As you learn Forth, it learns from you (1981)

1. factor

   1 63 1,665 9.9 Factor

   Factor programming language

   

   I think jonesforth is the most popular implementation teaching implementation: https://github.com/nornagon/jonesforth/blob/master/jonesfort...

   Factor might be a counterexample if one considers it a Forth, the VM is in part implemented in C++: https://github.com/factor/factor

   I think it's portability and ease of development rather than CPU architecture complexity that makes someone pick C/C++ over assembly when implementing a Forth system. Because the Forth won't need much of the assembly language or obscure CPU instructions, the complexity of the architecture won't really matter to whoever is implementing it.

   Mitch Bradley's CForth implementation

   Mitch Bradley was the author of a great deal of that Forth; his CForth is on GitHub : https://github.com/MitchBradley/cforth

   (It might be easier than finding an old Sun machine)
