LispOS on a 68000

    How feasible would a Lisp/Scheme OS be on a 68000?

    Please realize that I am in question-asking-mode here. I have no
    idea how Lisp internals are implemented. I am thinking about putting
    together a homebrew 68000 or 68030 and it would be nice to run
    something besides Forth on it. My concerns are:

        a. Speed - If I wirewrap it, I will be stuck to around 8-10MHz.
           Not exactly blazing. If I use a 68030, I will probably knock
           out a couple PCBs for it and speed won't be quite so much an

        b. Implementation - I don't know enough about Lisp to actually make
           my own (not a pretty one, anyway). I could probably hack together
           some Lisp/Scheme looking thing, but that wouldn't be quite the same.

    Thoughts? Has this road been covered before? I would probably just
    communicate with it by way of serial at first; a nice bitmapped display
    wouldn't be too hard though.
