Electronic Hand Held Calculators
Rockwell Calculators- While HP and TI were battling it out, across the Atlantic UNICOM in the United Kingdom was working on pocket handheld calculators. In 1973 Rockwell International (an Aerospace Company who built the Apollo) bought UNICOM and decided to get into the calculator business. The calculator design and marketing was moved to Anaheim, CA called Autonetics where microchips were designed.. Unlike HP or TI, Rockwell assembled their calculators in Mexico, Japan and the UK. Shown below are examples of Rockwell's first generation calculators. They called their calculators "The Answers". Rockwell would leave the business by 1977-1978 as they saw the market shrink and they would not be able to compete.
Unlike the basic Rockwell Calculators, such as the 10R, 20R and 30R, the following models used larger and easier to read fluorescent displays, larger key pads and rechargeable batteries.
