Grundy NewBrain and Bally Astrocade, are types of electronics?
yes
Bally Astrocade
The Astrocade is a second generation home video game console and simple computer system designed by a team at Midway, at that time the videogame division of Bally.
 It was marketed only for a limited time before Bally decided to exit the market.
 The rights were later picked up by a third-party company, who re-released it and sold it until around 1984.
 The Astrocade is particularly notable for its very powerful graphics capabilities for the time of release, and for the difficulty in accessing those capabilities.
Grundy NewBrain
The Grundy NewBrain was a microcomputer sold in the early 1980s by Grundy Business Systems Ltd of Teddington and Cambridge, England.
Professor Pac-Man
Professor Pac-Man is a quiz arcade game that was produced by Bally Midway and is the seventh title in the "Pac-Man" series of games, which was released in August 1983.
 Like "Ms. Pac-Man", "Pac-Man Plus", "Baby Pac-Man" and "Jr.
 Pac-Man", it was created without authorization of Namco, who are the original creators of the "Pac-Man" series.
 It is also the last of only seven games from Bally Midway Manufacturing to run on their Midway Astrocade hardware. Blue Print (video game)

 The player controls J.J., a man whose girlfriend Daisy is being chased by Ollie Ogre.
 To defeat him, J.J. must find the pieces of a machine based on a blueprint.
 Home ports of "Blue Print" were published by CBS Electronics for the Atari 2600, Atari 5200, and Commodore 64. Astro Battle 2009
Astro Battle 2009 (or sometimes just Astro Battle) is a Space Invaders clone published by Bally Manufacturing in 1978 for the Bally Astrocade arcade system.

Gun Fight, known as Western Gun in Japan and Europe, is a 1975 arcade shooter game designed by Tomohiro Nishikado, and released by Taito in Japan and Europe and by Midway in North America.
 It was the first video game to depict human-to-human combat, while the Midway version was also the first video game to use a microprocessor.
 Following its November 1975 release in North America, it went on to sell over 8,000 arcade cabinets in the United States.
 It was ported to the Bally Astrocade video game console as a built-in game in 1977 as well as several home computer platforms. Wizard of Wor
Wizard of Wor is an arcade game released in 1980 by Midway.
 Up to two players fight together in a series of monster-infested mazes, clearing each maze by shooting the creatures.
 The game was ported to the Atari 8-bit family, Commodore 64, Atari 2600, and Atari 5200 and renamed to "The Incredible Wizard" for the Bally Astrocade. List of pen types, brands and companies
This is a list of pen types, brands and companies.
 A pen is a handheld device used to apply ink to a surface, usually paper, for writing or drawing.
 Additional types of specialized pens are used in specific types of applications and environments such as in artwork, electronics, digital scanning and spaceflight and computing. Modular crate electronics
Modular crate electronics are a general type of electronics and support infrastructure commonly used for trigger electronics and data acquisition in particle detectors.
 These types of electronics are common in such detectors because all the electronic pathways are made by discrete physical cables connecting together logic blocks on the fronts of modules.
 This allows circuits to be designed, built, tested, and deployed very quickly (in days or weeks) as an experiment is being put together.
 Then the modules can all be removed and used again when the experiment is done. Marine electronics
Marine electronics refers to electronics devices designed and classed for use in the marine environment on board ships and yachts where even small drops of salt water will destroy electronics devices.
 Therefore, the majority of these types of devices are either water resistant or waterproof.
