multiprocessor microPDP-11/83

A post about a multiprocessor PDP-11/45 made me think about a multiprocessor microPDP-11/83. Is it possible to connect the Qbus of two microPDP-11/83s together? what about Unibus PDP-11/84s? The -11/83 is more interesting, because I can replicate it. Since bus arbitration is handled by the processor, arbitration on one of the processors would need to be disabled. The KDJ11-B Users Guide doesn't suggest a way to do this. The arbitrating processor would also have to field all the interrupts. I am tired of reading about the first computer on the internet... Besides, I have not heard any of you wise guys argue that there couldn't be a first computer on the internet (or Internet) or any network since a single computer can't make up a network. -chuck
