I have created this page for all users who want to create a port for the Sony Walkman NWZ-A728 media player. Or a similar player. I encourage other users to post any information they have on the players, and I will try and find as much information on the hardware as I can. I would like to get PCB scans, but I only have one player, and it is in good working order and brand new so I do not want to go ripping it apart.

Pictures of the player(including a picture of it playing video):

Some of this information(weight, etc) are not as important, but I do believe screen dimensions are. I welcome users to add information about the hard ware, as well as PCB scans, so we can work on getting a working port. I will continue to search for more detailed specs, and post information as it becomes available.
