Neat. The more, the merrier.

If anyone wants to work through SICP in the original way, you can get MIT Scheme, and run it on some computers.

sudo apt install mit-scheme

Some of us added support to DrRacket, for working through SICP that way (though if you already know how to use an editor, etc., you might prefer to just run MIT Scheme): https://docs.racket-lang.org/sicp-manual/
