The sales box of the AccuBalance Personal  Digital Account Register sold around 2010 in the US.

This AccuBalance Personal  Digital Account Register was manufactured in November 2010 in China.

The internal construction of the AccuBalance makes use of just 2 printed circuit boards (PCB's),
one for the gray-scale LC-Display and another one for the computing unit and power supply. 

The brain of the AccuBalance is actually a System-on-Chip based on the ARM7TDMI-S 16/32-bit RISC processor.
