Radio-quiet neutron star Radio-quiet neutron star A radio-quiet neutron star is a neutron star that does not seem to emit radio emissions, but is still visible to Earth through electromagnetic radiation at other parts of the spectrum, particularly x-rays and gamma rays. Most detected neutron stars are pulsars, and emit radio-frequency electromagnetic radiation. About 700 radio pulsars are listed in the Princeton catalog, and all but one emit radio waves at the 400 MHz and 1400 MHz frequencies. That exception is Geminga, which is radio quiet at frequencies above 100 MHz, but is a strong emitter of X-rays and gamma rays. In all,
Racing the Beam speed electron beam across the screen. "Racing the Beam" discusses the history of the VCS platform and the design decisions that impacted the types of games that could be written for it. Specific titles such as "Combat", "Pitfall!" and "Yars' Revenge" are analyzed from a technical and cultural perspective. "Racing the Beam" is the first in a series of books on early video game platforms, and has been cited by modern Atari 2600 enthusiasts as an inspiration for attempting to write new games for the platform.
