Some weeks ago I posted the following question to this newsgroup:

`` Are there any chips supporting the concept of neural networks? ''

I want to thank the people who devoted a piece of their precious
time to answer me.

Below is a list of the responses that I recieved. I have removed
some text, including the various disclaimers; therefore please
note that the different people are talking on behalf of themselves.
I would like to appologize if I have forgotten anybody.

I received an email from Siang-Chun The, which stated pretty much the
same as this posting. I chose to bring the posting.
