I actually have a bit of mixed feelings about some of that stuff. Specifically, when the "Ship Operator's Manual" first came out I thought it was really interesting and well done, but over time I'm not so sure that it has held up all that well too me.
I still think the SOM is fantastic. Sure, there are differing opinions on how things work in the Traveller universe, but the SOM was the first book to tackle it all, put it in one place, and delve into real detail.
For those who've never see DGP's Starship Operator's Manual, this was a MegaTraveller publication that looked at each major system on a starship and described it in detail, from the Jump and Maneuver Drives, to the ship's computer, to the communications system, to the major sections of the ship (Bridge, Engineering, Hold, Staterooms, Common Area, Corridors, Airlocks, etc), sensors, Weapons....you name it.
The book even provided connection diagrams which I've used several times in games where players tried to cut into a bulkhead and disconnect or override some system or other.
It's a fantastic, amazing book.
I think not too long ago I had posted some stuff on how the image of the "Oldtimer" was just a modified image of Adm McCain from WWII, how the deck plans for the Free Trader were grossly oversized, and how the description of a "jump grid" seems to have ultimately added unnecessary complexity and conflict with other canon stuff.
I think most RPG pubs have problems like these. I don't know why, but they exist in supplements for just about every game I own.
On the whole, though, the SOM is a winner, even if you don't agree with the "jump grid", the Maneuver Drive "overdrive", or the thought of Thruster Plates.
I dig it. I like the psuedo-science. It doesn't have to be real for me. I buy it if it sounds real enough--just like buying the idea of Jumpspace.
I haven't read the sections yet, but it is interesting that T5 does devote some chapters to these types of questions, and I did see that Jump Grids were included--but the J-Grids are just one method among a few for a starship to create a jump bubble around the ship for transition to J-Space.
So in the end I kind of like some of the stuff, but I'd suspect that I'm probably not quite as "enamored" of their stuff as others might be.
Consider me "enamored".
I especially like the descriptions of the different types of control panels. Before the SOM, I really wasn't sure what a "holo-dynamic-linked" panel was.
