ForthOS is a complete, standalone operating system for the PC.
It includes command line, compiler, debugger, editor, and filesystem.
You can give it a test drive by booting the standalone CD (image
provided so you can burn your own). If you like it, you can install
it onto a disk partition and boot directly from your hard disk.
