Hi, I personally saw the F21 running inside a mouse case in 1994 and it was faster than a 486 by much !! The idea of small and fast stack computers is so nice that I do not understand how it never caught up. And the guy that is making the project understands stacks better than anyone else, he invented Forth. I would love to put my hands on that thing and make it rock !
