I have for sale an NTSC Korean PS2, model SCPH-50005/N, the Network Adapter bundle edition. It comes equipped with a Matrix Infinity mod chip (1.93), an official Sony 8mb memory card, Sony composite and power cables, the official Sony Korean network adapter, and the horizontal stand.
The unit is 220V, as the previous owner kindly wrote in paint on the system but I believe PS2 power supply boards are modular and can be swapped. Still, I didn't want to do that and so I am selling this. It has been tested with all PS2 software (PS2-CD, PS2-DVD, PS2-DL DVD) and PS1 software from both NTSC-U/C and J. It runs quiet and well (disc tray also has good operation).
I can ship worldwide so message me for a quote with your location. I am asking $55 USD before shipping.
