The Association will continue to maintain the non-profit price of $200, as was charged by the CSRG. The release will consist of two 2400 ft., 1600 bpi tapes (approximately 80M) and approximately 100 pages of documentation. If you require 800 bpi tapes, please contact USENIX for more information.

Note: The BSD history is strage; 2.xBSD had a long life parallell to 4.xBSD; 2.10BSD is in part based on 4.3BSD.
