    NORDEN SCRIBE II

    NORDEN SCRIBE II 
    Scoring & Data Transcription Computer

    MANUFACTURER
    United Aircraft Corporation Norden Division

    APPLICATIONS
    System is used for special purpose data processing and 
    off-line scoring and transcription, with general
    applications to topologically equivalent systems.
    Similar to SCRIBE I with the addition of Magnetic 
    Tape output. Concurrent output from Card Punch and
    tape can be obtained as well as individually.

    PROGRAMMING AND NUMERICAL SYSTEM
    Internal number system      Binary Coded Decimal
    Decimal digits/word         Variable
    Binary digits/instruction    6
    Instructions/word Variable   1 to 3
    Instructions decoded        18
    Arithmetic system           Fixed point
    Instruction type            One address
    Number range                0 - 999
    Instruction word format     Variable

    Programming is identical to SCRIBE I with the 
    additional capability of modifying storage during run of
    sheets by insertion of a modification programming 
    sheet in the stack of data sheets.

    A wired program interpreting core memory is used. 
    The equipment is a special purpose data processor
    used mainly for the scoring and transcription of 
    answer sheets. It can be used for other topologically
    equivalent documents. It is programmed by scanning 
    an array sheet which is marked in accordance
    with the identification instructions and their addresses.

    A drum memory with 24 answer keys is used for
    automatically scoring as many as 6 different keys 
    indicated on an answer sheet.

    The sheet is arranged into 40 positions per row and a 
    maximum of 56 rows. The row arrangement is 8
    groups of positions.

    Magnetic Tape (RCA Model 581)         1,000 chars/sec
    Either card or tape or both can be operated simultaneously. 
    Tape will contain same 80 characters as
    card plus additional data.
