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.

ForthOS was the basis for the author's own experimental software work; unlike many other Forth systems, this one as a real tool in day-to-day use as a part of a larger development. It is a fully standalone system, with a metacompiler used to generate new versions of ForthOS while running under ForthOS. Please read about its legal status; the short version is that ForthOS is in the public domain.

ForthOS supports:

The current version is ForthOS 1.0. Please read about the installation here.

Actually, the last great copy of ForthOS development can be found here. There are bootable bits, and also a filesystem with all of the source.

There are some very old utilities which might help with the block files.

A private newsgroup server existed for a while to permit communication among interested ForthOS users; a read-only archive of it is here.
