    APPLICATIONS
    Guestron is a real-time, on-line, system for 
    customer transaction capturing, accounting, and billing for
    hotels, motels, hospitals, and other institutions.

    PROGRAMMING AND NUMERICAL SYSTEM
    Internal number system      Binary coded decimal

    Decimal digits/instruction   1
    Arithmetic system           Fixed point
    Instruction type
     Wired and plug board program.
    Number range                 7 decimal digits
    Instruction word format
      Instructions are built-in and have various formats. 
    Automatic built-in subroutines
      Many complex subroutines are designed into the machine.
      These are initiated and selected by elemental external events.
    The system is a special purpose system with a fixed built-in program.

    COST, PRICE AND RENTAL RATES
    The purchase price varies from $50,000 to $150,000
    per system.
    A complete maintenance contract is available from
    the Laboratory for Electronics, Inc.

    PERSONNEL REQUIREMENTS
    From 3 to 20 Input-Output operators may use the system.
    Training is made available by the manufacturer to
    the user, however, only a minimum of operational
    training is required.

    The system is designed for continuous unattended
    operation. All operators have non-system job function
    and utilize machine as an automation device.

    RELIABILITY, OPERATING EXPERIENCE
    The system is designed on a modular basis for
    continuous unattended service. A marginal test
    feature is designed into the equipment which allows
    a thorough check of system condition on a daily basis
    by operating personnel. Routine weekly preventive
    maintenance reduces in-service failures.

    ADDITIONAL FEATURES AND REMARKS
    Outstanding features include high operating speed,
    simplicity, flexibility, ease of maintenance, low
    operating cost, simplicity of input-output equipment,
    flexibility in number of accounts which can be
    serviced and availability of an account auditing
    program.
    The system is designed for unattended use in non-
    air conditioned office space.

    RELIABILITY, OPERATING EXPERIENCE
    The modular design of this system exists at several 
    levels. It has the ability to replace a failing group,
    subsystem or assembly dependent on failure location. 
    These are all solid-state data processing elements.
    System programming, logical design, and equipment 
    configuration all spell reliability. The use of 60 data
    processing checks (i.e. flip-flops) further 
    enhances system reliability.

    ADDITIONAL FEATURES AND REMARKS
    Outstanding features include real-time, on-line data 
    communications and display, modular real-time,
    input output data transmission processors, arithmetic, 
    logical, decision, control change, storage and
    input/output, mass memory and index registry commands, 
    realtime indicator, nanosecond clock time,
    interrupt for input/output, data transfer check, 
    diagnostic program, multiple errors, error correction
    completion, inquiry facility for display console, 
    program search, and interfaces with digital data links.

    Operations applications meet military requirements.
