I only know the address of "A+L AG", Switzerland. Perhaps it is helpful for
you. I have bought my Modula-II Compiler for the Amiga from there. But they
sell Compilers and Tools for many Computers, so perhaps they can help you.

The address is:

   A + L AG
   Daederiz 61
   CH-2540 Grenchen/SO
   Switzerland

so long...
