A question for the techies.. A colleague asked me to enquire what experiences other designers have had with AT interface designs. Specifically, did you adhere to 1 wait state in 16 bit mode, 4 wait states in 8 bit mode (as per IBM refernce manual) ? If so, what IO access times did you get for a 12.5 MHz clock? E-mail replies are preferred for this one, he's not a regular reader, but he can have access to my mailbox. advTHANXance Dave E. (pp Chris)
