51-FORTH is an implementation of the Forth programming language for the Intel 8051 microcontroller. It was created in 1989 by Scott Gehmlich of IDACOM Electronics (which was acquired by Hewlett-Packard in 1990), and sent to Giovanni Moretti of Massey University, from whom it was propagated widely.[1] The original 51forth.zip package is available from many archive sites, along with several other implementations of Forth.

This implementation is subroutine-threaded, with about 20 words written in assembly language, and the complete system occupying a total of about 8K of RAM. It was cross-developed from a VAX to an RTX2000 Forth system connected to dual-ported RAM accessible to the microcontroller.

The sources and documentation are in the public domain.
