Uses
Edge connectors are commonly used in personal computers for connecting expansion cards and computer memory to the system bus. Example expansion peripheral technologies which use edge connectors include PCI, PCI Express, and AGP. Slot 1 and Slot A also used edge connectors; the processor being mounted on a card with an edge connector, instead of directly to the motherboard as before and since.
IBM PCs used edge connector sockets attached to ribbon cables to connect 5.25" floppy disk drives. 3.5" drives use a pin connector instead.
Video game cartridges typically take the form of a PCB with an edge connector: the socket is located within the console itself. The Nintendo Entertainment System was unusual in that it was designed to use a zero insertion force edge connector: instead of the user forcing the cartridge into the socket directly, the cartridge was first placed in a bay and then mechanically lowered into position.
