Thank you to users 240260280z, bglaesmann, and Captain Obvious.
I digitized the 1978 FSM. Cover is created by bglaesmann and the FSM was submitted by 240260280z. I consolidated all the files into one pdf and adjusted the numbering scheme to match the manual. The text is searchable and most of the important sections and subsections are linked and bookmarked for easy navigation on a tablet or smartphone. The color coded wire diagram submitted by Captain Obvious is included as an attachment. Hope it's helpful.
