the hardware is 2 cables and two box's. One box is the "chip" part that goes onto the computer. one of the cable's that is basicly a phone cable goes from the "chip" to a multi position knob. That multi knob is the 2nd box that you turn the knob to go to a diff. tune setting of the the settings is an off to turn off the tweecer and revert to the stock program. The second cable goes from the "chip" to the laptop.
Its a bit more than a single cable and not something that is easly pieced together unfortunalty...
However, the software is active after you properly install everything (there are a few things you must have to get it to work but they are avail. for download at the tweecer.com website). You can at least look at the tables, scalers, transfers and look at the starting guide to see what everyone is talking about.
I downloaded the software and played around with it before i got my tweecer when i was reading stuff about learning to use the tweecer. Made it a little easier to know how to navigate the software and stuff when i got it.
