  1. With the advent of MOS/LSI in 1970, early portable calculators using more than one major IC and priced at around $300 to $500 were produced using LSI circuits. TI's single MOS/LSI calculator-on-a-chip IC in 1971 heralded the age of the low-cost consumer handheld calculator and ignited the burgeoning electronic calculator market
  2. Handheld calculators were introduced into the United States in 1970 and 1971 by the Japanese firms of Busicom (Nippon Calculating Machine Corporation) and Sharp (Hayakawa Electric) as well as the American firm of Bowmar. Chips in early Busicom calculators were made in the United States by Mostek, while those in the Bowmar and Canon were by Texas Instruments. Hewlett-Packard Corporation joined the market in early 1972 with the HP-35 scientific calculator. It could not only add, subtract.
  3. Curtas were considered the best portable calculators available until they were displaced by electronic calculators in the 1970s. Herzstark continued to make money from his invention until that time, although, like many inventors before him, he was not among those who profited the most from his invention
  4. The Curta calculator, which first appeared in 1948, was perhaps the ultimate expression of the mechanical calculator, so compact that it could, somewhat lumpily, fit into a pocket and was capable of addition, subtraction, multiplication and division
  5. The calculator cost $795 when it launched in 1974. In 1975, during the first joint U.S.-Soviet space flight, it became the first handheld calculator in outer space. Interesting Fact: Bill Hewlett specified in the design requirements that the calculator had to fit in his shirt pocket — one reason for the machine's tapered shape
  6. (Victor did briefly sell some pocket and portable calculators during the early 1970's, but apparently most were made for them by other companies.) 1964-67 -- The first large electronic desk-top calculators begin to replace electro-mechanical machines. Those models, based on the newest electronic technology, use thousands of transistors, cost thousands of dollars, and weighed 30-60 pounds. Sharp's Compet CS-10A and Canon's Canola 130 are two early electronic calculators among the offerings.
  7. FIG. 1 is a perspective view of a portable handheld calculator embodying the present invention wherein the slidable solar panel is exposed to the light; FIG. 2 is a simplified cross-sectional view..

Some 150,000 Curta calculators were made between 1948 and 1970, production ending with the advent of the electronic calculator. No truly mechanical calculators have been invented since. The Curta. Later a battery pack was added to create the Model QT-8B, one of the first portable calculators. According to datamath.org, the original price was $495. (I have seen an old ad stating a $395 price, however.) $495 in 1969 dollars equals an astonishing $2,868.96 in 2009 dollars. The QT-8D was nevertheless not only much smaller than prior electronic calculators, but also much less expensive. It has a green fluorescen
