I'd also suggest checking out CuriousMarc's channel who is involved in restoring what I believe is the same AGC and has a bunch of very interesting videos about it (among other antique computing gear like teletypes and a Xerox Alto): https://www.youtube.com/user/mverdiell/videos.
Speaking of AGCs, he just recently uploaded a video where they used a restored AGC to dump prototype core rope memory modules from the Computer History Museum's (non-functional) AGC.
