Software

FORTRAN, Assembler, RPG, disk and paper tape operating systems (DMS and PTS, respectively), and a few simple application programs were available for the 1130 when it was introduced. Over time the software library grew to include:

  • Disk Monitor System, Release 2 (DMS or DM2)
  • Paper Tape System (PTS), an OS for small systems with only paper tape I/O
  • FORTRAN
  • RPG
  • COBOL (which compiled its programs faster than a 360/50 and was popular for learning)
  • APL -- an interactive system that used the console keyboard and Selectric printer with a special APL font
  • Macro Assembler (which still has a few bugs... see the pages on building an simulator)
  • User programs, primarily shared through COMMON, a group of scientific users of IBM computing systems
  • Forth (in fact, Forth's first implementation was on the 1130, and its name is a result of DMS's five letter limit on filenames; otherwise we'd be using Fourth)
  • A full FORTRAN IV compiler (developed at Eastern Michigan University), an Algol compiler developed in France, and a BASIC interpreter, none of which we have much information about

The 1130 simulator, which you may download from the simulator page, includes has runtime kits for DMS/FORTRAN and for APL\1130. We have a large library of other IBM 1130 software on disk and punched card, cataloged in the library, which we plan to archive for your perusal and for use with the simulator.
