Got an old xbox from a friend, which could not power on. I fixed it somehow so i can turn it on now. The problen is that the modchip was removed by my friend and he does not remember the wiring / connections : ( I've tried to search the web for the wiring diagram but couldn't find any. This modchip has almost same components as Duo X chips but the markings on the ICs are "NEO X"(xilinx IC) and "FUJITSU 512k" (another IC on the board) respectively. There is also a mark on the circuit board, "Neo X". The pins on the board are as followings:
GND
3.3V
L1
D0
A1
A2
A3
A4
A5
5V
The mainboard of the xbox is 1.6.
Does anyone see this modchip before? How do i connect this to the mainboard? By the way, according to my friend, the system was working fine before the power problem i.e can play backup, install evox etc.
Thanks and sorry for my bad English.
