Don Peterson D.B.A. Data Professionals





Why was my auction cancelled?

In October 2008, Data Professionals of Pleasanton California purchased the Copyrights and existing inventory of all of the legacy Heathkit Product Manuals, with full rights, title, and interest.  This includes, but is not limited to, the individual pages of the manuals, the schematics, and portions of any manual, illustration booklets, and most other literature that was originally copyrighted by Heathkit Company and/or Heath Company when they were independant and/or a subsidiary of Daystrom, Schlumberger, and Zenith.

While in the past, Heathkit had little or no interrest in monitoring any infringement against their copyrights, as the new owner, this is our only source of income.  Data Professionals has a legal responsibility to enforce its copyrights and property rights against unauthorized duplication and distribution to protect our good name and intellectual property rights.  To that end, we monitor the Internet, including auction sites.  If there is a violation of our intellectual property rights, we will request eBay to cancel the auction.  If the auction is cancelled by us, the notice will provide our contact information.  If you need to report a situation you believe should be brought to our attention, please contact us at

As a seller, you have a responsibility to ensure that your actions do not violate the intellectual property rights of others.  Ignorance that your auction is a violation of any country's trademark, patent or copyright law is no excuse.

For information on manuals, or repair parts required for legacy Heathkit products, please visit our web site at, or see our eBay store under DataPro on the eBay site.
