I have installed r-jtag into 3 consoles. 1 Jasper, and 2 falcons..... i prefer the jasper..... one falcon wouldnt boot R-Jtag no matter what i did, the other one worked great, but someone had previously reflowed it like twice, so after i put it together i gave it to my girls kid, and then it over heated.... so rrod there. But my jasper 256M with demon boots every time within 4 cycles usually takes 2 at most. and on my jasper i used jumpers 2-7-8, 1.8v jumper, and aud clapm wireing with 440Ohm resistor. Got perfecto boot times. every console is different though, so take your time, and do it right.
