    i have soldered the 6 wires to the board but looking at this http://www.freewebs.com/jtagg/ theres a 3.3v power source (VCC) where does that power source come from?

    Hi If you have a mutimeter? the 3v3 comes from a diode to the right of the CPU just check for 3v3 its on the cathode end which is marked with a white band

    If you are using an active Jtag there should be a red wire on the lead. If it is a passive type(resistors only-non buffered) no Vcc is required.
