The HP 35s (F2215A) is a Hewlett-Packard non-graphing programmable scientific calculator. Although it is a successor to the HP 33s, it was introduced to commemorate the 35th anniversary of the HP-35, Hewlett-Packard's first pocket calculator (and the world's first pocket scientific calculator). It somewhat resembles the original HP 35, but it is larger, with 43 keys and a two-line L.C.D. instead of red light-emitting diodes. 

The HP 35s has been given a retro look reminiscent of classic HP calculators from the 1970s to the 1990s. However, it provides far more functions, processing power, and memory than most of those earlier models. This brand new, unopened package includes calculator, manual & protective case. This will be shipped USPS Priority Mail, Tracked & Insured. 

Features:

The HP 35s uses either Reverse Polish Notation (RPN) or algebraic infix notation as input.

Two-line alphanumeric LCD

Over 800 memory registers (26 directly labelled)

Scientific and statistical functions

Operation in decimal, binary, octal, hexadecimal

Equation solver with arbitrary variable isolation (first seen on the HP-18C)

Numerical integration (first seen on the HP-34C)

Support for input and display of fractions

Complex number and vector calculations

Unit conversions and table of physical constants

Keystroke programmability with approximately 30 kilobytes of memory for programs and data
