>"Symbolics Lisp Machine demo", special focus on 5 minute onwards. To provide more information since video description lacks, this is OpenGenera a Lisp Machine OS designed to also run hosted on Unix systems. This specific version (seeing it uses jpeg) should be from mid- to late- 90s. Had tried some version but didn't remembered being able to have graphics on REPL. Yes, that's basically how Jupyter console works. But will still argue that the Jupyter model is such weaker version of this that can hardly be called a derivative. Listener isn't only limited to being used like an isolated shell but can be attached to any part of the environment. (And this introspection is core to Lisp and Smalltalks environments.) >Mathematica was inspired from Lisp The language Wolfram, yes. The cell-based notebook interface was new. But similar to previous is a more limited version of what you had available; specifically interchanging text and code in Zmacs. Something that was also an advantage (easier of reason with) for what Mathematica was used for.
