Since November 2, 1975 I have kept in my possession a 14 13/16” x 11” x 1 7/16” listing of the 3.4 release of the Pascal compiler for the CDC 6000 series computers. This listing includes the compiler (128 pages), cross reference (36 pages), and Pascal library source, some of which is written in Pascal and the rest in COMPASS, the CDC assembly language (144 pages).

The listing begins:

Yet I think I have been outdone. Several listings of the Pascal compiler have been scanned in and made available as PDF files here. Perhaps, some day, a software archeologist will want to know the differences between the 1/8/75 Release 1 compiler and the March 1976 Release 2 compiler [PDF file].
