A Casio FX-602p programmable calculator The Casio FX-602p is one of the most sought after calculators in the world and is widely regarded as ranking amongst the best calculators ever made. A real testament to the quality and power that Casio products are known for. In good shape, has some signs of use on the case and calculator (see pictures). The lower part of the back is a bit loose, this seems to be a common problem with this type of calculator, and will not influence the way it works or looks. Has been tested, works just fine. Comes with batteries included. Does not include the manual that came with the calculator, the manual can however be found online. This is the best and most usable programmable calculator ever. The user interface is very good and clear, the display is fantastic and its interfacing options are adequate. The Casio fx-602 has 512 programming steps, more than enough for most tasks. A rather funny 'function' of this calculator is its ability to play music using its cassette interface. A special keyboard overlay for this function was also available and part of the standard package. The manual even listed a couple of songs that could be played in this manner! A real collector's item. Will be shipped in protective packaging
