I am currently reading "The Little Schemer" and I need a way to check the sample circuits in a book on my Windows machine.
What application can I do this with (on Windows, not Linux)?
PLT Schema is a very good standalone Schema development environment available for several platforms, including Windows. It comes with several options for Scheme, an IDE with a debugger and a ton Scheme library for real programming.
There are many circuit implementations. The PLT scheme is good for Windows.
This may work for you.
MIT / GNU Scheme is an implementation of the Scheme programming language, providing an interpreter, compiler, source code debugger, integrated Emacs editor and a large runtime library.
You may not need to install anything on your system. Just click on the following website and you are ready to check out the examples in the book.
