PDP-11 Software Handbook

The PDP-11 Software Handbook provides an introduction to the software ecosystem for the PDP-11 family of computers. It covers a wide range of operating systems (RT-11, RSTS/E, RSX-11M, RSX-11S, IAS, DSM-11, and TRAX), language processors (such as MACRO-11, BASIC, COBOL, FORTRAN IV, APL, and FOCAL), and data management services (SORT-11, RMS-11, DBMS, and DATATRIEVE-11). The manual is intended to help system managers and programmers determine which software products are best suited to their specific processing environments and to provide foundational concepts for those using PDP-11 systems.
