- Andreas,
-
- The specifications for the UNIBUS and the QBUS used to be
- published by Digital in the handbooks for the different product
- lines. There was also a little handbook which contained both
- specifications, called the "Bus Handbook". However, all of these
- books have not been printed in years (I keep my copies under
- "lock and key" because I need them).
-
- Some information on the bus structures was published in "Computer
- Engineering: A Digital View of Hardware Design", by Bell, Mudge
- and McNamara, but the handbooks (particular the Bus Handbook and
- the Microcomputer Processor and Interfaces Handbooks for the
- LSI-11 series) went into the extremely low level details of the
- bus structure and implementation.
-
- I hope that the above information is helpful. If I have been
- unclear, or if I can be of further assistance, please feel free
- to contact me via Email.
