Thanks. > >Technical Reference >Personal Computer AT > >Order #6280070 from IBM > The IBM Technical Reference Manual most definitely does NOT contain the hardware specification for the AT BUS. It does contain pin outs, but by no means does it contain a hardware description or timing diagrams. I would hate to see the requestor shell out $100.00 for this document only to find out that it isn't what he asked for. The following is a message that I typed in many months ago. I kept it as a file to merge into other messages...just like this one. In a recent posting, I saw a request for the ISA BUS timing specs. At the time, I couldn't find anything, but here is the information for a book regarding the ISA BUS and its timing specs. "AT BUS DESIGN" by Ed Solari. Annabooks 12145 Alta Carmel Ct., #250 San Diego, CA 92128 (800) 462-1042 $69.95 + S&H -- "Worship the Lord your God, and serve him only."
