Book

Hard Drive Bible: Book, CD, and Video
Martin Bodo
Hardcover
Published 1996 by Corporate Systems Center on Anvilwood Street (?) in Sunnyvale, California
ISBN: 096415031X , about $20

All the major interfaces are published in this book, which in its 8th edition last time I looked. This book is also good for IT and MIS types who have to do hard disk drive exchanges on computers, as every hard disk drive manufacturer -- and the model numbers for their products! -- are published in it. All in all, if you were ever looking for a book on IDE, SCSI or hard disk drives, this is the one book you want the latest edition of. It even comes with a CD of hard disk diagnostics tools that you'll find useful.

HDLC

High level Data Link Control is a standard communication link protocol established by the International Standards Organization (ISO). HDLC is the discipline used to implement ISO X.25 packet switching systems.

Is this new? No, Intel already announced a chip (the 8273) for it in it's 1978 databook. It's now used in the implementation of ISDN it seems. (Click on the advertisement above for more.)
