Welcome! Retro is a small, minimalistic dialect of Forth. The Retro language has a rich history going back to 1998 when it was first released as a 16-bit standalone Forth for x86 PC's. Since then it's evolved through use into its present form, which is a 32-bit implementation running on a portable virtual machine called Ngaro. Today Retro runs on all major operating systems, and thanks to a JavaScript implementation of the virtual machine, on any modern web browser. The code and documentation for Retro are gifted to the public domain. You may use them freely and without restriction. Mailing List Questions, comments, need help?
