Hello. I just got a new computer and I would like to use my old keyboard for it but my old keyboard isn't USB. And I only do soaftware so I don't really know what component or such I should use to make my non-USB keyboard be able to work with a USB. I dont know what my old keyboards plug is but its purple and not USB

Thanks for the help but I just bought a wireless logitech keyboard that I LOVE so I will probably just will be using this but thanks for the help!!!
