I highly recommend a book called 'AT Bus Design' by Edward Solari.  It is
published by Annabooks.  The ISBN # is 0-929392-08-6.  It has timing diagrams
and info for 8 and 16 bit ISA, E-ISA and EISA designs.  I bought this book
several years ago (it was published in 1990) and have used it quite often to
success.  Good luck.
