Programmable Option Select Card Selected Feedback System Board Setup Adapter Setup Adapter POS Implementation POS Implementation Procedure System Configuration Utilities Adapter Description Files Micro Channel Adapter Design Dimensions Power Voltage Regulation General Design Considerations Design Guidelines I've left out some of the headings to save typing...I just wanted to give you a flavor of what's in the book. There are timing diagrams and adapter drawings (with dimensions). I can't comment on the accuracy and completeness of the info because I'm not a hardware hack. -- Andrew Ernest
