Sharp EL-531VB Scientific Calculator

For anyone who needs to use the alternate functions of this or its sibling designs, the nearly illegible alt labels on this calc will be a continuing irritant. Sharp has come out with newer versions having black case and good contrasty keypad graphics that make the newer machines greatly superior tools even if they are otherwise identical. If you use a calculator as a tool rather than a fashion fob, do not put up with the sort of artsy idiocy Sharp and other makers tried to fob on the public with this machine and others (e.g. the equally idiotic TI-84 Silver from Texas Instruments and, incredibly, their very recent and otherwise superb TI-89 Titanium.)
