| 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 is the original version! Martin Graetz provided us with a printed | |
| version of the source. We typed in in again - it was about 40 pages | |
| long - and re-assembled it with a PDP-1 assembler written in PERL. The | |
| resulting binary runs on a PDP-1 emulator written as a Java applet. | |
| The code is extremely faithful to the original. There are only two | |
| changes. 1)The spaceships have been made bigger and 2) The overall | |
| timing has been special cased to deal with varying machine speeds. | |
| The sources are available in a subdirectory called "sources". | |
| The "a", "s", "d", "f" keys control one of the spaceships. The "k", | |
| "l", ";", "'" keys control the other. The controls are spin one way, | |
| spin the other, thrust, and fire. | |
