I started doing one of my own focusing on the original series, animated and the motion picture. Add in a little from Enterprise and The Cage. Main focus, of course, on the original series.
I just started going through the various manuals with the FJ manual and Mandel's Officer's Manual as the keys. Even if I knew some things were later contradicted by later films/series, I kept a few apocryphal items.
Changing almost all illustrations with color. Keeping the fonts. Keeping the styles. But torn ... I want to update it, but like the old Enterprise, it has so much charm. On the other hand, I think about that one gizmo McCoy had that was clearly a 60s microphone and I cringe.
