Someone can correct me if I'm wrong, but I don't think there is much difference between the older models and the newer ones. Yes, the older ones have a serial port so you needs a serial to USB cord, I think Zippers website has them on there. I had a pretty old model on my bike when I bought it which I have since switched out for the newer version because I found a good deal on one. A good bet would be to contact Zippers with questions, or Thundermax, they are pretty good at getting back to you with information. Hope that helps.
