“PDP-1 Computer and Spacewar”

This is a promotional brochure by the Digital Equipment Corporation (DEC) celebrating Spacewar!, 1963 ca.

The brochure also illustrates the ambiguous position on Spacewar!: While the game was officially banned at some installations (e.g. BBN outlawed Spacewar! occasionally, mainly because of dying control switches), it was also the most important showcase for the PDP-1. Eventually PDP-1s shipped with a copy of Spacewar! in memory for testing purpose. (Since the machine's magnetic core memory was persistent, the program would be present, when the machine was unpacked and switched on — ready for a test run of Spacewar! This wasn't an outrageous claim at all, since the program utilized nearly every resource of the machine.)
