http://www.theory.physics.ubc.ca/cbw.html http://www.theory.physics.ubc.ca/cbw.html leads to https://github.com/AlbertVeli/cbw https://github.com/AlbertVeli/cbw, which says “This git repository is not meant to improve upon cbw, only make it compile on modern UNIX-like systems, like OS X, FreeBSD and GNU/Linux. Current status: Compiling but crashing. You are welcome to help out ;-)” I didn’t check whether ftp://ftp.isc.org/usenet/comp.sources.unix/volume10/cbw/ still exists. It could have the original sources.
