Could you please post the following?  Thank you,  Bruce Shriver

This note is being separately posted on the following bulletin
boards:

  connectionists
  neuron-digest
  neutran

Please recommend other bulletin boards that you think are also
appropriate.
===============================================================

I am interested in learning what experiences people have had using
neural network chips.  In an article that Colin Johnson did for PC
AI's January/February 1990 issue, he listed the information given
below about a number of NN chips (I've rearranged it in
alphabetical order by company name).  This list is undoubtedly
incomplete (no efforts at universities and industrial research
laboratories are listed, for example) and may have inaccuracies in
it.

Such a list would be more useful if it would contain the name,
address, phone number, FAX number, and electronic mail address of
a contact person at each company would be identified. 

Information about the hardware and software support (interface and
coprocessor boards, prototype development kits, simulators,
development software, etc.) is missing.

Additionally, pointers to researchers who are planning to or have
actually been using these or similar chips would be extremely
useful. I am interested in finding out the range of intended
applications.

Could you please send me:

  a) updates and corrections to the list
  b) company contact information
  c) hardware and software support information
  d) information about plans to use or experiences with having used 
     any of these chips (or chips that are not listed)

In a few weeks, if I get a sufficient response, I will resubmit an
enhanced listing of this information to the bulletin boards to
which I originally sent this note.   Thanks,
