Trawling for info on "Eden" I was surprised to encounter a familiar name from my past life frequenting Foulab. It must be a small world for the handful of people interested in these chips.

Congratulations on the successful diagnosis and repair, and thanks for the writeup. I have a couple MSD3393 boards and--for a firmware reversing/hardware hacking novice like me, at least--this thread is an enormous help in figuring them out.
