Collecting calculators you'll sooner or later recognize Japanese Sharp Corporation company. In the race started with the Cal-Tech project in the year 1965 and leading to the Canon Pocketronic calculator in the year 1970 they won some medals:
• 1969 Sharp introduced with the
QT-8D the first calculator
using LSI-IC's (Large-Scale-Integration Chips) manufactured by US company Rockwell Electronics
• 1970 Sharp introduced its first battery operated desktop
calculator QT-8B
• 1970 First battery operated, handheld calculators: Busicom LE-120,
Canon Pocketronic,
Sanyo ICC-82D and
Sharp EL-8.
The Sharp Corporation was founded in 1912 by Tokuji Hayakawa and takes its name from one of our founder's first inventions, the Ever Sharp propelling pencil, developed in 1915. Sharp introduced the world's first all-transistor desktop calculator in 1964. In the next 20 years they developed a lot of "firsts" in the calculator business, mainly together with its pioneering research into Liquid Crystal Display (LCD) technology.
