From the The Hewlett Packard Calculator Page.

This poster shows every HP calculator made starting with the famous HP-35. Each calculator is displayed with it's production start and end data, and it's project codename.
It's amazing how many of these I have actually used. This is similar to the Evolution of Apple Design...but with more buttons.
