   Does anyone have the sources (I need the sources, not just binaries)

   BTW, I have the sources (and working binaries) for the VAX/VMS
 Modula-2 compiler if anybody wants it.  The VAX version was adapted
 from the PDP-11 version, and I?d like to find the original if I can. 
 Are you sure that Modula-2 came from the PDP-11?  I don?t remember it there.
 The VAX Pascal compiler was adapted from the ETH Pascal compiler for the
 CDC 6000 mainframes; the generated code from VAX Pascal V1 made this
 blatantly obvious.
