This wiki remains, like the original forum, mainly for historical value. There is a new wiki which, while having less content, is more secure and oriented towards modern Retro implementations.

RetroForth is a lightweight, easy to learn, and complete implementation of the Forth programming language. It is provided freely and has a very active community accessible by a forum, wiki, irc at irc.freenode.net#retro, and a low volume mailing list.

There are plenty of full-featured Forth compilers, e.g. IsForth, BigForth, Win32forth, Gforth, and the commercial Forths

RetroForth [since version 3] is modeled after cmForth, Colorforth, Eforth and Pygmy. It uses some, but not all, of Chuck Moore's newer ideas. It's clean, elegant, and tiny - only about 20k source/10k binary for Linux. It may not have many features, and it may not be particularly useful by itself, but it's easy to grasp, easily adapted to various uses - even on other CPU architectures. I think that's our niche.
