It is easy to ask for a copyright release from the owner (if they are still in business.) I got permission from Motorola to uses some data sheets on my web site. http://www.swtpc.com/mholley/MP_A2/MC6875/MC6875.htm I sent an email to the press contact in the semiconductor division. (See my request below.) I asked them to foward my request to the correct department. I was emailed a short form to fill out and then they gave me permission. I did the same for Byte magazine but received no response. I am going to put some Radio Electronics articles up without permission because Gernsback Publications went out of business last year. If I find out who owns the copyright I will ask for a release. Try to locate the owner and keep a record of your effort. Have contact information on your web site so any copyright owner can reach you. Heathkit is still around. www.heathkit.com Ask them for permission. I think Popular Electronics was acquired by Gernsback Publications. Michael Holley www.swtpc.com/mholley --------------------------------------------------- My original request to Motorola I have a non-profit web site that documents personal computers from the 1970s that were based on the Motorola 6800 family of microprocessors. ( www.swtpc.com/mholley ) I would like permission to post copies of out-of-print Motorola data sheets. These are useful for collectors and hobbyist who are restoring these 6800 based computers and games. An example is the datasheet for the MC6875 clock generator. http://www.swtpc.com/mholley/MP_A2/MC6875/MC6875.htm Could you direct this email to the correct person that handles this type of release? ----------------------------------------------------
