The full story
Mitch Bradley and Claude wrote a Forth for the PDP-7, the 18-bit machine the first version of Unix was written on, in one day. A Hacker News commenter calls it high quality, efficient and beautifully commented. The PDP-7's instruction set turns out to suit Forth perfectly: the inner interpreter is only three instructions, starting with an "execute indirect", giving a threading model unique to this machine.
