PDP-1 online emulator with Spacewar
|Spaceship 1:||Key:||Spaceship 2:||Key:|
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.
This is the original version! Emulator and Spacewar conversion made by Barry Silverman,
Brian Silverman, Vadim Gerasimov. They got the original source from Martin Graetz in a print which they typed in again and
and re-assembled it with a PDP-1 assembler written in PERL. The code is almost the original
only two small changes have been made (bigger spaceships + timing for dealing with varying machine speeds).
