Mapper originated in the 1970s[1] based on some work in the 1960s,[2] It has been functionally enhanced and kept current. It was also given an extension named ICE - Internet Commerce Enabler.[3][1]
Originally available on Sperry's Univac 1108, implementations now also exist for Windows NT, Sun Solaris and Linux.[4] The GUI on Windows is the most advanced of these.[1]
