Okay, I've got more to say about the book...
There's a whole lot of non-ship stuff.
There are photos of the Duras sisters, TOS crew in 1986 SF, and more. There is a whole lot of text describing Archer's life story, missions of the Ent-B, and so on.
But the book is titled an "Owner's Workshop Manual"
I don't see how all this other stuff has a place here.
It's not supposed to be a nice book about Enterprises,
where crew history and missions and all that would be appropriate. It's an "Owner's Workshop Manual"! I would expect strictly technical text, yes?
TNG Tech Man is almost exclusively technical, as it should be. I would expect this book to be similarly written with technical details and specifications rather than the colorful history and crew adventures.
If I had an "Owner's Workshop Manual" for a VCR (yes I said VCR) I would expect details and specs for cable hookups and channel settings--not pages of the good times the family enjoyed watching "The Lion King" on tape, or how the industry decided to go with a particular remote control design instead of the other one.
So yeah, there are sections with technical details and all that, but almost half the text is non-tech history and backstory. It's not bad, but I don't think it was appropriate to this volume.
