I was recently given an old PS2 slim. It seems to be a rare 'Test' Debugging Station, model DTL-H75000A. There was no box, manuals or discs with it.
It can play old PS One games and audio CD's, but when I put in a DVD is displays the message "DVD Player is not set up"
Looking at the firmware revisions from the front screen, there is no version for a DVD player.
Any ideas how I can get it to play DVD's ?
