  Does anyone have the sources (I need the sources, not just binaries) for either the PDP-11 Pascal or Modula-2 compilers?  It’s probably on some DECUS tape somewhere, but I’m hoping someone can save me the trouble of searching.

  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.
