ABSTRACT:
A data entry system having a plurality of data entry key stations each having its own inexpensive, random access magnetic storage device with removable media and visual display connected to a common shared processor. Data characters of data records which are entered at the key stations are transferred to the shared processor and then transferred to a data buffer memory and to the visual display character by character. Data records assembled in the data buffer memory are transferred to the magnetic storage devices to provide a semi-permanent record file which is transferrable to a host processing unit.
