NumberCrunch II version 2.1

license: without charge for individual and academic use

A "scientific calculator which emphasizes array and matrix operations." Requires "1 Meg of memory" and "system 6.07" (or later). The simpler NumberCrunch 1.45 is available from the same page. A slightly earlier version has long been my favorite program for simple calculations, for its simple text based interface - you type an equation and press return, and it's evaluated.
