                The PDP-8/E
                featured the OMNIBUS -- a patented synchronous
                bus that handles bi-directional communication
                between system elements. A single OMNIBUS
                contained enough slots to handle up to 32K words
                of core memory, or up to 10 peripheral
                controllers. Shortly after the introduction of
                the PDP-8/E, DIGITAL installed its 10,000th
                computer system. |
