cartridges that could be swapped out and that contained their own processor as the console itself had no on-board processor. It had a small game library which was prone to damage from static electricity and the LCD screen could also rot. These two factors contributed to its discontinuation two years after release. Entex Select-A-Game & Adventure Vision Entex released two handheld systems in the second generation, the Select-A-Game and the Adventure Vision. There were 6 games available for the Select-A-Game but it was only available for a year until focus shifted to the Adventure Vision which was released in the following year. The Adventure Vision was released only in North America in 1982 by Entex and was the successor to the Select-A-Game. It was unique among the consoles as it used a spinning mirror system for its built-in display and had to be used set down on a surface due to its size and shape. It was discontinued one year later in 1983 after selling just over fifty thousand units. Palmtex Super Micro Developed and manufactured by Palmtex, the Super Micro was released in 1984 and discontinued later that year. Due to financial problems between Palmtex and Home Computer Software, only three games were released for the system despite more being planned. It was criticized for its poor build quality and how easily it would break, and sold fewer than 37,000 units. Epoch Game Pocket Computer The Epoch Game Pocket Computer was released in Japan in 1984. Due to poor sales, only five games were made for it and was not released outside of Japan. Nintendo Game & Watch The Game & Watch was a series of 60 handheld consoles that contained a single game in each release. The first, titled "Ball" was released in 1980 and titles were released up until it was discontinued in 1991. Unlike the other handheld consoles in the second generation, the Game & Watch had a segmented LCD screen similar to a digital watch which limited the display to the configuration of the segments. The series sold a combined 43.4 million units, making it the most popular handheld of the generation.
