This vintage IBM operating system (1410-PR-155) was used for the 1410/7010 model and dates back to 1965.  The manual is in good condition and has been well-preserved over the years.  It is a great collector's item for those interested in vintage computing. The manual is written in English and is easy to understand.File No. 1410/7010-30, FormC28-0322-3.

It is in nice condition considering age (no writing, no damage to any of its 64 pages except for a few browned edges from aging).  See photos for examples that include black and white photos, flowcharts, and diagrams.  Pages are whiter than shown in some photos.  Ships media U.S. Only.  No International.
