Besides the other books mentioned, there is the IBM PC/AT
Technical Reference manual and a book titled (something like)
"ISA and EISA Bus Handbook" by Ed Solari.  The second is
available from Annabooks, 11848 Bernardo Plaza Court, Suite
110, San Diego CA 92128.


If you're doing prototyping or low volume, you might look
at a card & parts kit with address decode already done.

JDR Microdevices (south San Francisco bay, like San Jose)
has both 8-bit and 16-bit kits.  The printed circuit card
is the right form factor, has the edge fingers to plug into
the connector, and some real estate dedicated to a pre-wired
address decode circuit.  Rest of card is .1" grid of holes
for your circuitry.  They have a seperate kit of IC parts to
do decode & buffering.  Total cost is $50.
