Ran Fortran example on IBM 1401 emulator

A computer announced by IBM in 1959. Older than the 360. It was actually a very successful computer for it’s time. Lot’s of interesting stuff here.

Using simh, and this. It seemingly compiled/ran successfully, but results don’t match book. Perhaps a source problem. It’s late getting tired, more tomorrow.

It’s cool that it ran, however the output doesn’t match page 49 of this PDF. The source is furthur up in the PDF and it appears the same as what I ran.

Here is a real 1401, running the same program. Where I can also see the 1st PARAM card (not shown in the Fortran example PDF), matches my source.
