I'm kinda curious about Forth on the Propeller - does most of the interpreter run in the cog, or does it have to dip into main memory a lot?

There are several different Forth implementations for the Propeller chip. Most have a VM run in a cog that creates the basic stack machine, the stacks can be in hub RAM, but I think TachyonForth uses cog RAM and has limits about depth of call. The word definitions and program are always in hub RAM

The Propeller page on Wikipedia says, "There are at least six different versions of Forth, both commercial and open-source software, available for the Propeller."

Naturally this doesn't stop me from wanting to write a Propeller Forth of my own!

Also I'm wondering about a 65xx/Propeller hybrid, similar in some ways to what Jac has done.
