The game was initially controlled with switches on the PDP-1, though Bob Saunders built an early gamepad to reduce the difficulty and awkwardness of controlling the game.
It was extremely popular in the small programming community in the s and the public domain code was widely ported and recreated at other computer systems at the time, especially after computer systems with monitors became more widespread towards the end of the decade.
It has also been recreated in more modern programming languages for PDP-1 emulators. It directly inspired many other electronic games, such as the first commercial arcade video games , Galaxy Game and Computer Space , and later games such as Asteroids In , Spacewar!
During the s, various computer games were created in the context of academic computer and programming research and for demonstrations of computing power, especially after the introduction later in the decade of smaller and faster computers on which programs could be created and run in real time as opposed to being executed on a schedule.
A few programs, however, were intended both to showcase the power of the computer they ran on and as entertainment products; these were generally created by undergraduate and graduate students and university employees, such as at the Massachusetts Institute of Technology MIT , where staff and students were allowed on occasion to develop programs for the TX-0 experimental computer.
The games included Tic-Tac-Toe , which used a light pen to play a simple game of noughts and crosses against the computer, and Mouse in the Maze , which used a light pen to set up a maze of walls for a virtual mouse to traverse.
The PDP-1 was to complement the older TX-0, and like it had a punched tape reader and writer, and additionally accepted input from a panel of switches and could output to a cathode-ray tube display.
Over the summer before its arrival a group of students and university employees had been pondering ideas for programs that would demonstrate the new computer's capabilities in a compelling way.
They referred to their collaboration as the "Hingham Institute" as Graetz and Wiitanen were living in a tenement building on Hingham Street in Cambridge, Massachusetts.
Not a very good demonstration. Here was this display that could do all sorts of good things! So we started talking about it, figuring what would be interesting displays.
We decided that probably you could make a two-dimensional maneuvering sort of thing, and decided that naturally the obvious thing to do was spaceships.
The gameplay of Spacewar! The ships have a limited number of torpedoes and supply of fuel, which is used when the player fires the ship's thrusters.
The ships remain in motion even when the player is not accelerating, and rotating the ships does not change the direction of their motion, 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 or the opposing ship. 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 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 it disappears for a few seconds, but the reentry from hyperspace occurs at a random location, and in some versions 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. The location of the switches also left one player off to one side of the CRT display due to the limited space in front of the computer, which left them at a disadvantage.
The button was silent so that the opposing player would not have a warning that the player was attempting to fire a torpedo during a cooldown period.
See below for details. For some other interactive programs running on this emulator, see www. Single-key actions may also be useful for custom joystick mappings.
Some keyboards may not read all keys at once, please resort to the alternate fire keys "4" and "0" in this case. Some gamepads may require special connection modes like switching them to "direct mode" or having a connection button pressed, when plugging in.
Digital sticks and D-pads are supported as well. Any major button should work as fire. Left shoulder buttons are hyperspace, right shoulder is fire.
Hit the tab-key of the keyboard to swap the assignment of pads and ships. Click here for an illustration of gamepad mappings. Touch Controls: Special controls featuring arcade-style buttons are displayed for touch-enabled devices use landscape orientation; drag the controls by their ship icons to move them to a convenient screen location.
The emulation is running various versions of the original game, both from binaries copies of the original paper tapes and newly assembled from authentic code listings.
Further, there are both earlier and later versions, as Spacewar! Graetz and some examples of version 4 adding minor features and compatibility to an upgraded hardware.
Finally, there is a special version of Spacewar 3. Please mind that the title screens are generated by the emulator and are not part of the original games.
Versions available by the "versions menu" at the top left of the emulated display :. In the original game, the game halts at the end of a match which may be set up for a spefic number of games by console switches not implemented in this emulation and scores are displayed in binary using the console lights for the accumulator and the IO-register.
For these games the emulation tries to detect the scoring code and displays the AC and IO lights along with scores presented as decimal numbers below the virtual scope.
Some later versions of the game, like 4. Here, scores are displayed at the end of each game. Alternatively, you may access the scoring option by the options menu.
If scoring is deactivated, when leaving the score display, scores are reset to zero. Some research has been invested in order to identify various versions and paper tapes, some of these versions are here playable for the first time in decades.
The locations of the individual sources are linked in the descriptions above. Versions marked "[bin]" are loaded as-is from binary paper-tape images as they are found in the archives.
Versions marked "[rim]" were newly assembled for this emulation from historic source listings. Modules marked "[mod]" are modified versions based on genuine listings.
You might want to play in classic setup with the "Sun" killing on contact by activating sense switch 5 see the options menu at the top right of the screen.
Realtime time-keeping was added for authentic emulation speed based on cycle counts. Aside the support of the PDP-1's sense switches to control some of the games' behavior, there's also a provision to extract and hack essential constants setup parameters of the games see the tools menu accessible by the options menu at the top right of the screen.
It featured a clock rate of 0. The standard memory was 4 K of bit words expandable. The over all performance is roughly comparable to the one of an Apple II micro computer from the late s wider words and less CPU cycles per instruction make up for a slower clock rate.
Some importance has been put in reconstructing the visual impression of the original CRT display:.
The make of the tube was originally intended for radar scopes and employed a dual P7 coating with two layers of phosphor, a bright, light-blue one displaying freeshly activated blips, and a dimmer, greenish-yellowish one displaying the decaying blips in a fading afterglow.
These characteris are also responsible for the iconic trails drawn by any moving object on the screen. The Type 30 CRT was essentially a point plotting device also known as XY display , meaning that there was no memory or repetitive scan, but plotting locations were addressed randomly by individual display commands.
Refreshing the screen was entirely left to the program, which had to redraw any blips that were to stay on the screen.
If not refreshed, the blips would fade away in the afterglow of the P7 phosphor. The spot size of an activated location increased with its intensity the display featured 8 distinctive brightnesses , the blips — we cannot speak of pixels here — thus slightly overlapped and mended on the screen, effecting in a visible resolution of approximately by display locations.
It lacked any memory, but it was a serious piece of hardware that came at a destinctive price tag. Point plotting CRTs with P7 phosphor are also known as "animated display" or "painted display" for their sponge-like display characteristics.
These characteristics are quite important for the game, since its drawing mechanism heavily depends on the afterglow of the display, which provides the required stability for the screen image.
Moreover, since the built-in brightnesses didn't scale that well, perceivable brightnesses are also modulated by distinctive refresh rates.
The emulation recreates the distinctive characteristics and their effects, like the dual layers of phosphor, the variable intensities and spot sizes, and the overall perceptible resolution.
In low-resolution mode a special virutal subpixel mapping is employed to boost the display resolution, providing smooth movements and a similar degree of visible detail like the original device.
Thanks to the faithful recreation of the display, the programs can be run and displayed at the original frame rate by the emulator. There's also an option in the settings dialog to opt out of true frame-by-frame rendering for a more stable, flicker-free display.
While the low-resolution mode corresponds closely to the visual impression of the original display, users provided with a large screen or a high density ["retina"] display, may want to also check the full-scale version of the emulator.
The two ships navigating in outer space are subject to the gravity excerted by a central star, closely simulating the laws of Newtonian physics.
Photon torpedoes of limited supply not affected by gravity themselves for the limited resources of the PDP-1 may be fired in order to destroy the opponent.
