Any remote control that transmits Sony codes will work with a vintage IR capable Mac. However, you'll only be able to use the buttons on said remote control that are the same as those on the remote that you already have. So Power, TV/Mac, Channel up/down, Volume up/down, and Audio CD controls. I looked into this a few years ago to see if there's any way you can map remote control buttons to other functions, but IIRC their functions are hardcoded into the system.
