Documentation on HP-65 Electronic Calculator

Hewlett-Packard Company encouraged owners of the HP-65 programmable calculator to write programs and share them with other users. These documents, donated by professional programmer Barry S. Berg, illustrate aspects of this process. Included are a contributor’s guide to the HP-65 user’s library, a sheet listing HP-65 application pacs [sic] from March of 1975, a set of HP-65 program forms from 1974, an HP-65 accessory order form from 1975, two issues of HP-65 Key Note for HP-65 Owners from 1976, and an issue of HP Key Notes from 1977. Several of the programs in 2012.3060.07 are listed in the 1977 issue of HP Key Notes.
An example of the HP-65 calculator (not used by Berg) is 2011.0023.01.
