Moore's personal programming system, which had been in continuous development since 1968.
Forth was first exposed to other programmers in the early 1970s, starting with Elizabeth Rather at the United States National Radio Astronomy Observatory (NRAO).
For example, Forth was the first resident software on the new Intel 8086 chip in 1978 and MacFORTH was the first resident development system for the 128K Macintosh in 1984. Atari, Inc.
MicroFORTH was later used by hobbyists to generate Forth systems for other architectures, such as the 6502 in 1978.
Common practice was codified in the de facto standards FORTH-79 and FORTH-83 in the years 1979 and 1983, respectively.
Two home computer games from Electronic Arts, published in the 1980s, were written in Forth: Worms? (1983) and Starflight (1986). The Canon Cat (1987) uses Forth for its system programming. Rockwell produced single-chip microcomputers with resident Forth kernels, the R65F11 and R65F12.
These standards were unified by ANSI in 1994, commonly referred to as Forth. Forth became popular in the early 1980s because it was well suited to the limited memory of microcomputers.

The bestselling 1986 computer game Starflight, from Electronic Arts, was written with a custom Forth.
Using IMMEDIATE and POSTPONE, [CHAR] could have been defined like this: [CHAR] CHAR POSTPONE LITERAL ; IMMEDIATE === A complete RC4 cipher program === In 1987, Ron Rivest developed the RC4 cipher-system for RSA Data Security, Inc.

Insoft GraFORTH is a version of Forth with graphics extensions for the Apple II. As of 2018, the source for the original 1130 version of FORTH has been recovered, and is now being updated to run on a restored or emulated 1130 system. ==Programmer's perspective== Forth relies on explicit use of a data stack and reverse Polish notation which is commonly used in calculators from Hewlett-Packard.
