World's Thickest Book

Intel should publish all of their documentation, including

http://www.intel.com/content/www/us/en/architecture-and-technology/64-ia-32-architectures-software-developer-manual-325462.html
and
http://www.intel.com/content/www/us/en/architecture-and-technology/64-ia-32-architectures-optimization-manual.html

in one book.

The 376 didn't fail because they eliminated real mode; it failed because it didn't have paging and thus remained incompatible with a garden variety 386 even after it had booted.

The embedded market has always been wary of Intel pushing weird crap, and history has consistently upheld their skepticism. You may point to the 386EX as a success story, but every ODM that went with that chip got burned because Intel was disinterested and provided no upgrade path for them.
