A couple additional notes:

- I opened the unit and found that there is no hard drive. I must have pulled the hard drive to revive my other Empeg long ago.
- After plugging in a 12V power supply, I saw that the screen works and everything appears intact but I get a "Player Settings Lost" message and of course a notification of no hard drive.

It looks like this stuff is suitable for spare parts or perhaps reconstituting a new Empeg/RioCar if you supply the drive.
