Is there any resource you recomend to someone that wants to understand the implementation of these systems? Not the implementation of lisp, but the implementation of these specific environments (lisp machines os's) in lisp. Specially with regards to memory management.

EDIT: you seem to have posted a relevant link in another comment as I wrote this one, but I'd love more information if available.

I am not sure if it will suffice to fully answer the os side, but I mentioned this book in a reply at the top: "The Architecture of Symbolic Computers" by Peter M. Kogge. Amazing book, THE book, at least for me. Written in 1991, it is so fascinating and clear. See if you can get a copy. They seem to have gone up in price this year - from $45 to $250! Lisp is having some sort of renaissance.
