The HP-35 was the first pocket calculator by Hewlett-Packard and the world’s first scientific pocket calculator; a calculator with trigonometric and exponential functions.
In 1970, HP co-founder Bill Hewlett challenged his colleagues to create a "shirt-pocket sized HP-9100". Slide rules where the only practical portable tools for performing trigonometric and exponential functions at the time as pocket calculators back then could only add, substract, multiply and divide.
The introductory price in 1972 was $395.
The “35” in the name of the calculator stems from the number of keys.
This original HP-35 was available until 1975.
In 2009, the HP-35 was called an IEEE milestone. The list of IEEE milestones describes the milestones of the "Institute of Electrical and Electronics Engineers", the most important historical achievements in electrotechnical and electronic engineering.
Complete with the original 110v/220v adapter and the original leather case. Also included is the original battery package consisting of three 1.2v aa cells, but these need to be replaced. The calculator can now only be used with the adapter.
Will be carefully packaged and shipped with track & trace.
