Yesterday I bought an old fat PS2 pretty cheap, an SHCP 50004, and I got with it a free modchip. So far I've cleaned the PS2 out and found that someone tried to install this modchip, but apparently gave up, and now I'll try to install it myself, I have a fair share of experience with soldering things. However I can't seem to be able to determine what kind of modchip this is, it seems to be pretty decently made, but since I'm a newb at all this I wouldn't mind if someone could help me out.
It's not visible on the image below, because the camera doesn't focus very well, but the chip in the middle has UBICOM SX28AC/SS AB0317AE written on it. I tried looking for this, but didn't find much.
Also another question I'd have, is wether all modchips have the same wiring soldering sites, or is it dependent on the modchip itself?
Thanks for the help.
