Modula-2 and the origins of our family of Modula-2 compilers have been designed and developed at the Department of Computer Science, ETH Zürich in Switzerland (see http://www.inf.ethz.ch) by Niklaus Wirth and his team.
In December 1981, we licensed the sources of the M2M compiler (4-pass compiler for the famous Lilith architecture) and derived new compilers from it for the Concurrent 3200 architecture, the m68k processor and the SPARCv8 architecture. All these compilers conform to PIM3 (Niklaus Wirth, Programming in Modula-2, 3rd Edition, Springer-Verlag) but not to the ISO/IEC standard 10514-1:1996.
Modula-2 and the origins of our family of Modula-2 compilers have been designed and developed at the Department of Computer Science, ETH Zürich in Switzerland (see http://www.inf.ethz.ch) by Niklaus Wirth and his team.
This compiler was initially cross-developed for a Nixdorf Targon/31 (based on the m68k architecture) and later ported the m68k-based Sun 3 architecture running SunOS 4. These sources are the latest release we developed for the Sun 3 running SunOS 4.1.x.
We have an agreement with the ETH Zürich that the sources which have been derived from the M2M-compiler may be freely redistributed provided that
all derived sources clearly state that Modula-2 has been designed and developed at the Department of Computer Science, ETH Zurich in Switzerland.
All sources of the compiler of this distribution may be freely redistributed if you follow the above term for the ETH-derived sources and the terms of the GNU General Public License, Version 2 (as found in the file COPYING).
The sources in the directories m2b, m2c, m2e, mdb, mmm, and mprof may be freely redistributed under the terms of the GNU General Public License, Version 2 (as found in the file COPYING).
The sources of the library (subdirectories lib and rts) may be freely redistributed under the terms of the GNU Library General Public License, Version 2 (as found in the file COPYING.LIB).
Note that the MathLib module has been derived from the GNU library (distributed under the terms of the GNU Library General Public License) which in turn has been derived from sources which have been developed at the University of California, Berkeley: This product includes software developed by the University of California, Berkeley and its contributors.
Binaries are available for SunOS 4: https://www.mathematik.uni-ulm.de/modula/downloads/sun3/
