With great help here and in the Fou Numerique forum, I've been able to collect all competitive engines up to the year 2000 for my "Dinosaur League". I've just put my first results in the tournament section of the forum.
Now I am wondering if I could go back up to 1999. I think I am missing only these four engines :
Bringer 1.5
ExChess 3.09
KnightX 1.50
ZChess 1.2 (i am not sure about this one, is that the last version freely availabe at the end of 1999 ?)
Many thanks if someone has these engines and can send them to me :
it was only 7 years ago

Edit : of course that if you are yourself looking for some other old free engines, please ask.
