Unfortunately, by the time I had a home computer (1986) I no longer had a copy of my paper (not a significant loss. really) or the source code for the program.

You can find sources, a compiled version for RSX, and play around with 
the whole thing on MIM. There is also a second version, written in 
Fortran in that directory.

Telnet to mim.stupi.net, login as guest, change directory to US:[CHESS] 
and have fun.
