HP KEY NOTES was a newsletter that was sent out by Hewlett-Packard to owners of early model HP handheld programmable calculators. The newsletter was usually a combination of information from HP about new accessories, information regarding the HP-run User's Program Library, and tips about using the calculators. Initially, HP KEY NOTES was provided free for a while to HP-65 owners, then moved to a subscription basis about the same time as the HP-67 came out. HP KEY NOTES later covered the HP41C family and peripherals.

The articles re-published here are done so with the permission of the Hewlett- Packard company in the interest of preserving the history and technology behind these pioneering machines.
