The HP 15C was a very popular RPN calculator from the 1980s (1982-1989) that, despite the last units rolling off the line over 30 years ago, is still highly sought after by collectors and users. After a long wait, the HP 15C is now being temporarily re-released as a Collectors Edition.

This special Collectors Edition comes in a nice storage box, including a printed manual like the one from 1984 with a foreword on the history of HP's calculators, written by Włodek Mier-Jędrzejowicz and Gene Wright.

Enhanced version of the classic HP 15c

After a 12-year hiatus, HP is reintroducing the popular HP 15c Scientific Calculator. This HP classic features a unique “Collector’s Edition” script, making it a great gift for collectors and engineers alike. The 15c offers users a high-end and portable, scientific calculator with programmable functions and built-in support for complex numbers, matrix math, numerical integration, and root solving, which makes this device one of the most capable calculators HP has ever made.

Intelligent design, powerful processing

The Collector’s Edition HP 15c maintains the same intelligent design as the original but touts up to 100x faster processing speed. Its compact size and lightweight metal frame allows users to conveniently carry the HP 15c from meeting to meeting. Unlike other scientific calculators, the HP 15c also offers an intuitive, horizontal interface, just like the original.

Rich set of advanced scientific features with more memory

The HP 15c is a powerful problem solver. Programming capabilities include conditional and unconditional branching, subroutines, flags, and editing. Plus, users can program up to 672 steps of calculations for rapid retrieval (increased from 448). The new 15c also offers Direct and indirect storage in up to 99 registers (increased from 67). This handy calculator operates using Reverse Polish Notation (RPN), reducing the number of keystrokes to complete your calculations.

There is 5% discount for 5 units or more, 10% discount for 10 units or more.

The overlay is NOT a HP product. It is used with non-manufacturer-supported features of the HP15c CE calculator. HP and its licensees are not responsible for its use and suitability for any application, and will not give support on its use - go instead to user webs like hpmuseum.org. The overlay is intended just for exploration of the calculator features, and it is designed and produced by The Calculator Store SLNE. There are known bugs in the HP16c mode.

IMPORTANT NOTE: The production units do not have protective plastic on the calculator surfaces, as shown in the video. This was only done on the 5 test units sent to us
