Ancient olithink fossils
Found them on my old chess analysis project backup CD.
I have some more somewhere, but it might take a while to find them.
Oldest one is Olithink 2.2.1 from 20 years ago.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Ancient OliThink fossils.
Hello Dann:
Thanks to the CPW article and an old archived post from the CCC, I found the URL of OliThink of those days and let the WayBack Machine to do its magic:
http://www.phy.uni-bayreuth.de/~btp434/
http://web.archive.org/*/http://www.phy ... e/~btp434/
http://web.archive.org/*/http://www.phy ... /~btp434/*
The last link lists the items that are still reachable. The source code of version 2.0s is still downloadable!
http://web.archive.org/web/199902200642 ... lisuic.tgz
The files of the source code are from April, 1998. Some of the *.c and *.h files have _s suffix, probably noting 2.0s version instead of 2.0, opposite to the file names written in the Readme file. One way or another: enjoy!
Regards from Spain.
