Core War: Imps, Imp Rings and Imp Spirals
Imp is the simplest example of a Redcode program that is able to relocate itself in the memory array. It copies the contents of relative address 0 (namely the Imp) to relative address 1, the next address. As the program is executed it moves through the array at a speed of one address per cycle, leaving behind a trail of Imps.”

Core War - Computer Recreations articles by A. K. Dewdney
A. K. Dewdney is a computer scientist, mathematician, and author. Dewdney introduced Core War in his first Computer Recreations column in Scientific American, May 1984. Follow-up articles were published in March 1985, January 1987, and March 1989. The Core War columns were collected in two anthologies, The Armchair Universe and The Magic Machine. Translations were also published in the international editions of Scientific American.

50 YEARS AGO IN COMPUTING HISTORY 1968 - Michael Bennett visited DEC where he discovered the programming game Core War. Dr Bennett set up his own version when he returned to the University of Western Ontario, inspiring A K Dewdney to create modern Core War

Early History of Core War
When A K Dewdney introduced Core War in 1984 the name had already been used for similar games for a number of years. These early versions of Core War were played in the assembly language of the host computer similar to Darwin. Unfortunately very little has been published about early Core War.
