The IBM 1401 compiles and runs FORTRAN II

From CuriousMarc: “We attempt to compile and run a simple FORTRAN program on our vintage 1959 IBM mainframe computer at the Computer History Museum. FORTRAN is a big stretch for this business oriented machine, with 16k memory and a CPU not meant at all for scientific applications. Even integer multiply and divide instructions are an optional feature on the base machine! Success not guaranteed.”
