Date: 22 Aug 92 02:10:52 Lines: 47 A free port of the Mach 3.0 micro-kernel to the pc532, a National Semiconductor 32532 based single board computer, is now available. This is a first public version. Improvements are still needed in some areas and bug reports / fixes are most welcome: send them to mach-532-bugs@cs.hut.fi. Also, this is not a complete operating system. A Un*x server is still needed to run application programs. A port of the 4.3BSD emulation along with libraries and user programs has been done and it comes up multi-user but it will not be distributed due to licensing restrictions. A version of the net2 based bnr2ss server has been done but it is not yet in a useful state. (Unfortunately also the freeness of this along with the rest of net2, most of which has been built and ported to the pc532, has been cast in doubt by the Dark Forces). The porting was done at Helsinki University of Technology by Johannes Helander, Tero Kivinen, and Tatu Ylonen as an attempt to obtain some familiarity with the Mach operating system and to get a real operating system for the pc532. Many thanks to the Carnegie Mellon Mach group for designing this superb operating system and for their openness and help. Thanks to Dave Rand and George Scolaro for designing the pc532 and making the design freely available. Thanks to Jukka Virtanen, Ian Dall, and Jukka Partanen for contributing time to this effort as well as to Bruce Culbertson and Bob Krause for the disassembler. The sources can be obtained through anonymous ftp from nic.funet.fi in directory pub/mach/pc532-src. The file pc532.MK78.tar.Z (245737 bytes) is a set of add-on files to the kernel version MK78 as distributed by CMU. Some binaries can be found in pub/mach/pc532-bin. New versions matching future CMU versions will be added when needed. Other useful sources and binaries, such as bnr2ss, libc, user programs, etc. will be added as soon as they work well enough and their uncontaminatedness has been verified. There is a mailing list mach-532@cs.hut.fi for persons interested in continued development of Mach for the pc532. To be added to the list or to be removed from it, please send mail to mach-532-request@cs.hut.fi. Johannes
