TL;DR: There is little hope of keeping the original control panel and having it interface with any modern control board. There are way too many weird electronics to even bother making an interposer board for. Read the chip info in my reddit post. I'm sticking with running the TFT screen separately or putting in another panel.

If you want to see the majority of the Replicator torn down, I would recommend you follow International3D's writeup here, here and here. They have much higher quality photos than I can make, and my machine is a little less... picturesque than theirs. This will primarily focus on what they didn't focus on, like the front panel LCD. The purpose of this is to see whether or not I'm able to salvage at least some of the original boards, even with reduced functionality.
