SCSI Encyclopedia Phases & Protocols A-M (ENDL SCSI Series)

Volume I A-M deals with the principles of operation of the parallel physical interface. Everything to do with bus phases, timings, the protocol, command queueing and dozens of other subjects are covered in depth.
The Encyclopedia divides information by subject matter to describe how SCSI works. The emphasis is on comprehension, and serving as an in-depth source for neophytes and experienced users alike.
This volume took several years of effort, and presents the knowledge gained from designing both chips and products.
