"Toscal" BC-1411 calculator was made. It used an early form of Random Access Memory (RAM) built from separate circuit boards. Olivetti Programma 101 was made in 1965. It won various awards. Since it was a desktop electronic calculating machine that was programmable by non-specialists for individual use, it can be classified as the first personal computer. It added square roots to calculators. It weighed around 8kg but costed more than a family car. In 1967, Texas Instruments release a "Cal Tech" prototype. The "Cal Tech" could add, multiply, subtract, and divide, and print results to a paper tape while being compact enough to be held in the hand. This was the start of a new chapter in calculator history. In 1969, Japan released the Sharp's QT-8D Micro Compet. It used four Rockwell chips which equals about 900 transmitters. One chip was to power the green fluorescent display, the second chip was to control decimal point, the third chip was to handle digital addition and register input control and the fourth chip was to process arithmetic and provide registers. It is very primitive for todays' standards and replaced by the QT-8B which replaced the AC power supply circuitry with rechargeable cells, allowing it to be battery powered and completely portable. . Within a year 'handeld' calculators started to take off with machines like he Sharp EL-8, Canon Pocketronic and Sanyo ICC-0081 Mini Calculator. They sold well but were more than $2,000 in todays' money. The same year (1970), a Japanese company called Busicom released their Junior desktop model that boasted the first 'calculator on a chip' called the Mostek MK6010. The Mostek MK6010 combined all four functions plus decimal point and display on one 4.6mm-square chip. Soon many calculators of different types were invented. Each adding new things. For example, the HP-35 was an almost pocket-sized calculator with trigonometric and algebraic functions. They all led up to today's calculators. Calculators started becoming on phones and computers and tablets. There will probably be different thigns in store for the calculator.
