ABSTRACT:
A data handling apparatus of solid state construction for a data processing system. The apparatus has a storage and input/output gates for peripheral units. The storage includes input and output counters for generating storage addresses which, respectively, determine a location for useful data to be temporarily stored while in transit and a location to which such data is to be emitted. The counting modes can be switched to accomodate connecting two or more units of the data processing system. A comparator is connected to the counter outputs and produces therefrom an indication of the state of occupation of the various storage locations.
