It’s hardly surprising that semiconductor companies were reluctant to invest much energy into MOSFET development in the early 1960s. Early MOSFETs were 100 times slower than bipolar transistors, and they were considered unstable, for good reason: their electrical characteristics drifted badly and unpredictably with time and temperature. A lot of research and development work would…
Ray Holt was a most unlikely candidate to develop a microprocessor chip set for the US Navy’s new F-14 variable-wing fighter jet. From an early age, Holt was a lackluster student, fully committed to a planned career as a professional baseball player. In 1962, as a senior at Dominguez High School in Compton, California, career…
We love firsts in this industry, despite the fact that “the first” anything doesn’t necessarily win the market. Sometimes the first to market does win. Sometimes it doesn’t. When it comes to microprocessors, there’s an ongoing battle to claim bragging rights on being the first. Usually, the argument revolves around three contenders: …
Ken Shirriff's blog Reverse-engineering an early calculator chip with four-phase logic In 1969, high-density MOS integrated circuits were still new and logic circuits were constructed in a variety of ways. One technique was "four-phase logic", which provided ten times the speed and density of standard logic gates while using 1/10 the power.1 One notable application of four-phase logic was calculators. In 1969, Sharp introduced the first calculator built from high-density MOS chips, the QT-8D, followed by the world's smallest calculator, the handheld EL-8. These calculators were high-end prod...
