Calculators
- Pocket calculator
- The first portable calculators appeared in Japan in 1970, and were soon marketed around the world. These included the Sanyo ICC-0081 "Mini Calculator", the Canon Pocketronic, and the Sharp QT-8B "micro Compet". Sharp put in great efforts in size and power reduction and introduced in January 1971 the Sharp EL-8, also marketed as the Facit 1111, which was close to being a pocket calculator. It weighed about one pound, had a vacuum fluorescent display, and rechargeable NiCad batteries. The first truly pocket-sized electronic calculator was the Busicom LE-120A "HANDY", which was marketed early in 1971.
