Sorry for the confusion, I must have misunderstood when I read about those network devices. Though I suppose what I want could be considered a form of point-to-point communication. > What devices are going to be connected to all of these Unibus(s)? It's mostly used to allow direct access to PDP-11 main memory. Maybe a longer explanation is in order. The MIT AI PDP-10 had a special device attached called the Rubin 10-11 interface. It allowed connecting up to eight PDP-11s. The interface mapped the PDP-11 memories into the PDP-10 address space. As far as I know (there's not much in the way of documentation), there was only shared memory, no interrupts or any other features. The PDP-10 always initiates accesses. The 11s could not access PDP-10 memory. _______________________________________________ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
