    Abstract: A text editing system which is completely comprised of magnetic bubble domain components (or charge-coupled devices) is described. The essential parts of the system are a passive storage comprising a plurality of shift registers which are a convertible structure, i.e., they can be randomly accessed or sequentially accessed depending upon the state of a plurality of conversion switches. This provides great flexibility in entry, retrieval, and restoring. An active storage comprising a plurality of shift registers is used for various text editing functions, such as insertion of data, deletion of data, etc. In the active storage, an editing shift register is provided which implements the various text editing functions using techniques such as freezing data bits and bypassing data bits in order to change the order of the data and to close gaps which may occur in the data. A write decoder is provided for selective entry of text into the passive storage and a read decoder is provided for selecting the contents of a specific shift register in the passive storage for data manipulation. The conversion switches are also used to control data flow paths or directions and to maintain the proper order of the data. Control circuits are provided to coordinate and control the functions of the various storages, the decoders, and the switches. The principles used for the overall system can be implemented with bubble domain devices or with charge coupled devices.

    Abstract: 1487121 Shift registers INTERNATIONAL BUSINESS MACHINES CORP 1 May 1975 [14 May 1974] 18157/75 Heading G4C To edit a text, a shift register storing a line of data bits representing text has a normal path 34 (Fig. 2A) and a by-pass path 36 so that the order of the bits may be changed, gaps in the data may be closed and data bits may be deleted. The shift register may be either a medium capable of supporting magnetic bubble domains in which case drive pulses for the register in the form of an unchanged repetitive sequence of drive pulses are provided by a rotating magnetic field or a charge coupled device in which case three phase propagation lines receive successive signals. As described the normal path includes a freeze and input/output position at which new data may be written by a write circuit (48, Fig. 2B, not shown), annihilated (in the case of the bubble domain embodiment by passing a large current through freeze loop (46)) or held whilst other data is shifted round the by-pass loop. The editing shift register (24, Fig. 1, not shown) is connected between the read decoder output from and the write decoder input to a plurality of shift registers (SR1-SRn) used for storing data text. A spare shift register (SR) is provided so that the contents of the shift registers may be interchanged.
