The world's first all-transistor car radio was manufactured by Philco in 1955, used the surface-barrier transistors in its radio's circuitry design.

And here was another one showing the coastline of Antarctica, and I couldn't identify this one but it certainly looked like circuitry designs.

"CMOS" refers to both a particular style of digital circuitry design, and the family of processes used to implement that circuitry on integrated circuits (chips).

Newer circuitry designs led to the PDP-8/I and PDP-8/L in 1968.

The world's first all-transistor car radio, was developed and produced by Chrysler and Philco in 1955, used the high-frequency surface-barrier transistors in its circuitry design.

Philco's high-frequency surface-barrier transistors was also used in the circuitry design of the first transistorized supercomputer.

Field theory, monopole field equations, circuitry design.

It used Philco's high-frequency surface-barriers transistors in its circuitry design.

This all-transistor car radio had also used Philco's surface-barrier transistors in its circuitry design.

This amp's circuitry design is commonly known as a 'single-ended, class A' amplifier.
