Lisp again

[utzoo!decvax!yale-com!ima!johnl]

Does anybody out there know of a Lisp that could be coerced to run 
on an Onyx?  The Onyx has 64K split I/D so anything written in C 
that runs on an 11/70 is a possibility.  The Harvard Lisp is written 
largely in PDP-11 assembler so it's out.  Franz is also out, it's 
much too big and has lots of in-line VAX assembler.  There was a 
Lisp in C from Princeton a while ago, did anything come of that?
