I asked this same question (details on the Model 100) just last month.
Here is a sumary of what I was told.
You might want to try _Inside the Model 100_ by Carl Oppendahl.  It is a
very well-written text on the inner workings.  It is oriented more toward
the hardware aspects of the machine, but it has lots of ROM openings, too.
 
You could hook a machine language program
to the "very often" routine (a hook out of the background task) described in
_Hidden Powers of the TRS-80 Model 100_ by the Waite Group.  It may also be
described in _Inside the..._, but I haven't looked.

   I got a lot of technical information on the Model 100 from Carl
Oppedahl's "Inside the Model 100"rn{, published by Weber Systems,
$19.95, 8437 Mayfield Rd., Chesterland, OHIO 44026 (I can get the number
if you want it).  Excellent book.  It's the most complete tech book on
the M100 that I've seen.
