Two PS/2 ports: one colour-coded, the other colour neutral
Named for the old IBM PS/2, these connectors have been widely used as the standard interfaces for keyboards and mice, but are slowly giving way to USB. The following colour coding schemes for connectors are widely used:
It's also quite common to see such connectors in a neutral grey colour on both mouse and keyboard. Switching the mouse and keyboard connections on the motherboard port block is possible, but is harmless. If you do this you will quickly know it, because if these connections are switched neither mouse nor keyboard will work. Many PCs won't even boot if keyboard and mouse are inadvertently switched. The fix is quick and easy: switch the two connectors around the right way, and everything should work!
