-----------------------------------------

We would like to announce the availability of MacMach - the CMU version
of Mach 3.0 for Macintoshes. Due to resource limitations, we are not able
to support this release to the extent that we do for other platforms. This
release is not being kept up-to-date with our source changes or new
Macintosh models. We can only make available what is currently working.

MacMach is the CMU Mach 3.0 microkernel (MK67) and the CMU Unix single-server
(UX28) with the Tahoe release of the BSD4.3 utilities.  X11R4 and GCC 2.3 are
included.  It does not include a working version of the Mac/OS emulator, so
it only supports a Unix style user interface. MacMach runs on the following 
Apple Macintosh computer systems:

  Macintosh II, Macintosh SE/30, Macintosh IIcx, Macintosh IIx,
  Macintosh IIci, Macintosh IIfx

MacMach kernels can be 32bit clean or 24bit compatibile.  MacMach requires
at least 8MB of ram and at least 80MB of disk.  Complete sources take up
250MB of disk.  A typical MacMach system is a MacIIci or MacIIfx with 16MB
of ram, ethernet and a 600MB disk.  MacMach can not use the internal video
of the MacIIci.

MacMach is available for immediate distribution to anyone holding a current
BSD4.3 Unix license, for "personal use only".  Apple Computer Inc. reserves
all commercial rights to MacMach.  Carnegie Mellon University is distributing
MacMach via the Internet free of charge.  Send e-mail to "MACH@CS.CMU.EDU" to
request license forms and installation instructions for MacMach. A brief
description of the installation instructions can be FTP'ed from mach.cs.cmu.edu
as the file FAQ/MacMach_install.doc as user anonymous.

MacMach is currently unsupported.  There is a mailing list for discussion fo
technical issues relating to MacMach, "MACMACH@CS.CMU.EDU".  Send add/delete
requests to "MACMACH-REQUEST@CS.CMU.EDU".

PLEASE NOTE:
The "Unix" part of MacMach is BSD4.3 and requires the appropriate $license$.
This effectively limits recipients to associates of corporations and/or
universities who have BSD licenses and the prerequisite AT&T/USL Unix source
license.  If you are an individual who can not be covered by such a license, 
you are out of luck.  CMU can not do binary-only distributions of Unix derived
code due to the conditions of our Educational Unix license.  The MacMach
license can be considered a site license.  Local administrators are allowed
to make multiple copies (under the contraints of your Unix license) after the 
initial download from CMU.
