scientific version of the anita
810 made by sumlock comptometers ltd uxbridge england, manufactured by
rockwell in 1974.
this machine operates like a normal scientific calculator, gone is the
weird desk calculator input style of the 810 and of regular desktops like
the anita 811sl and gone is the strange fix 2
rounding mode. instead the switch now defined as a radian/degree mode
selector.
a pleasure to use and hold this machine has a cool 70's retro style,
sprung buttons and a brushed aluminium metal slide open back revealing the
battery compartment which takes 3 'AA batteries.
a good set of scientific functions are on offer, natural and common
logs, trigs and their inverses, square root, reciprocal, pi and x^y. a
rather interesting set of memory and x<>y swap and move functions
are also present which combine in powerful ways to accelerate
functionality. these tricks are explained in the manual.
