THIS DOCUMENT MUST ALWAYS BE INCLUDED IF YOU REDISTRIBUTE, IN WHOLE OR IN PART, ANY OF THESE MIX CP/M COMPILERS AND ASSOCIATED FILES THAT ORIGINATE FROM MY WEBSITE OR FROM ME. Bill Buckels December 2008 Permission for use Re: MIX C for CP/M Z-80 ------------------------------------------ On December 13, 2008 I sent a permission request to Dennis Saunders of Mix Software, Inc. to make their decomissioned CP/M C compilers available for use and distribution by hobbyists. Dennis responded with his permission. The text of those messages is shown below. Below that are my own conditions of use for any of these MIX CP/M compilers and associated files that originate from my website or from me. I have used Mix Software, Inc.'s end user license for their C Database Toolchest as a guideline for my own conditions of use: http://www.mixsoftware.com/product/db/license.html Mix Software's compilers are not in the Public Domain. The CP/M versions have been decommissioned and are no longer available for purchase nor are they supported. Regardless, Mix Software, Inc. is still the owner of these compilers and has the sole right to grant licenses. Exhibit A - Permission Request ------------------------------ From: Bill Buckels To: Dennis Saunders Sent: Saturday, December 13, 2008 Subject: Request for Permission Re: MIX C for CP/M Z-80 Hi Dennis, Please forgive the further intrusion. If Mix Software has no further interest in their CP/M 80 compilers is it possible to release them to the Public Domain or grant a limited distribution licence to hobbyists to use and redistribute user copies of the CP/M 80 version. An email from you would probably suffice as permission and disclaimer of liability. This would be of interest to a very tiny segment of the online retro- computing community. I would not hesitate to register a domain called mixsoftwaremuseum or similar and formally maintain an archive with no need from you for further involvment of any kind or to simply make the compilers available from the http://www.cpm8680.com/ domain. All the best, Bill Buckels Exhibit B - Permission ---------------------- From: Dennis Saunders To: Bill Buckels Sent: Saturday, December 13, 2008 Subject: Re: Request for Permission Re: MIX C for CP/M Z-80 Bill, You have our permission to make the CP/M version of the compiler available to whoever wants to use it. Sincerely, Dennis Saunders http://www.mixsoftware.com Conditions of Use ----------------- The above email provides limited assignment rights on behalf of Mix Software, Inc. to make their decomissioned CP/M C compilers available for you to use. You can use these compilers to produce and distribute applications, and you can distribute application source code and documentation with no royalty obligation so long as the applications produced do not compete with the current Software offered by Mix Software, Inc. as a development tool. You can also give these decomissioned compilers to other individuals providing those other individuals agree to all the conditions of use in this document and have read and are in agreement with the disclaimer in this document.
