In January of 1954, supported by the military, engineers from Bell Labs built the first computer without vacuum tubes. Known as TRADIC (for TRAnsistorized DIgital Computer), the machine was a mere ...

The scientists Aylesworth talked to suggested there were probably additional impurities in the tin to make that first transistor work. So instead of the tin-doped germanium, Aylesworth used a ...

as well as the first microprocessor unit (MPU) ever demonstrated, beating the Intel 4004 by a year. In 1971, one of the designers of the F-14’s Central Air Data Computer (CADC) – [Ray Holt ...

This was the headline, 65 years ago, on a story in Electronics Weekly’s edition of September 7, 1960. The story opens: An all-transistor general purpose computer, the GE-225, has been developed by ...

about six years after Texas Instruments and Regency introduced the first transistor radio. Unlike traditional vacuum-tube televisions, which were bulky, fragile, and power-hungry, the TV8-301 was ...

the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the first silicon chips used bipolar transistors, most chips today use field-effect transistors wired as ...

This “transistor moment” was a game changer ... It was only a matter of time before we saw the first personal computer (1971) ...
