Model #AT1. Just the cables (diagnostic port to interface and interface to serial port on laptop) and, of course, the interface itself. No software other than what Autotap has available from their website, which is easily downloaded (or I can burn to a CD). Am asking $150.00 shipped to your door. My wife has a bun in the oven...the baby is coming and some toys are going. Send an email to "scottandamy@mchsi.com" if interested.
