I'd built a device with an MSP430 and have been meaning to try CamelForth on it instead of using my own C code.

I'd be curious to try something else for easier testing at a higher level or even figure out how to run the 8086 in a virtual machine..

>> but GForth, the only accessible Forth, looks a bit unloved.

With something as stable as Forth, I'm not sure what kind of activity would indicate a project is active enough unless it is adapting to new or highly unstable architectures?
