Hey you guys, we are in the........ damn, that's John's line.
Whatever, i need your help with something. I just bought an el-cheapo Ms Pacman bootleg board. I knew it was defective, the guy who sold it said that the board was booting, showed some pacmans on the screen and then reboots. Having watched almost all the vids on the one circuit channel (thanks Adam!!) this might lead to the conclusion there is something wrong with circuit which is driving the watchdog.
So far so good. I do repairs on MPU boards from pinball machines and i want to dive into arcade PCB repairs, that's the main reason i bought this bootleg board.
After searching the internet for schematics of this board i came up empty. Is there someone who by chance has got this schematic???
This is the board (a simular one)
