This would be a major development should this come to pass. Even if Genera doesn’t get released under a OSS-compliant license, this will be beneficial for hobbyists and historians (though I don’t know how restrictive non-commercial licenses are for people in academia), similar to the recent release of the Apple Lisa source code (which has similar stipulations). I’ve always wanted to use Symbolics Genera, but I was born around the time of the AI winter of the late 1980s.

I wonder if there were any efforts in the 1990s or 2000s to create a FOSS clone of Genera in the vein of either the GNU project, the Linux kernel, and 4.4BSD and its descendants. I heard that Genera is quite complex, but complexity didn’t stop ReactOS and Haiku from chugging along after all these years.

Not that I know of, but here's an install guide for the real deal: https://archives.loomcom.com/genera/genera-install.html

Also, the predecessor MIT CADR LispM has had an emulator and OS for awhile.

There is also an emulator for the LMI Lisp Machine [1].
