game would be very successful. Such

Due to issues with space and maintenance, in 2000 it was moved into the Computer History Museum in Mountain View, California , in the displayed storage section. In August 2010, the museum loaned the console to Google to be placed at their headquarters campus at the request of Pitts—who wanted the game to be played as well as displayed—due to
4141-488: The consoles rather than in a separate location. While the original plan had been to work on driving down the development costs after the initial prototype, the popularity of the game convinced the pair to instead focus on making a better machine that could run multiple games to recoup the upfront investment. The new version was installed in a cafe in the student union building in June 1972, though with only two monitors due to space restrictions. The original Galaxy Game prototype

4242-415: The core gameplay elements of directly controlling the flight of some sort of space vessel, generally armed, and of navigating from one area to another for a variety of reasons. As technology has improved it has been possible to implement a number of extensions to gameplay, such as dynamic economies and cooperative online play . Overall, however, the core gameplay mechanics of the genre have changed little over
4343-407: The cost. The PDP-5 was built from the same components, but used a 12-bit word for even greater savings and sold for about US$ 27,000 (equivalent to $ 268,709 in 2023). The PDP-6 was DEC's first "big" machine. It used 36-bit words , in common with other large computers at the time from companies like IBM , Honeywell and General Electric . Unlike those machines, the PDP-6 was supplied with
4444-728: The definition is expanded to include decision making and planning, then Buzz Aldrin's Race Into Space (1992) is also notable for historical accuracy and detail. In this game, the player takes the role of Administrator of NASA or Head of the Soviet Space Program with the ultimate goal of being the first side to conduct a successful human Moon landing . Orbiter and, to an extent, Space Shuttle Mission 2007 , provide more elaborate simulations. They have 3D virtual cockpits and external views. Orbiter has been continually developed into modern times including having modern graphics, while others above have not been. FlightGear
4545-514: The desired configuration, or in setting autopilots . Real time hands on piloting can happen, depending on the simulated spacecraft. For example, it is common to use a joystick analog control to land a Space Shuttle (or any other spaceplane ) or the Apollo Lunar Module (or similar landers). Dockings can be performed more precisely using the numerical keypad . Overall, the simulations have more complex control systems than game, with
4646-703: The development of Elite (the main character in Traveller is named "Jamison"; the main character in Elite is named "Jameson") and Jumpgate Evolution . The Wing Commander (1990–2007) series from Origin Systems, Inc. was a marked departure from the standard formula up to that point, bringing space combat to a level approaching the Star Wars films. Set beginning in the year 2654, and characterized by designer Chris Roberts as " World War II in space", it features
4747-458: The era. Large machines generally used a 36-bit word length , but there were many variations. The PDP-1's 18-bit length allowed the machine to be simpler and less expensive than these, at US$ 120,000 (equivalent to $ 1,254,247 in 2023). Proposals for a PDP-2 and PDP-3 were turned down, and DEC's next machine, the PDP-4 , was essentially a smaller and less-expensive PDP-1 that sold for roughly half
4848-452: The first truly open-ended game. It is to this day one of the most ambitious games ever made, residing in only 22 kilobytes of memory and on a single floppy disk. The latest incarnation of the franchise, titled Elite: Dangerous , was released on 16 December 2014, following a successful Kickstarter campaign. Though not as well known as Elite , Trade Wars is noteworthy as the first multiplayer space trader. A BBS door , Trade Wars
4949-409: The first video game to be available outside a single research institute. Spacewar was extremely popular in the small programming community in the 1960s and was widely recreated on other minicomputer and mainframe computers of the time, later migrating to early microcomputer systems. Early computer scientist Alan Kay noted in 1972 that "the game of Spacewar blossoms spontaneously wherever there
5050-471: The game itself. They felt that Computer Space , a single-player game without the central gravity well of the original game, was a pale imitation of Spacewar , while their own Galaxy Game was a superior adaptation of the game. In November 1971, the Galaxy Game prototype debuted. The veneered walnut console, complete with seats for players, was located on the second floor of the building and connected to
5151-492: The game that impacted him most on the Commodore 64. Developers of Jumpgate Evolution , Battlecruiser 3000AD , Infinity: The Quest for Earth , Hard Truck: Apocalyptic Wars and Flatspace likewise all claim Elite as a source of inspiration. Elite was named one of the sixteen most influential games in history at Telespiele, a German technology and games trade show, and is being exhibited at such places as

#17327984247195252-417: The game was highly successful, other publishers had to match its production value in order to compete. This forced a large portion of the video game industry to become more conservative, as big-budget games need to be an assured hit for it to be profitable in any way. Crawford opined that Wing Commander in particular affected the marketing and economics of computer games and reestablished the "action game" as
5353-616: The games that inspired Elite and the Wing Commander series. It also resulted in direct clones, including Space Spartans for Intellivision and Starmaster for the Atari 2600, both from 1982. Elite has made a lasting impression on developers, worldwide, extending even into different genres. In interviews, senior producers of CCP Games cited Elite as one of the inspirations for their acclaimed MMORPG EVE Online . Þórólfur Beck , CCP's co-founder, credits Elite as
5454-561: The genre is very popular, but some people have complained that, in some titles, the leeway given to the player too often is only superficial, and that, in reality, the roles offered to players are very similar, and open-ended play too frequently restricted by scripted sequences. As an example, Freelancer has been in one reviewer's opinion critiqued as being rigid in its narrative structure, being in one case compared negatively with Grand Theft Auto , another series praised for its open-ended play. All space trading and combat games feature
5555-445: The hypothetical Alcubierre drive , but this is implemented in a realistic method to complement the more realistic elements of the game. Most games in the space combat genre feature futuristic scenarios involving space flight and extraplanetary combat. Such games generally place the player into the controls of a small starfighter or smaller starship in a military force of similar and larger spaceships and do not take into account
5656-399: The initial prototype cost US$ 20,000 (equivalent to about $ 150,000 in 2023) to build. It consisted of a Digital Equipment Corporation PDP-11 minicomputer attached by a cable to a wooden console with a monitor, controls, and seats. It charged players 10 cents per game or 25 cents for three, and drew crowds "ten-deep". This was one of the first coin-operated video games; the prototype
5757-416: The keyboard and mouse combination (or gamepad if such is the case). The lack of uptake among the majority of modern gamers has also made joysticks a sort of anachronism, though some new controller designs and simplification of controls offer the promise that space sims may be playable in their full capacity on gaming consoles at some time in the future. In fact, X3: Reunion , sometimes considered one of
5858-400: The latter games is limited to what the game designer deems to be appropriate for the gameplay, instead of focusing on the realism of moving the spacecraft in space. Some "flight models" use a physics system based on Newtonian physics , but these are usually limited to maneuvering the craft in its direct environment, and do not take into consideration the orbital calculations that would make such
5959-406: The limit being the physical reproduction of the actual simulated spacecraft (see Simulation cockpit ). Early attempts at 3D space simulation date back as far as 1974's Spasim , an online multi-player space simulator in which players attempt to destroy each other's ships. The earliest known space trader dates to 1974's Star Trader , a game where the entire interface was text-only and included
6060-534: The lunar surface in a craft resembling the Apollo Lunar Module , while Perilune (2019) is an example of a lunar landing simulation with realistic physics designed for Android mobile devices. The game/program SpaceEngine includes a realistic space flight simulator within its full scale representation of the universe (including both real and procedurally generated astronomical objects), utilizing realistic orbital mechanics and an atmospheric model for certain flyable shuttles. It also includes interstellar travel using
6161-451: The machine was an early version of what later became TOPS-10 , and several sites made custom versions of the system, which was available in source code form. MIT's Incompatible Timesharing System (ITS) operating system also began on the PDP-6. Although it was possible to time-share a PDP-6 without a disk drive, configuring it with four dual DECtape drives "could effectively support about 4-6 simultaneous users." The same system, with

Pitts later claimed that by the time the machine was removed, it had managed to make back the original investment. After its removal, the machine was dismantled, with the computer parts stored in an office and the casing outdoors. The unit was restored in 1997 with a recreated display processor and put on display for several years in
6363-544: The mechanical coupling made it highly likely that fixing one fault would cause another. There was also a great fear of powering off a PDP-6, since it would generally result in at least one 6205 board failing. The experience with the 6205 led the designers of the first models of PDP-10, the KA10 and KI10, to use only small boards. It was not until the KL10 that large boards were used again. The PDP-6 supported time-sharing through
6464-407: The media from time to time. Elite is one of the most popularly requested games to be remade, and some argue that it is still the best example of the genre to date, with more recent titles—including its sequels—not rising up to its level. It has been credited as opening the door for future online persistent worlds , such as Second Life and World of Warcraft , and as being
6565-538: The modules together to perform specific tasks. DEC soon introduced the PDP-1 which was built out of large numbers of these modules, now known as System Building Blocks or System Modules . The PDP-1 used an 18-bit word. Word lengths in the early 1960s were generally some multiple of six bits, as the character codes of the era were 6 bits long and it was also a useful size for storing binary-coded decimal digits with an optional sign, as commonly used on IBM machines of
6666-455: The more cumbersome and difficult series to master within the trading and combat genre, was initially planned for the Xbox but later cancelled. Realistic simulators feature spacecraft systems and instrument simulation, using a combination of extensive keyboard shortcuts and mouse clicks on virtual instrument panels . Most of the maneuvers and operations consist of setting certain systems into
6767-483: The most lucrative type of computer game. The seeming decline of the space flight simulators and games in the late 1990s also coincided with the rise of the RTS , FPS and RPG game genres, with such examples as Warcraft , Doom and Diablo . The very things that made these games classics, such as their open-endedness, complex control systems and attention to detail, have been cited as reasons for their decline. It

However, open-source and enthusiast communities managed to produce some working, modern titles (e.g. Orbiter Spaceflight Simulator ); and 2011's commercially released Kerbal Space Program was notably well-received, even by the aerospace community. Some more recent games, most notably Elite: Dangerous , have brought new attention to
6969-406: The original, optional modifications to the game to have faster ships, faster torpedoes, to remove the star and its gravitational field or reverse the gravity to push away from the star, and to remove the wraparound effect. The movement of the ships was controlled with a joystick , while the torpedoes, hyperspace, and game options are controlled via a panel of buttons. After deciding to begin work on
7070-539: The other side in a wraparound effect. A hyperspace feature, or "panic button", can be used as a last-ditch means to evade enemy torpedoes by moving the player's ship to another location on the screen after disappearing for a few seconds, but the reentry from hyperspace occurs at a random location, and there is an increasing probability of the ship exploding with each use. Player controls include clockwise and counterclockwise rotation, forward thrust, firing torpedoes, and hyperspace. Galaxy Game features, as improvements over
7171-491: The personal computer allow a player to utilise a combination of the WASD keys of the keyboard and mouse as a means of controlling the game (games such as Microsoft's Freelancer use this control system exclusively ). By far the most popular control system among genre enthusiasts, however, is the joystick . Most fans prefer to use this input method whenever possible, but expense and practicality mean that many are forced to use
7272-507: The physics of space flight, often citing some technological advancement to explain the lack thereof. The prominent Wing Commander , X-Wing and Freespace series all use this approach. Exceptions include Independence War , Independence War 2 and the Star Trek: Bridge Commander series, which model craft at a larger scale and/or in a more strategic fashion. I-War also features Newtonian style physics for
7373-418: The player is not accelerating, though the ships can rotate at a constant rate without inertia. Each player controls one of the ships and must attempt to shoot down the other ship while avoiding a collision with the star. Flying near the star can provide a gravity assist to the player at the risk of misjudging the trajectory and falling into the star. If a ship moves past one edge of the screen, it reappears on

Following Elite were games such as The Halley Project (1985), Echelon (1987) and Microsoft Space Simulator (1994). Star Luster , released for
7575-419: The plot for as long as they wish and are even given the option to disable the plot completely and instead play in sandbox mode . Many games of this genre place a strong emphasis on factional conflict, leading to many small mission-driven subplots that unravel the tensions of the galaxy. Games of this type often allow the player to choose among multiple roles to play and multiple paths to victory. This aspect of
7676-510: The point when home computers became sufficiently powerful to draw basic wireframe graphics in real-time. The game Elite is widely considered to be the breakthrough game of the genre, and as having successfully melded the "space trading" and flight sim genres. Elite was highly influential upon later games of its type, although it did have some precursors. Games similar to Elite are sometimes called " Elite -clones". Space flight games and simulators, at one time popular, had for much of
7777-422: The price of the PDP-11, but they were excited by the game's reception and had not intended the prototype to be profitable. As the initial Galaxy Game prototype was displayed to the public a few months after the first Computer Space prototype, it is believed to be the second video game to charge money to play. As a result of the reception to Galaxy Game , Pitts and Tuck started work on an expanded prototype. For
7878-545: The programming community at the Massachusetts Institute of Technology . The two-player game has the players engage in a dogfight between two spaceships, set against the backdrop of a starfield, with a central star exerting gravitational force upon the ships. The game was copied to several of the early minicomputer installations in American academic institutions after its initial release, making it potentially
7979-477: The sales force found the PDP-6 to be a "hard sell". Nevertheless, the company later considered the PDP-6 to be a success: Because the PDP-6 was the first computer to offer elegant, powerful capabilities at a low price, a great many of the PDP-6s built found their way into university and scientific environments, giving DEC a strong foothold in that market and providing both educated customer input for future models and
8080-410: The second machine, they built a full blue fiberglass casing for the consoles, improved the quality of the joysticks with the help of a machine shop, and modified the computer with a newer display processor to support up to four games at once on different monitors—either multiple simultaneous separate games or up to four players playing the same game on two screens. They also placed the PDP-11 inside one of
8181-441: The space combat or trading subgenres. Mods for the game such as Real Solar System, Realism Overhaul and Kerbalism can be installed to add more realism to the game by replacing the standard in-game solar system with a 1:1 replica of the real Solar System as well as adding more realistic rocket engines, radiation, life support and other elements to make the game more realistic. The game Lunar Flight (2012) simulates flying around
8282-672: The space trading and combat game subgenre. Realistic space simulators seek to represent a vessel's behaviour under the influence of the laws of physics . As such, the player normally concentrates on following checklists or planning tasks. Piloting is generally limited to dockings, landings or orbital maneuvers. The reward for the player is on mastering real or realistic spacecraft, celestial mechanics and astronautics . Classical games with this approach include Space Shuttle: A Journey into Space (1982), Rendezvous: A Space Shuttle Simulation (1982), The Halley Project (1985), Shuttle (1992) and Microsoft Space Simulator (1994). If
8383-451: The summer of 1964. It was an expansion of DEC's existing 18-bit systems to use a 36-bit data word, which was at that time a common word size for large machines like IBM mainframes . The system was constructed using the same germanium individual transistor -based System Module layout as DEC's earlier machines, like the PDP-1 and PDP-4 . The system was designed with real-time computing use in mind, not just batch processing as
8484-535: The surface within the cities. Many other space sim games have allowed the player to exit their ship on planets, but the "walking" is just clicking on a location such as "Bar," "Ship Dealer," etc. The game also featured a unique story line involving cryogenics . SunDog: Frozen Legacy was also released on the Atari ST in 1985. Some tabletop and board games, such as Traveller or Merchant of Venus , also feature themes of space combat and trade. Traveller influenced
8585-422: The time, Tuck and Pitts felt it was low enough to build a prototype to determine interest and optimal per-game pricing. The gameplay of Galaxy Game , like Spacewar! , involves two monochrome spaceships called "the needle" and "the wedge" (though their appearances have been modified for the coin-op version) each controlled by a player, attempting to shoot each other while maneuvering on a two-dimensional plane in
8686-555: The twisting force caused by gravity varying over a craft. It has an accurate celestial simulation that also feeds star tracker instruments for navigation. FlightGear has the ability to accelerate time supported by the fact that the physics simulation runs on a separate clock than the visuals - this is very important to simulate long space missions. Being modern, FlightGear has realistic graphics and an orbital renderer that can handle calculations of light scattering and auroral emission with huge distances involved. Of particular note
8787-479: The use of a status bit selecting between two operating modes ("Executive" and "User", with access to input/output (I/O), etc., being restricted in the latter), and a single relocation/protection register which allowed a user's address space to be limited to a set section of main memory (a second relocation/protection register for shareable "high segments" was added on the PDP-10). The main operating system used on
8888-431: The value in 1234 is 2345, the resulting instruction would add the value in 2345 to register 4. This sort of access pattern was common as it allowed tables to be scanned over using a single instruction and then changing the value in memory to point to another location. The remaining four bits offered a similar functionality by selecting a second register as an index register , allowing memory to be stepped through by changing
8989-447: The value in memory location 1234 to the value in register 4". Thus the format contains one-and-a-half addresses, the half being the register. This left another five bits in the instruction word, bits 13 through 17. Bit 13 indicated the address was indirect; instead of the value stored in address 1234 being added to the selected register, the value in 1234 was interpreted as another address, the value in that location used. For instance, if
9090-510: The value in the register rather than in main memory , which is generally faster. The registers in the PDP-6 were simply the first 16 memory locations of main memory. Most, if not all, PDP-6 systems were equipped with the optional Type 162 "Fast Memory", which constructed these 16 memory locations from discrete-transistor flip-flops. These operated four times as fast as the core memory . The PDP-6 weighed about 1,300 pounds (590 kg), 1,700 pounds (770 kg) with "Fast Memory". The PDP-6
9191-480: The years. Besides the array of space-themed trade and combat games, there also exist a small number of games with similar mechanics, but with a less traditional historical setting. These include the Sid Meier's Pirates! and Mount and Blade franchises. Some more recent games, such as 2003's EVE Online , have expanded the scope of the experience by including thousands of simultaneous online players in what
9292-439: Was believed that no major new space sim series would be produced as long as the genre relied on complex control systems such as the keyboard and joystick. There were outliers, however, such as the X series (1999–2018) and Eve Online . Crowdfunding has been a good source for space sims in recent years, however. In November 2012 Star Citizen set a new record, managing to raise more than $ 114 million as of May 2016, and
9393-520: Was completed and released in January 2013. Lastly, the non-linear roguelike-like space shooter Everspace garnered almost $ 250,000 on Kickstarter, was released in May 2017. The open source community has also been active, with projects such as FS2 Open and Vega Strike serving as platforms for non-professional efforts. Unofficial remakes of Elite and Privateer are being developed using
9494-435: Was displayed at several locations around the area, but was not as successful as it had been at the student union building. By the time the second prototype was completed the pair had spent US$ 65,000 on the project and had no feasible way of making up the cost with the machine or commercial prospects for a wider release. Pitts later explained that he and Tuck had been focused on the engineering and technical challenges of producing
9595-421: Was infamous because of the 6205 board, a large (11 × 9 inches) board which contained 1 bit of arithmetic register (AR), memory buffer (MB), and multiplier-quotient register (MQ). The CPU was built from 36 such cards. It had 88 transistors, a two-sided PC etch, two 18-pin and two 22-pin connectors (two on each side of the module). Because of all these connectors, swapping this module was a major undertaking, and
9696-515: Was installed in November 1971 at the Tresidder student union building at Stanford University , only a few months after a similar display of a prototype of Computer Space , making it the second known video game to charge money to play. The pair built a second prototype, replacing the first in Tresidder in June 1972. It featured the capability to play multiple games simultaneously on four monitors, though due to space restrictions only two consoles with monitors were actually installed. These consoles had
9797-596: Was named the #10 best PC game by PC World Magazine . Other notable early examples include Space Shuttle: A Journey into Space (1982), Rendezvous: A Space Shuttle Simulation (1982), and Star Trek: Strategic Operations Simulator (1982), which featured five different controls to learn, six different enemies, and 40 different simulation levels of play, making it one of the most elaborate vector games ever released. Other early examples include Nasir Gebelli 's 1982 Apple II computer games Horizon V which featured an early radar mechanic and Zenith which allowed
9898-441: Was released in 1966 as the PDP-10 . DEC describes this machine as the successor to the PDP-6. Although it was program-compatible with the PDP-6, it ran roughly twice as fast, had both timesharing and batch processing features, and offered a wide variety of expansions and input/output options. It was far more successful and eventually sold about 1,500 machines. Addressing remained 18-bit , as in earlier DEC machines, allowing for
9999-470: Was released in 1984 as an entirely different branch of the space trader tree, having been inspired by Hunt the Wumpus , the board game Risk , and the original space trader, Star Trader . As a pure space trader, Trade Wars lacked any space flight simulator elements, instead featuring abstract open world trading and combat set in an outer space populated by both human and NPC opponents. In 2009, it
10100-453: Was typical for most mainframes. Using a 36-bit word with 18-bit addresses allowed it to efficiently store the cons structure found in the Lisp language, which made it particularly useful in artificial intelligence labs like Project MAC at MIT . It was also complex, expensive, and unreliable as a result of its use of so many early-model transistors. Only 23 were sold, at prices ranging from $ 120,000 to $ 300,000. The lasting influence of
10201-424: Was working on. Bushnell had also played Spacewar during the 1960s and wanted to make an arcade game version of it, but had gone in a different technological direction. He and Ted Dabney had initially started with a US$ 4,000 Data General Nova computer which they thought would be powerful enough to run multiple simultaneous games of Spacewar ; when it turned out to not be, they had started investigating replacing
