Mini-Scheme history

Mini-Scheme (which goes by the filenames minischeme and miniscm) is at once one of the tiniest and earliest Scheme implementations. Its obscure beginnings and the several independent forks started in the decades since have led to a confusing family tree which this page tries to untangle.

Original versions from Japan

The original author of Mini-Scheme is mathematician Atsushi Moriwaki from Kyoto University. After he stopped working on the program, his compatriot Akira Kida maintained it for five years.

Information about these early versions is found in the README file of version 0.85k4. The file says the program is based on an article SCHEME Interpreter in Common Lisp which was published in Japan as an appendix of T. Matsuda & K. Saigo, Programming of LISP, archive No 5 (1987) p6 - p42.

TinyScheme

The well-known implementation TinyScheme started off as a Mini-Scheme fork but has been refactored and extended so much that the name was changed.

Archival

Releases of the various Mini-Scheme forks are archived at files.scheme.org using a file naming convention which includes the maintainer's handle as well as a version number or release date.
