In case you wonder how froggey managed to obtain a Common Lisp version of Quake, have a look at https://github.com/froggey/Iota.

Since the demise Lisp machines, there have been several attempts at developing a Lisp-based operating system which didn't deliver anything: LispOS, Tunes, and Loper; and one successful attempt at getting Lisp to run on the bare metal: Movitz. Lisp was its own operating system on the original Lisp machines developed at MIT, and this evolved into Genera at Symbolics. Is this the case here? I notice that Mezzano has files. Files are inherited from operating systems running non…
