This is what you want, I guess: https://docs.racket-lang.org/sicp-manual/index.html https://pkgs.racket-lang.org/package/sicp Trying to run the original language from the times of original publishing on contemporary systems is just a needless hassle. ...just some rabbit from a hole in some forum ;-) edit: It's also not dead and linkrotten, as can be seen here: https://github.com/sicp-lang/sicp addit: also from your favourite forum: https://news.ycombinator.com/item?id=25442005

It's actually easy to implement that slight variation in Racket, as a `#lang` or reader extension. As an example of a Scheme-ish `#lang`, here's a Racket `#lang sicp` that I made to mimic MIT Scheme, as well as add a few things needed for SICP: https://github.com/sicp-lang/sicp/blob/master/sicp/main.rkt It would be even easier to make a `#lang better-scheme`, by defining just a few changes relative to `racket-base`, such as how numbers are read.

Note that there is a new implementation of Hendersons's picture language. Color images is just one of the new features. Save this file. Open it. Either add your own code at the bottom or use require to use it from another file. https://github.com/sicp-lang/sicp/blob/master/sicp-pict2/sic...
