It's prototype hardware and it's not intended as an open source software project. It is therefore not going to be released to the general public. When it's finished, and it isn't at the moment, it's hopefully going to be part of your future processors. I did however find a enormous lot of bugs (in the kernel, the compiler, and in latex) since the project start, that deserve the attention of the opensource community. The bugs will come available to you in time. We can work on a better kernel and compiler together. > > I'd hoped you could remove normal floppy disc support instead.

Are you asking to be removed? I'm afraid I don't quite understand. Regards, Mischa.
