An early 2000s transistor radio (Sony Walkman SRF-S84 transistor radio, released 2001, shown without earphones) Rock 'n roll music became popular at the same time as transistor radios. Parents found that purchasing a small transistor radio was a way for children to listen to their music without using the family tube radio.
In the 1960s, company best seller products became transistor radio receivers. One of the most famous was the Koliber model. In 1969, three- band receiver models were available ( Dominika and Izabella ), as previous radios could only receive two bands, low frequency and medium wave , and a year later the Laura 4-band receiver came into production.
Chrysler and Philco announced an all-transistor car radio in the April 28, 1955, edition of the Wall Street Journal. [1] This Philco car radio model was the first tubeless auto set in history to be developed and produced. [2] It was a $150 option for 1956 Chrysler and Imperial cars and hit the showroom floor on October 21, 1955. [3] [4] [5]
The all-transistor car radio was a $150 option. [51] [52] [53] The Sony TR-63, released in 1957, was the first mass-produced transistor radio, leading to the mass-market penetration of transistor radios. [54] The TR-63 went on to sell seven million units worldwide by the mid-1960s. [55]
Zenith Royal 1000 All Transistor Trans-Oceanic Short Wave Portable Radio, circa 1957. Soon after the introduction of the 1000 model, a second model, the Royal 1000D, added the LW band covering 150 kHz through 405 kHz just below the AM broadcast band. There were also slight cosmetic differences to distinguish the two models.
1955 Chrysler - Philco all transistor car radio - "Breaking News" radio broadcast announcement. (Optional on 1956 Imperial car models) On April 28, 1955, Chrysler and Philco announced the development and production of the world's first all-transistor car radio, [17] the Mopar model 914HR. It was developed and produced by Chrysler and Philco and ...
TRADIC. This is a list of transistorized computers, which were digital computers that used discrete transistors as their primary logic elements. Discrete transistors were a feature of logic design for computers from about 1960, when reliable transistors became economically available, until monolithic integrated circuits displaced them in the 1970s.
The fourth generation (VLSI) was also largely out of reach, too, due to most of the design work being inside the integrated circuit package (though this barrier, too, was later removed [24]). So, second and third generation computer design (transistors and MSI) were perhaps the best suited to being undertaken by schools and hobbyists. [25]
