Introduction

In 1982, Hewlett Packard introduced what was. for me, the most amazing gadget I'd ever seen. To quote from page 10 of the Owner's Handbook:

The HP-16C Computer Scientist is a powerful problem solver, operating in either Integer mode or Floating-Point Decimal mode. In Integer mode you can perform integer binary arithmetic, number base conversion, bit manipulations, and logical operations. In Flosting-Point Decimal mode you can work out extensive floating-point calculations. Programming can be done in both modes. The HP-16C Continuous Memory retains data and program instructions indefinitely until you choose to reset it.

An important feature of the HP-16C is its extremely low power consumption. This efficiency eliminates the need for a recharger and provides a lightweight, compact design. Power consumption in the HP-16C is so low that the average battery life in normal use is 6 to 12 months. In addition, the low-power indicator gives you plenty of warning before the calculator stops functioning.

The HP-16C also conserves power by automatically shutting its display off if it a left inactive for a few minutes.

In 1989 HP discontinued production of the 16C. These web pages are dedicated to the memory of this fine tool. Here you will find:

This does not mean that Hewlett-Packard supports or in any way endorses this site. The simulation was not created by reverse-engineering the HP firmware. Their only connection with the software or these pages is one of inspiration. I have placed this notice here by way of acknowledgement of a job well done. Thank you HP.
