Hi,

in 1996/97, I have done my diploma on Neural Networks (Backpropagation). The result was a small simulator program to be found here:

I have opened (GPL) sources in 2000 (didn't know about that possibility before). The program was written using Delphi 2.0 (ObjectPascal).

Perhaps you can still find some useful things there. I don't continue to develop on the project as my interest is now Medical Software
(http://www.resmedicinae.org). Just found NLP by chance on SF. So I'm afraid I can't give support being busy also in my profession. However, if you have minor questions (but 5 years is a long time!), just email me directly:

Best wishes for all your Neural Network projects,
Christian
