Use your legacy PS/2 keyboards and mice with modern USB, equipped systems using this PS/2 Keyboard/Mouse to USB Converter Adapter.
This adapter cable allows you to connect a PS/2 keyboard and/or PS/2 mouse to any USB equipped PC. This can be particularly useful if you have a specialty keyboard or mouse device and a PC without PS/2 ports. It is also useful in a KVM (keyboard/video/mouse) extender situation, allowing PS/2 keyboards/mice to be used with USB KVMs.
No software or special drivers are required. Just plug it in and it works!
