5 screw Nintendo Entertainment System (NES) cartridge back
 
5 screw NES cartridge top/front
 
In October of 1985, the Nintendo Entertainment System, abbreviated NES, was released. The original cartridge design used 5 screws to hold the plastic shell together (four corners and one in the middle). This design was later replaced by a 3 screw design that used plastic clips in the upper corners instead of the top 2 screws. The 5 screw design was phased out in 1988 and those cartridges are generally more sought after as collectibles because they represent something akin to a "first edition" to collectors, although some 3 screw cartridges may be rarer than the 5 screw variants. Additionally, there were a few third party manufacturers that appeared to randomly use 5 screw carts for repairs, which creates a lot of "possible" but not "probable" titles. This site is a place to gather some of the information about the 5 screw cartridges, a list of known cartridges, and links to other sites with additional specifics. It's also a place for general NES related information.
