|Sanyo CX-2103, inner workings|
This portable calculator resembles an old japanese cassette recorder.
Its size, its desk design, the chromed borders and the size confirm this.
From the technical side, this calculator is pretty interesting: The
mainboard consists of masses of discrete elements - lots of transistors,
arrays of resistors and electrolyt condensators. Additionally, there's
a single LED (as "Low Battery" indicator) and a flat panaplex display.
These display can be seen as predecessors of the green VFT displays.
In this panaplex display, the number "0" has burned in over the years.
This calculator is capable of the four standard calculation
methods (still with += and -= function), a memory function, a switch
for constant operations, 5/4 rounding and a fixed point function. There are
no floating-point operations possible.
Its difficult for me to fix a date for this calculator, since no
single electronics part inside carries an indicator for the
production year. So, I can only guess, and I estimate the year 1973.
