Where might you plug that into a laptop? It doesn't say what type of connector it has. But it's not Firewire, USB or ethernet, unless you think that's going to replace one of memory modules, it probably isn't going to work. No one on any of the three Saab boards I've read over the last 4 years has been able to duplicate what the Tech-II does.
There is a similar proprietary tool used for Sea Doos called BUDS. And a guy over in Russia has claimed to have cloned it. No one on the Sea Doo board wants to risk the $1500 to find out if it works though... Ron
