In the early 1970s, Spacewar! migrated from large computer systems to a commercial setting as it formed the basis for the first two coin-operated video games.
Byte magazine published an assembly language version of Spacewar! in 1977 that ran on the Altair 8800 and other Intel 8080-based microcomputers using an oscilloscope as the graphical display and a lookup table to approximate the calculations for orbits, as well as a three-dimensional variant in 1979 written in Tiny BASIC.
