IC-based Electronic Calculators Under Development at Hayakawa Electric (Sharp)
Electronics Magazine, January, 23, 1967
A brief article stating that
Hayakawa Electric (Sharp) is working on the development of integrated
circuit-based electronic calculators using bipolar IC's from
Mitsubishi (which first ended up being used in the
Sharp Compet 31 (CS-31A),
which came to market in February of 1967, just shortly after this article
was published.
Also mentioned was the use of
Metal-Oxide Semiconductor (MOS) integrated circuits
manufactured by Nippon Electric Co. (NEC). which first appeared in
the Sharp Compet 16 introduced
in December, 1967.
Sharp was not the first to use Integrated Circuits in
an electronic calculator (that distinction goes to Victor Comptometer in
the US, with the large-scale MOS IC chip set made by General Micro-electronics
providing the logic for the
Victor 3900), but Sharp
was an early pioneer in the use of Japanese-made integrated circuits
in their electronic calculators, and once bitten by the IC bug, jumped
headlong into the development of calculators that used increasingly
fewer discrete electronic components.
