Development Environment IDE I believe that developing LX VII has met both goals I hope you will agree about its usefulness I know that it has served to introduce me to most aspects of code development using Cocoa s Foundation and AppKit frameworks Scope of This Manual This manual will describe the features of LX VII and will list the differences between its operation and how it differs from the original HP 67 It is not meant to be an introduction to the HP 67 s functionality If you want to learn about the HP 67 and more generally how to use RPN based calculators an excellent place to start is lt http www hpmuseum com gt An excellent tutorial to RPN can be found at lt http www hpmuseum org rpn htm gt The HP 67 information is found at lt http www hpmuseum org hp6797 htm gt Features of LXVII The major features of LXVII are listed in the Readme pdf file distributed with the program They are repeated here for convenience e A faithful representation of the HP 67 including its familiar keyboard layout e All buttons have keyboard equivalents via hot keys and are self documenting via tooltips All the programming features of the HP 67 are supported Program compatibility has been preserved as much as possible so the original HP 67 program libraries can be run with minimal or ideally no modification e LXVII is a document based application which means you can have multiple calculator instances ru
