Info: The quest for small, light calculators began to focus on MOS (Metal Oxide Semiconductor) ICs, which had higher density and consumed less power than previous ICs.
But there was still no mass-production technology for MOS ICs and quality was still inconsistent.
Furthermore, MOS ICs were easily broken due to static electricity, and they were difficult to assemble.
Elaborate measures were taken to solve these problems: to prevent static electricity, humidity levels were raised in the factory, and line workers wore conductive wires on their wrists to ground themselves.
In 1968, after overcoming numerous hurdles, SHARP released the CS16A, a calculator employing MOS ICs.
Compared to the SHARP: CS10A, this product cost less than half (230.000 yen), weighed just one-sixth (4 kg), and was just one-third as large.
The CS16A sold well, and the company was one step closer to an electronic abacus calculator
