Hi, I am installing a modchip (mayumi) of ps1 PU-20 ie a SCPH 7002, everything just fine that the track point 5 of mobo jumped, and I would need an alternative point on which solder. I kindly ask advice I attach scheme that I'm using
Right there on the ic chip I painted in red. i dont have that board handy though to be sure. Check with a multimeter.
ok, thank you, just that I neglected to say that he also tore the pin that you've marked in red. However, I scraped the surface of the chip and collected a pin filament and I connected the wire them. Not sure of the operation, since it does not recognize me the mod. pic. Thanks anyway. Tested original and working Cd. I do not know.
nothing even tried MM3, reads only backup copies, avoids both original and NTSC cd. I do not understand why used 2 of pic programmers always the same result. I remove the modchip and keep it for a future intallation of PSIO, it has seen serial port on the back. Thank you.
