This electronic game console had to undergo a variety of variants including the gradual reduction in the number of external connectors on the unit. SCPH-900x series is the last revision to the original PlayStation with the same hardware
Early gamers used to experience skipping of full-motion video or dreaded physical "ticking" noises from the PlayStations. It was due to the poorly placed vents that caused overheating in the plastic moldings inside the console creating knock-on effects with the laser assembly.

Colored blue was another version of Sony Play station, followed by colored green. The PlayStation's capabilities were later expanded with the installation of a modchip, which allowed the playing of games from other regions.
Net Yaroze was introduced as another version of the PlayStation, which was much expensive. It was found to be lacking the features the full developer suite provided. The user found it difficult to officially make actual game discs as the amount of space was small. Sony launched the smallest version of its Play Station, PS one in 2000, which was about one-third smaller than the original PlayStation. Later it also released a small LCD screen and an adaptor that can be used in cars.
