Here are the specs.  This clock features a computer connection port, an SD card slot for the photo viewer, and buttons, including a snooze button.  It also has an MP3 player, but no headphone jack.  How Strange.  It also does not have internal memory, which is why there in an SD card slot.  But, The real nice thing about it is the fact that it includes a color LCD display! Here are the specs.

Too bad the speaker and control wires are soldered  to the logic board.  The speaker is held on by two solder pads.  The button control cable connecter may look like it's detachable, but it wouldn't come out.  It looks like They get to spend the rest of their lives chained together.  But what about the LCD?  Is that replaceable? Too bad the speaker and control wires are soldered  to the logic board.  The speaker is held on by two solder pads.

they are 2 metal clamps held on by each one screw, holding the LCD down.  Make the screw a little loose and turn each clamp around.

Done!
  • Done!

  • I would give this a score of 7 out of 10. I am deducting 3 because some parts were soldered to the the logic board, making replacement difficult.

  • The good side is that the screen was replicable, and the fact that the whole thing was held together by screws, and not glue.
