Ah, just a bunch of fun highlights from the novel:
Page 14
However, given the surface-to-vaccuum defenses, the number of fighters, turbolaser batteries, charged-particle blasters, magnetic railguns, proton torpedoe banks, ion cannons, and a host of other protective devices , no naval ship of any size would be even a remote threat.
This implies that it VASTLY outguns any ship that ever existed. Ironically it seems to also take the same page out of the ANH novel and Radio drama, by implying that far MORE weapons types than just turbolasers and ion cannons were present on the Death STar. This may be an effort to explain away the apparent tiny numbers.
Also note that ion cannons and "charged parrticle" weapons are treated as not being the same thing.

White-glove a surface in any of the six turbolaser turrets or two heavy ion cannon turrets, and there wouldn't be a speck of dirt.

You didn't get to shoot the big guns unless you had plenty of practice shooting hte little ones.
As we can see, the authors decided to adhere to the DK book's description of ISD armament rather than the WEG/WOTC sources. This may well be a first. Though they do still stick with the "Imperial' and "Super-" class nonclemature, but I guess you can't have everything.

Tenn hoped to be transferred, one day, to one of the four new Super-class Star Destroyers that were currently being built. Those were monsters indeed, eight or ten times the size of the Imperial-class ships, which were themselves over a kilometer and a half in length. The SSDs looked like nothign so much as pie-shaped wedges sliced out of an asteroid and covered with armament. Perhaps if he called in the right favours at the right time, he might wrangle an assignment on the next one scheduled to roll ponderously out of the Kuat Drive Yards. He still had a few good years left in him, and who better to run the big battery on one of those monster ships than him?
The aforementioned "eight to ten times" sized SSDs that cannot be Executors. Note that "size" is a bit vague, it could refer to mass/voluem or length, but the context here seems to imply length, meaning that these vessels would be somewhere between 12.8 and 16 kilometers in length.
Its also worth noting that the implied appearance of the ships look more like ISDs rather than the Executor (no fantail is mentioned), which may further reinforce the distinction.
Likewise, it is interesting to note they are KDY designs, but that it implies it is not a new class and that ships of this type already exist. Tenn mentions that "four new" SSDs are currently being built, but he then later mentions "The next one scheduled to roll out" from KDY, which as I said indicates that vessels of that type are already in servicec. We cannot say how many, but the low numbers being built (four or so) would perhaps suggest there are either aren't very many, or there are too many.
Its also possible these are Mandators, although that's unconfirmed.
Lastly, it is worrth noting that Tenn also figures that these ships carry similar-sized "big turret" type armaments like ISDs,

Tenn was looking forward to hearing the generators whine as the capacitors loaded, followed by the heavy vibrations and scorched-air smell as the ion cannons and lasers spoke, spewing hard energy across empty space to destroy the practice targets.
The mention of capacitors is worth noting, because it reinforces the notion that ISDS and other warshisp can direct nearly all their reactor output into weapons (This has been called into question before, and its worth noting how a capacitor is meant to work.)
Liekwise, the authors seem to go with the idea that ion cannons ARE capable of inflicting physical damage, ,rather than behaving how WEG claims they do (disabling ships, but no physical damage.)

If it didn't work - well, the hypermatter reactor was capable of generating an energy burst equivalent to the total weekly output of several main-sequencee stars;l if anything went ownky, it wasn't liekly he'd be around long enough to notice.
The power generation capability of the DS's hypermatter reactor. Already discussed.

His nephew, Hora Graneet, had been a navy spacer on the Imperial-class Star Destroyer Mark II class vessel, which had been selected for a shakedown cruise testing one of the improved prototype hypermatter reactors. Tenn didn't know the specifics of what had happened, and didn't have anything close to the math needed ot understand it anyway. He knew that hypermatter exised only in hyperspacec, that it was composed of tachyonic parrticles, and that charged tachyons, when constrained by the lower dimensions of realspace, produced near-limitless energy. How this "null-point energy" had become unstable he didn't know. He only knew it had been powerful enough to turn an ISD-2 and its crew of thirty-seven thousand people into floating wisps of ionized gas in a microsecond.
ISDs carry hypermatter reactors. It also suggests that Mark 2 ISDs (or some type of Mk 2 design) existed some time prior to Yavin while the Death Star was being built.
The power generation comments are interesting. The refrence to "near limitless energy" and "null point energy" would seem to point to some sort of "hyperspace tap" concept (or at least some form of external power draw.) One might infer that the authors believe that Hypermatter reactors behave somehow like a 40K plasma reactor or a Stargate Naquadah reactor.
The other interesting power-generation tidbit is that the ISD was reduced to "ionzied gas" along with its crew in a "microsecond."
Assuming iron construction and roughly 90% empty space, an ISD could mass around 40-50 million tons or so (disregarding fuel). Vaporizing that much iron would require around 4e17 joules of energy (~100 megatons) - the crew are a minor parrt of the calc. The ISD is vaporized in a microsecond, which means that 1/1,000,000th of its output was transferred into the ship (at least) This would roughly point to an output at least in the e23-e24 watt sustained reactor output (at least 4e23 watts.)
This is conservative, though. "ionized gas" would imply reducing the ISD to some sortt of plasma state, which suggests a considerably higher temperature. (tens of thousands, possibly millions of degrrees instead of thousands.) In any case this would suggest ISD power generation being roughly consistent with how it is shown in the DK books for other vessels (IE venator) as well as what Curtis himself has estimated.

In addition to the best military wards and pyrowalls, the folder was also protected by a random number generated by a quantum computer, said number being forty-seven digits long. Moreover, the program would shift each digit one value lower or higher every six standard hours, and only somebody with the code to access the program running it could keep track of this shift - one had to know the date and hour the program generated the number in order to follow the seequnece.
More fun Imperial computer technology, this stuff dealing with passwords and encryptions. Note the use of a quantum computer.

..he was working out in the exeuctive officers' heavy-gravityroom, which he'd set to a three-g pull. Just standing in such a field was an effort. Every movement required three times the energy it normally did.
...
Motti picked up a trio of denseplast workout balls, each the size of his fist. Anywhere else on teh station whtey would weigh about a kilo each; in the HG room they were three apiece. Juggling them caused his muscles to quickly burn.
...
..and the first thing he had learned when juggling in the HG room was to move his feet out of hte way quickly if he dropped a ball. Three kilos moving at three times faster than normal could easily break bones or crush toes.
Admiral motti training out in a "Heavy gravity" room. He does not seem to be discomfited by training under three gees (and the fact that Officers have access to such training areas suggests that heavy-gravity training is not unusual in the navy. Which in turn suggests its not unusual elsewhere, such as the stormtrooper Corps.)

abruptly his pursuer's ion cannons flared. White light filled the cockpit, and as it blinded Vil, he heard:
"Your ship has been destroyed."
This was simply a simulator training session, but it is worth noting that yet again, ion cannons are indicated to be destructive weapons.
Page 179
Of current-duty Imperial pilots, you are currently ranked nineteenth in this simulation."
Hmmm. "Out of how many?"
"Two hundred and thirty four thousand, six hundred and twelve."
This implies that there are at least a quarter million pilots on the Death Star. Whether this is purely TIE fighter pilots (possible, given that the guy running the simulator, the aforementioned Vil Dance is a TIE pilot doing a combat simulator) or includes others is not specified. I thoguht it was worth noting at least.
Page 183
"The station is a fortress. It has more guns than a fleet, and a weapon that will crack open worlds like the were ripe Wuli nuts."
This implies the Death STar's total number of guns exceeds the number of guns in a "fleet", however one chooses to define this (more than tens of thousands or hundreds of thousands of guns, perhaps.)
Page 224
Construction on the station kept getting faster as crews learned from the first sections built and were able to build new ones with less wasted effort. Some parts of the process had been so streamlined that the work went nearly twice as fast as it had before. The army of construction droids worked tirelessly, day in and day out; an interior structure that would ordinarily take months to finish with organic labour would often be completed in only a few days.
...
The only ones who caime close to matching the droids' speed were the Wookiees.
Comments on automated vs organic construction technology. It is worth noting that despite using slave and criminal labor, they do seem to make extensive/heavy use of automation to actually build the thing. The organic slave labor either is for helping to run the machines, partt of the design/engineering process, or perform some specailist task. Which is consistent of their portrayal in the book.

Then again, military secrets were notoriously hard to keep, and a file could be transmitted across the entire galaxy, given enough power in the generating signal.
Range of FTL communciations, presuming "sufficient energy" (it is suggested the Death Star would have s ufficient energy for this feat.)

"If Tarkin even thinks there's a rebel base on a planet or moon - " Nova moved both hands in a motion simulating the flowerign of an explosion. "Boom. End of base, end of problem. Two or three worlds go up in a flash like that, ,and the war's over. Who would risk losing billions or even trillions of people to hide a few insurrectionists?"
Suggestion here that there are planets with "trillions" of people.

It took no more than an instant. Tenn knew that the beam's total destructive power was much bigger than matter-energy conversion limited to realspace. At full charge, the hyper-matter reactor provided a superluminal "boost" that caused much of the planet's mass to be shifted immediately into hyperspacec. As a result, Alderaan exploded into a fiery ball fo eye-smiting light almost instantaneously, and a planar ring of energy-reflux - the "shadow" of a hyperspatial ripple - spread rapidly outward.
The much-contested destruction of Alderaan by the Death Star in the novel. Note that the Hypermatter reactor is noted to give the planet's mass a superluminal "boost", suggesting it pushed the planet's mass physically into hyperspace, which may hae helped facilitate its overlal destruction.

He managed to get the spin under control and then ready the little ship for the jump to lightspeed. A second or two would be enough. A couple of light-seconds would put him more than half a million kilometers away and give him a chance to get the TIE under control.
Vader's TIE performs a sublight hyperdrive "jump", much like the Falcon did in Hutt Gambit, ,and Boba Fett's Slave-1 did in "Bloodlines" This ought to be indicative of many millions of gees worth of effective accecleration.
