Canon immediately understood the Texas Instruments project started in September 1965 and ended in 1967 of Cal-Tech's potential. Together they developed the Canon Pocketronic, the first calculator based on LSI (Large Scale Scale Integrated) circuits. Three LSI circuits were needed to have a calculation capacity of 12 digits, 8 integers and 4 decimals.The calculator was manufactured in Japan but uses many components produced by Texas Instruments. In addition to the LSI circuits, they used the print head for thermal paper and transistors.
