Information on Mach licensing and distribution and technical reports can be obtained by writing to: Mach Project c/o Rick Rashid School of Computer Science Carnegie Mellon University Pittsburgh, PA 15213 or mach@cs.cmu.edu Current commercial products I am aware of are from NeXT, Encore, Evans&Sutherland and BBN. Mt Xinu has announced that it will be distributing commercial versions of Mach on several architectures beginning early next year (in much the way it has distributed BSD Unix). CMU distributes Mach for the VAX, Sun 3 and IBM RT architectures. Information on specific models, etc. can be obtained with the general Mach information packet. The current release is referred to as Mach Release 2. We are about to begin general distribution of Mach Release 2.5 (a number of Universities and companies already have early releases of 2.5). There is a license for Mach from CMU and you will need a Berkeley license to get a tape from us. There is no distribution or license fee paid to CMU, however. At CMU Mach runs on VAXen (uni and multiprocessors), DEC 3100s, Multimaxes, Sun 3s, Sun 4s, 386s, IBM RTs, IBM 370s and Macintosh IIs. Ports have also been done to a number of other machines by groups outside CMU. CMU has limited capacity to distribute software so we don't distribute Mach for all systems. We are, however, willing to provide Mach free to any manufacturer who is interested in distributing it for their own machines. If you want Mach for a machine for which there is a port but no current distributor, you should talk to your salesman or corporate representative. I should also point out that CMU maintains a mailing list for information about Mach. You can get on this list by sending mail to info-mach-request@cs.cmu.edu. The list itself is info-mach@cs.cmu.edu. An interface for external management of multiprocessor scheduling was the most recent topic on that list. -Rick Rashid
