This is a great opportunity to own a mint example of probably the best all round calculator ever made. It combines ease of use for day to day calculations with powerful programming features while avoiding the excessive complexity of later models. The calculator is mint, has never been used and has been stored since about 1990. The manuals are still in their original shrink wrapping and a case is included. The first time it will hold batteries is when I test it before sending so there is no terminal corrosion (batteries are not included). The box is slightly worn and scuffed as you would expect after long term storage but the contents are mint. Those of you with older HP41’s may want to buy this as a backup as they are not making any more !

The calculator uses Reverse Polish Notation (RPN) and has a full range of scientific functions as well as being programmable and made to Hewlett Packard’s high engineering standards. A wide range of accessories were developed for engineering, science, finance and even horse racing. These links to the Museum of HP Calculators will give you all the details and features:
