If you look at the youtube channel "CuriousMarc" (just search for it, they have multiple restoration videos), you can look at this project in video, the latest video shows their attempt at finding the module's problem via XRay at the end, the other videos detail earlier parts of the operation, including booting up the AGC with original code fed from a ducttape-design FPGA/microcontroller. It's a very interesting video series to follow.
