Disclaimer for Interlisp Book 1?

the examples on page 283 are unfortunately incompatible with Medley since DEFMACRO for Interlisp was added by using symbol identity (EQ 'CL:DEFMACRO 'IL:DEFMACRO) -- and (EQ 'CL:EQ 'IL:EQ) -- and PUSH and POP were added to Interlisp (before Lyric and Common Lisp)

I think at present we should at least add a disclaimer to the cover of the book that indicates which version of Interlisp it was based on (1984?)
Until we are able to rebuild the IRM from source, can we add the disclaimer to the Documentation page of the project site which links to the IRM?
