This Vintage IBM 1620 FORTRAN (with Format) Systems Reference Library dated 1963 is a rare gem for collectors of vintage computing and computing enthusiasts.  The library includes a manual for the FORTRAN programming language, as well as various reference materials for the IBM 1620 computer system.  File Number 1620-25, Form C26-5619-3.

It is in very nice condition considering age (no writing, no damage to any of its 97 pages).  See photos for examples that include black and white photos, flowcharts, and diagrams.  Pages are whiter than shown in photos.  Ships media U.S. Only.  No International.

S&H consists of packaging, invoice, time and travel plus actual cost when applicable.  Smoke-free.  See other IBM items listed.  I will answer all questions when possible.  Thank you for looking. Will combine shipping on multiple purchases. Just let me know before you pay so I can adjust invoice.
