 Dear Marketing Director:


      Computer Vendors Directory has been formed to facilitate a relation-
  ship between computer dealers and manufactures and to provide information
  on computer-related manufacturers, services and products available in the
  computer industry.
                                          
      The 1992 release 2 of the Computer Vendors Directory is a listing of
  computer oriented manufacturers around the world.  We intend to offer the
  directory to dealers, corporations, and manufactures in June of 1992.
  Your company name, address and phone numbers will be listed in the
  directory. However, specific information on the products and services you
  offer is not yet included.

                                                
      How does the Computer Vendors Directory work?  You, the manufacturer
  will be listed under one or more of 32 product sub-headings in the directory.
  In addition to your basic listing, we would like to expand your listing to
  include a fifty word description of the product or products that your firm
  offers.  Your total cost for the expanded listing is ONLY $10.00 annually
  for each sub-heading under which you wish to have your company information
  and product decriptions to be listed under.

    
      On the following page you will see the different sub-headings
  available.  To have information on your products included in the directory,
  please provide a fifty word description for each sub-headings you wish your
  company to appear (description and product information may vary from
  sub-heading to sub-heading) and return to us together with the $10.00 per
  sub-heading.


     The reason for the $10.00 dollar fee!  We list everyone that we know.  Not
  by convension's or by a certain organizational members.  BUT to offer a
  reasonable priced directory to the people that will use the Computer
  Vendors Directory (Dealers, Corporations, Electronic, Firms, Computer
  Manufactures, etc).   Plus a NEW type of service for faster access to your
  product information.
