The emulator for the MIT Lisp Machine doesn't take hours to boot and it seems to run stuff at similar speeds to the real hardware. I would suggest that anyone contemplating a new system take a really good look at how the MIT Lisp Machine was implemented, maybe look at the K-Machine sources afterwards for a possible way of using native code.
