Hi, Please forgive me if this OSI document is already on the web somewhere. I looked but couldn't find it. I have a copy so I scanned it. It can be downloaded at: http://www.classic-computers.org.nz/blog/2016-12-25-OSI-CP1-technical-report.htm Feel free to link to it, or place it in other OSI repositories. Merry Xmas Tez
