I still fail to see how the Racket IDE is inspired by Lisp Machines specifically. Do you have any pointers where this is discussed? What do you think is inspired by some Lisp Machine? REPLs existed before. Editors existed before. IDEs existed before. Lisp IDEs existed before. For example Interlisp had a Lisp IDE in the early 70s, long before it was morphed into something like a Lisp Machine with Interlisp-D.
