Computer System Organization: The B5700/B6700 Series

For any use of the Unisys A Series/Clearpath systems that desires some deeper knowledge of how these systems were designed, I highly recommend this book.This book gives a complete presentation of the major operator and stack architecture elements. While much of the information is no longer valid for the current architectures, the basic PCW, RCW, MSCW words are there in theory, if not accurate for today's systems. This book gives a good insight into the reason that ALGOL screams on these systems. I highly recommend this book for all support or systems persons on the A Series or Clearpath NX systems.
