I was strongly considering writing a Forth implementation designed to run bare-metal on a Raspberry Pi, that is, booting directly into Forth with no OS. I thought this might be of interest to the community both for educational reasons and probably nostalgic ones as well.
However, I feel like this is something that should have been done already. Is there anything like this that's been done already? If there's an existing project along these lines, I'd rather contribute to that than start all over.
I've also considered the BeagleBoard as a target for this, so any information on projects for that would also be nice.
