  Hi There,


    Computer Vendors Directory was formed in 1983 to provide the computer
  world with information about the Computer Industry.  We feel we have the
  most up to date information available.
    We operate completely off donations.  This is only a small sample of the
  235,000 Computer Manufacture(s) we keep track of.
    YOUR DONATION IS VERY IMPORTANT!!!.  We need any amount. It's getting
  pretty bad you guys.  This is got to stop.  We don't belong to ANY
  SHAREWARE Software Association (Mainly we have never been asked since 1983).
    We register the software we use.  Do you use our list?  What is it worth?
  Please send anything you can.  We need it.
    I have been a SYSOP of one of the first bbs's in the country.  If this is
  the type of contributions developers of Shareware get?  Then it is not
  worth us to help you, IS IT!
    If we don't get some funds, this will be the end to this public domain
  version after 10 years of helping you.  All donations over $25.00 the
  person will receive all the information listed below on the companies that
  have been verified in the last year (90,000 est.) plus any updates free,
  just send the original diskettes back for the update.
    If you are an manufacturer of a computer product, we need more
  equipment (not for resale equipment).  Mainly hard disks (USED or NEW
  with controllers) any size will be welcomed.  In return we will provide
  you with any information that you may need. Plus name recognition like
  the US Robotics Modem we use to upload and to run our bbs.
    We are not a mailing list company.  We provide information to companies
  who do research/marketing who are looking for a product(s).

                The information that we keep track of is:
   Company Name - Mailing Address - Street Address - Division or Owned by -
  City - Zip - State or Country - Phone# - Fax# - 800# - BBS# - Tech
  Support# - Telex # - Number of Years in Business - Number of Employee(s)
  - Annual Income - CEO/President - Marketing Rep. - Sales Mgr. - Stock
  Code - Means of Distribution - (5) Market Speciality(s) - Plus a fifty
  word description of the product(s) that they market or manufacture, per
  Market Speciality.

  If you feel you get good use the information from us. Then please
  consider a donation.
