LispOS Info Page Brief history, and link to mail list archive, begun April 1997, closed February 1999, by Richard Coleman (of ZSH), to coordinate efforts to make a free OS to return to users the power of Lisp Machines.
Lisp-based OSes History, considerations for operation, list of projects with links (some updated, some not).
NASOS: Not Another Scheme Operating System Ideas, wish list on how to build Scheme OS to run on cheap PC hardware, and some platforms that may succeed it. Intended to be mildly radical yet doable.
FunOS Mostly functional (programming) OS in design, and fun to do system programming in; all policy code in kernel to be in Scheme. To support multiple APIs, and be runtime extensible: replace parts of system on the fly and, within security constraints, by ordinary users.
