ec4016.jpg (21672 bytes)The EC-4016 isn't a programmable calculator, but nevertheless it is a machine worthy of mention. Probably designed by Casio (all Radio Shack machines are OEM devices), it is one of the thinnest scientific calculators I've ever seen, and also one of the few solar power only scientific machines, and one that works quite well in low light conditions. But what's truly remarkable about this machine is its shape, size, and relative weightiness (it feels robustly heavy in your hand) which all lend it an aura of elegance. It is also a very well equipped scientific calculator indeed, containing not only the usual assortment of logarithmic, exponential, trigonometric, and hyperbolic functions, but also probability functions, fractions, single-variable statistics, numerous unit conversions, and several preprogrammed scientific constants.
