King Edward

The King Edward game authoring system was created by programmer James Terry in the mid-1980s. It was produced in the programming language FORTH in a version, according to Terry, called “Atila,” originally produced for the Apple II. Terry later “ported” the system to the Commodore 64 and the IBM PC. He reports that FORTH was written in 6502 on the Apple II and 8086 assembler on the IBM PC (Terry). The only other game built with this authoring system is the unpublished Jim Henson's Fraggle Rock, which was completed but dropped by the original publisher, Harper and Row, after Henson could never come to a satisfactory agreement with another publisher.
