Sharp Microelectronics Intergrated Circuit Chip Tie clasp (1970s)
​​

Sharp Electronics Semiconductor IC
Item #953
This tie clasp from Sharp Microelectronics features one of their  Integrated Circuit Chips. The only identifier on the chip is "10004".

Sharp started selling transistorized calculators in 1964. In 1967, Sharp would introduce their first IC-based Electronic destop calculator that used MOS Integrated Circuits made by Mitsubishi.

​In 1971 Sharp would introduce the worlds first battery powered handheld electronic calculator, 
the Sharp QT-8B "micro Compet", which used 4 MOS LSI IC's made by Rockwell.

Sharp had numerous competitors in the growing electronic calculator market including american calculator maker Smith-Corona Marchant, and japanese calculator makers Sony, Casio, Canon, Hitachi, Busicom, and Oki Electric Co. 

Each of these early Japanese calculator companies would come out with their own unique calculator designs with Integrated Circuits supplied through individual alliances with key American semiconductor companies. Many of whom would go on to make their own line of calculators, including
 General Instrument,  Texas Instruments, and Hewlett Packard.


​North American Rockwell Microelectronics was the key manufacturer of LSI calculator integrated circuits for Sharp's calculators. The list of Integrated Circuit manufacturers who became suppliers to the early electronic calculator industry included Intel, Texas Instruments, North-American Rockwell Microelectronics, Mostek, Motorola, AMI, Fairchild Semiconductor, RCA, National Semiconductor, Mitsubishi, and Sanyo.
