I have my computer open that has an AMDK6-2 CPU in it. How can I determine which motherboard I have? From this info, I want to determine if I can attach a new USB keyboard and mouse to the system. It doesn't have an obvious USB connector on it, but people at work told me that there might be pins onto which a USB female port can be put on. Failing that, is there such as thing as a USB card I can purchase?
