First off - this looks amazing; I'd definitely buy a copy myself (even digital only). I'm going to have to follow your progress on this work!
Now - a couple of suggestions (and I realize this work is still in progress - so maybe these are being considered):
1. You mention Dungeons of Daggorath - so there's a few things I wanted to clear up:
Don't write "Tandy Coco" - the proper term for the machine of the era is the "Radio Shack TRS-80 Color Computer", and there were two main versions; version 1 ("TRS-80 Color Computer 1") was sold with a large gray case (it was originally based off of a machine Radio Shack sold to farmers for Telex information!) and version 2 ("TRS-80 Color Computer 2") with a white case (there are sub-versions within that version, but that's not important). Later, Radio Shack released the Color Computer 3, which looks similar to the Color Computer 2, but had a different keyboard, and vastly upgraded capabilities. However, it was -not- labeled as a TRS-80, but rather as the "Tandy Color Computer 3" - I am not sure of why that name change occurred, but it did.
Now - owners of the machine typically called it the "CoCo" (notice the capitalization - so CoCo 1, CoCo 2, and CoCo 3), but it was never referenced this way by Tandy or Radio Shack. Since Dungeons of Daggorath originally came out prior to the CoCo 2, it would probably be best to label it with "Radio Shack TRS-80 Color Computer" which is generally understood to refer to the original version of the machine, but can also represent the second version as well.
It should be noted here that for the Color Computer 3, a "sequel" to DofD (of sorts) was released, called "Castle of Tharoggad" (notice the spelling!) - but it was poorly received, and most fans of DofD don't like to talk about it.
2. On the Color Computer, there were more than a few other RPG games - for the CoCo 2, one of the earliest was "Gates of Delirium" by Diecom Products (1984) - it was somewhat of a clone of Ultima.
3. Later, the CoCo 3 had "The Seventh/7th Link" released by Oblique Triad - it too was similar to Ultima, but incorporated an interesting 3D system similar to Dungeons of Daggorath for the "dungeon" portions (IIRC). It utilized much of the CoCo 3's better graphics capabilities.
I'm sure I am missing some others in there (which if you are interested, I can dig in my archives for and see what I can find); the Color Computer is near and dear to me, as it is the machine I grew up with and ultimately led to me becoming a software engineer. I still have both of my machines (a CoCo 2 and a CoCo 3), plus all of my issues of the Rainbow Magazine. I keep in touch with a long running listserv with other members who own or love the Color Computer.
Lastly - and I haven't looked at the book deeply to know - I am interested in finding out what you cover on RPGs for the Amiga - there were a few lesser known ones on that machine as well (one - I forget its name - used an early first-person 3D system with flat-shaded objects - when it didn't crash, it was pretty neat to play for the time).
