"In ships or on broomsticks — (...) we'll burn them out of the ether!", E.E. "Doc" Smith, Triplanetary.
Spacewar! was conceived in 1961 by Martin Graetz, Stephen Russell, and Wayne Wiitanen. It was first realized on the PDP-1 in 1962 by Stephen Russell, Peter Samson, Dan Edwards, and Martin Graetz, together with Alan Kotok, Steve Piner, and Robert A Saunders. – Spacewar! is in the public domain, but this credit paragraph must accompany all distributed versions of the program.
This implementation by Norbert Landsteiner, www.masswerk.at, 2012-2015.
Added enhanced, CRT-like graphics, support for variable output sizes, a splash-screen with near to authentic graphics, and embedding artwork. This implementation also features changes to the original emulation code, some additional instructions, and additional emulated hardware. Also, there are multiple versions of the original code ready to play.
Touch-Controls — With touch devices use landscape orientation. Use the ship icons to move the controls to a convenient location.
