Symbolics Lisp Machines -- http://smbx.org/ (The Symbolics Museum). Microcode and processor support for Lisp primitives, all operating system code and development tools written in Zetalisp. I used them for a couple of years in the late eighties at the GE R&D center in upstate NY. Whether it should have been done is another issue :-) I actually liked using the machines, but given the limited market, the company was doomed. While the special-purpose hardware was somewhat faster than the general purpose hardware at the time, it was horrendously expensive, and the Sun 3's we replaced them with wer a lot more useful, and almost as fast running Common Lisp as the Symbolics machines wer running Zetalisp.
