The Hurd has never supported anything that doesn't have a coprocessor. > Given that it is now 2005, does anybody see a need today to support > processors earlier than i686 in desktop PCs? I am sure there will be some people shouting "here", but I don't think we need to target these initially. For Hurd-on-L4, we made some decisions early that we would not worry about legacy hardware. When critical mass is reached, people are automatically going to port the software to all kind of weird systems, and there is no way to stop them :) Before that, there is no need, as developers usually will have decent hardware. What is more important for me personally, and I am sure others here, is that we can use free virtualization software like qemu for development. But that shouldn't be a problem, I suppose.
