What about "random notes on interfacing to the IBM AT bus"? It is 
available from ;

Microcomputer Applications
P.O. Box E
Sulsun City, Ca., 94585

+1 707 422 1465

The description reads 'Describes adapter board dimensions, PC-compatible
and "new" bus signals, 8/16 bit data transfers, I/O port and memory
interfacing. Also describes the AT's added 16-bit DMA channels and additional
8259 programmable interrupt controller for interupt cascading."

It is $20.00 US. I have it, i was looking for more information on
constructing a board with a CPU and dual ported RAM available to the
board and to the AT. The book did not have this information, but i
remeber there being some detailed specs for the bus in it(i can't
find it right now.)
