Description from the seller

The HP-27 was a portable scientific and financial calculator, but non-programmable, produced by Hewlett-Packard between 1976 and 1978.

Unlike all of HP's previous pocket calculators, the HP-27 could perform mathematical, statistical, and business calculations.
It used Reverse Polish Notation (RPN) for calculations, with a four-level stack system (x, y, z, t).
Almost all keys had two alternate functions, selected with a yellow and a black key.
Despite the keyboard having only 30 keys, it could thus access about 68 functions.
The HP-27 also had a red LED display with 10 digits and 10 registers to store numbers.

Shipped in good used and working condition, complete with adapter, manual and packaging materials.
