ok.. let me try and clear things up..
you can get
THIS to wire directly to all 3 of your boards to read the nand like below
if you don't want to wire directly, you can install the QSB which is included in
THIS like below
if you're going to go the QSB route and you're buying the CR4 bundle, then you need to order 2 of
THIS as the CR4 bundle includes one set
yes, you're correct.. if you buy 2 extra sets of the QSB v3 (mainly for the nand QSBs) it comes with the jtag qsb for the falcon (non-xenon) consoles so you don'e have to buy
THIS
HEHE.. I hope you're gonna get a pro to install it for you seeing how just ordering the parts took up 2 pages
