Known as version 1.1, the new TX Liteon DG-16D4S Unlocked Replacement PCB now has the unlock switch moved to the outside of the DVD drive so you can easily lock/unlock the write enable without having to take the drive apart.
We have also included LED's to indicate the boards WE status.
Due to it's huge success and ability to buy larger quantities of IC, we have also been able to lower the price by a massive $10 so the MSRP is now only $59.95.
Stock has already started to arrive at resellers so you don't have to wait to buy one
