The link takes you to "The Unofficial CP/M Website" who
1. Are the true source of the material.
2. Made it publicly available in in 2002.
3. Have more versions available, e.g. the canonical 2.2.
4. Most importantly, include a memorial for Tim Olmstead, the man who actually negotiated with DR and then painstakingly digitized the documents.
Shame on you, Neil McAllister, for gobbling up a press release and not bothering to do the most basic research.
