A short news release announcing the impending June, 1967 introduction of the
Uchida Yoko USAC 10B electronic calculator.
The USAC 10B was the first electronic calculator made by Japanese conglomerate Uchida Yoko Co., Ltd., which had long been
in the distribution end of office equipment as one of their core businesses. The USAC 10B marked the company's entrance
into the fiercly-competitive electronic calculator market. As it turned out, the market proved to be far too
competitive for Uchida Yoko to be able to make sufficient money on their short-lived line of electronic
calculators, and they exited the electronic calculator manufacturing business just over two years later, in the spring of 1969.
The USAC 10B is a somewhat historical calculator as it was the first (as is currently known) electronic calculator
to have its logic implemented entirely with small-scale integrated circuits. The integrated circuits were made in America by
Fairchild Semiconductor, and were off-the-shelf members of Fairchild's µLogic family of Resistor-Transistor Logic (RTL)
small-scale bipolar integrated circuits. The calculators were marketed mostly in Japan and Europe, as Uchida Yoko did not
have a sales and marketing presence established in North America. Other known calculators in the short-lived line of calculators
produced by Uchida Yoko include the USAC 10R, USAC 22B, and USAC 22R.
