Relive a classic of 1970s computing. This app faithfully emulates the HP97, Hewlett-Packard's desktop programmable calculator. The HP-97 packed in many features we now associate with computers: a built-in printer, magnetic card storage, and memory for both data and programs. Programming is simple. In program mode, you enter the same key sequence you'd use to do a calculation by hand, then replay it whenever you need to repeat the work. Built-in statistical and mathematical functions, including square roots, logarithms, and trigonometry, make it a capable tool for serious calculation.
