LispOS

LispOS was a project to revive the still unequalled systems that ran on Lisp Machines of the past (such as the still surviving Genera) this time making it free and running on standard/cheap hardware, instead of proprietary and requiring non-standard/expensive hardware. But there were too many divergent opinions, and no team really built up. Notable issues of contentions were on which LISP to use (mostly CL vs Scheme vs some new LISP), and what flavor to give to the OS (clone of old LISP OSes, kind of better-UNIX-in-LISP, or a new orthogonally persistent system). Still, a lot of interesting information can be gathered from the (now closed, but archived) mailing-lists that were created, LispOS and LispVM.
