    The original bonds and registration stubs are used to prove
    the accuracy of shipments from issuing and paying agents and
    establish alphabetic and numeric registration records to
    provide a status record of every United States Savings card
    bond printed. Alphabetic files are maintained by the name of
    the bond owner and numeric files are maintained by bond
    serial number to reflect the issuance and retirement of each
    bond. These records serve as search media to answer
    inquiries relative to card bond holdings and the status
    thereof. Reports are produced to reflect classified charges
    to the U.S. Treasurer's account and to provide the Division
    of Public Debt Accounts and Audit, Washington, with
    accounting data for the maintenance of outstanding savings
    bond interest accounts.

     roof of the building together with the motor generators,
     electrical panels, compressors, vacuum pump, and individual
     water tower. The compressors are situated on the 6th floor
     of the building. Power, water, and air lines come from the
     8th floor to the ceiling of the 5th floor. All such lines
     are suspended from the ceiling of the 5th floor and stub up
     through the concrete floor wherever necessary to feed the
      individual units. A free floor was designed and installed to
     cover all signal wires. Air conditioning is by package units
     which feed through ducts above the pan ceiling to various
     outlets. Package air conditioning units are equipped with
     steam to be used for either heating or humidity control.

                          ADDITIONAL FEATURES AND REMARKS
          Baltimore & Ohio Railroad Company Adopted procedures
       for magnetic tape labelling, storage, shipping, and
       protection from humidity, temperature and physical,
       electrical, fire, or other damage include generation of
       labels in computer program used for tape assignment, tape
       storage in closed file-type cabinets, and air-conditioned
       atmosphere for humidity and temperature control. First
       National Bank of Boston Outstanding features include
       exceptional reliability, very high error-free recording, and
       recovery of information on magnetic tapes. Unique system
       advantages include high capacity of tapes, 465,000 punched
       cards per tape (reel), hi)h speed, simultaneous read write
       (60,000 digits/sec., and ability to edit on off-line
       converters, saving CPU time. Michigan Hospital Service
      Outstanding features include large storage capacity of
     magnetic tape (37,200,000 digits per reel), read write
     magnetic tape at 60,000 digits per second, and three address
     instruction system (simplifies programming).
      Unique system advantages include system and instructions
     designed for data processing, particularly for low activity
     updating of large record files.
      Tape reels are numbered with ink marking pen. Data is
     labelled with Labelon Tape. Tape room is controlled for
     temperature, humidity, and dust. Security Tapes are stored in
     first floor lobby for 24 hour period. Security Tapes are
     alternated in warehouse storage on a semi-monthly basis.
BRL 1961, DATAMATIC 1000, start page 0216 

      Minneapolis-Honeywell Regulator Co.-TCG Division
     Outstanding features include 3" wide tape, orthotronic
     control, 900 lines per' minute printing speed. Tape storage
     is dust, humidity and temperature controlled. A distant
     vault is used for backup tapes.
       Treasury Department
      Outstanding features are (1) Transfer rate of 60,000
     decimal digits per second; (2) efficient and speedy
     sorting; (3) searches 10 tapes at once at transfer rate of
     600,000 decimal digits; (4) "OFF LINE" input and output;
     (5) built in air conditioning for central processor.
      Unique system advantages include (1) ability to read and
     search forward and backward and (2) Modulo 9 weight count
     checking system.
      Adopted procedure for magnetic tape labelling, storage,
     shipping and protection from humidity, temperature and
     physical, electrical, fire, or other damage include:
      Tape Labelling
          Reels are labeled with color code, name and run
       number(s). Dates, names and run codes are written on tape.
          Active tape records are stored on shelves in the
       Magnetic File area. Security tapes are stored in a vault
       in another building.
          Reels are placed in plastic bags and boxed in
       corrugated cartons cushioned with fillers.
      Protection from Humidity, Temperature, etc.
       Air conditioning and normal protection.
      The tape utilized in this System is divided into 36 linear
     recording channels. 31 of these channels are used for
     storing information. All other channels are used for control
     purposes. Data is arranged along the 31 information channels
     in arbitrary units called words and blocks. Each block
     contains a total of 62 information words. There are 52 bits
     in a word. Four are used for checking purposes and the
     remaining 48 may represent either numeric or alphabetic
     data. A word may be made up of 12 four-bit decimal digits, 8
     six-bit alphabetic characters or any combination of these
     adding up to 48 binary digits.
                                    FUTURE PLANS
          First National Bank of Boston There is a tentative
       plan to switch to Honeywell H-800 in 1962, when a third
       high-speed printer, a high-speed paper tape input, and high-
       speed MICR input (2 systems) will be added. Treasury
       Department Present plans are to carry out the program
       relating to punch card U. S. Savings Bonds established at
       the inception of the system, all available machine time is
       required. Plans are in a formulative stage to include the
       processing of Series E paper bond retirements abd reissue
       transactions as machine time is made available through
       improved programming techniques and liquidation of the
       backlog which antedates installation of the equipment.
