This distribution is for VAX\(dg users with UNIX/32V\(dd .FS \(ddUNIX and UNIX/32V are trademarks of Bell Laboratories. .FE .FS \(dgVAX is a trademark of Digital Equipment Corporation .FE licenses and supersedes the Third Berkeley Distribution made in January 1980. The contents of this distribution are described in the two enclosed documents, ``Berkeley Software for UNIX on the VAX'' and ``Changes in the VAX system for the Fourth Berkeley Distribution''. .PP This new distribution is being licensed by a liberalized licensing agreement which eliminates paperwork for additional processors, provides for sublicensing, and is intended to eliminate many potential difficulties with the previous agreement. A copy of the new agreement is enclosed as well as a sheet explaining some special cases. .PP The Computer Systems Research Group (CSRG) at Berkeley has recently been funded by the Defense Advanced Research Projects Agency (DARPA) to develop additional enhancements to the Berkeley version of UNIX. It is anticipated that any system developed for DARPA will be made available using a mechanism similar to that used for 4BSD. A short description of this project is enclosed. .PP The distribution consists of a magnetic tape plus printed documentation. The magnetic tape contains copies of all binaries, source code, and documentation. The printed documentation contains a complete manual set including both the Berkeley documentation and material which is unchanged from the original Western distribution. In addition, a high-quality one-sided typeset duplication master is provided for volume one of the UNIX Programmer's Manual and for the sections of volume two which originate at Berkeley. .PP To receive the distribution, send two executed copies of the license agreement, a .I check for $300 U.S. payable to the ``Regents of the University of California,'' a copy of your UNIX/32V license agreement, and a filled out copy of the enclosed ``Configuration Description Form'' to .DS Laura Tong, Distribution Coordinator Computer Systems Research Group Computer Science Division, EECS University of California Berkeley, CA 94720 .DE .PP We will return a fully executed copy of the agreement to you with the distribution. .PP If you have questions about the distribution or the licensing process, contact Laura Tong at the above address, phone her at (415) 642-7780, or send mail over the ARPANET to csrg@berkeley. .sp .ti +3.5i Sincerely yours, .sp 2 .ti +3.5i Professor Robert S.
