a 10+2 c-power scientific model with rubber keys
from 1987. i like this machine. it has quite a good set of features, easy to
use, algebraic entry rather than formula and its even programmable.
it has a lot in common with the fx-992v. in
fact i think it can do everything on the 992v and more. additional
features include, 29 step blind programs, 23 built in formulae and
physical constants. despite being programmable, there is no numerical
integration, unlike the fx-3800pv
there are 23 built in scientific formula. they operate in the same
manner as the fx-5000f, which has 128 of them.
when recalled, the formula prompt for data values, then execute a preset
calculation. the sort of things stored are simple text book formula for
triangles, areas, quadratic equations and so on. ie nothing complicated
that involves iteration or loops. nevertheless, this feature is still a
bonus if you can remember the code numbers.
the c-power is a solar panel and also a gr927 battery. i dont
know if the panel can charge the battery, but it is possible for the
battery to be run down and replacement involves taking the machine apart.
the solar panel is a bit small, but it can still power the machine under
artificial light.
an easy to use arrangement for number bases here, especially if you use
dec and hex a lot. all the operations and the A-F keys
are on keyboard once in base mode and you can switch between bases easily.
