NORDEN SCRIBE II NORDEN SCRIBE II Scoring & Data Transcription Computer MANUFACTURER United Aircraft Corporation Norden Division Photo by United Aircraft Corp. 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. ARITHMETIC UNIT Construction (Arithmetic unit only) Transistors Arithmetic mode Serial Single bit adder is used, same as SCRIBE I. Timing Synchronous Operation Sequential

STORAGE No. of No. of Access Medium Words Digits/Word Microsec Core 600 17 14 Drum 784 40 17,000 The drum memory also contains two 480-bit recirculating registers for output buffering to card punch. INPUT Medium Speed Paper Sheets (8 1/2" x 11") 100 sheets/min (2,240 marking positions on each sheet) The sheet is arranged into 40 positions per row and a maximum of 56 rows. The row arrangement is 8 groups of positions. OUTPUT Medium Speed Punched Card (80 col Parallel Punch) 100 cards/min 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.
