You are bidding on a used MOTOROLA CABLE MODEM SURFBOARD SB4200. Themodem works great, but werecently switched to the Comcast Digital voice and received a new modem. I'm not a tech guy, so all I can tell you is it worked with Comast Digital Internet. Also, as of this writing there is no power cord included in the auction (they used it on the new modem), but I think it's a pretty standard one (flat on one side, round on the other). If I can find one, I will included it in the box, along with any other documentation I can find. Sorry about the out of focus picture.

I reserve the right to cancel bids from buyers who have "negative/NO or Private" feedback. Buyer pay actual shipping cost, I will combine shipping for multiple winning bids.
