  • Patent number: 4835739
    Abstract: A data storage system comprises a plurality of bubble memory chips each having a major loop and minor loops. At least one of the minor loops of each chip is used to store bad loop data for its respective chip. A system controller controls operation of the bubble memory chips. The system controller includes a chip controller for controlling operation of the bubble memory chips and a random access memory for storing the bad loop data from all of the bubble memory chips, and for supplying bad loop data to the chip controller so that data is placed only on operative loops of the bubble memory chips. A data transfer bus is used for inputting and outputting data from the system controller to a host computer. The system includes a plurality of bubble memory cassettes, each cassette having a predetermined number. Control signals are provided to the bubble memory chips of bubble memory chips so that more than one bubble memory chip is used simultaneously.

  • Patent number: 4300207
    Abstract: A multiple matrix switching system for use in connecting a unit under test to one or more external instruments which may either provide a signal input to the unit under test or measure the output of the unit under test is disclosed. Matrix switching allows connections between the unit under test and each external instrument to be effected with only two switching elements. Switching system control to select a signal path is accomplished by means of a microprocessor which resolves switching path conflicts through switching system status monitoring.
