The command code interpretation varies, depending on instruction type.
The instruction word is divided logically into four sections, 
which are interpreted as a command code followed by three addresses.
Indexing. Each address in an instruction may be designated as an absolute 
address, indexed address, or indirect memory address. There are 
eight groups of eight index registers each, which may be used for 
indexed or indirect  addressing. There are also eight groups of 
sixteen general purpose registers each, which may be used for indirect
addressing. An increment, which is automatically added to these registers, 
can be indicated in an instruction.

 


Masking. The ability to mask words allows most internal processing 
instructions in the Honeywell 1800 Il to work with fields of 
variable length. Each program may designate a group of up to 
96 memory locations as masking registers. Such a designation 
may be changed by the programmer at any point in his program. 
Thus, an essentially unlimited number of masking registers is 
at his disposal.

Traffic Control directs the time sharing of main memory cycles by 16 
input/output trunks and the central processor.
Multiprogram Control directs the time sharing of the central processor by 8 
independent program control centers.
The H-1800 and H-1800-II, are identical except that the H-1800-II includes 
an Input/Output Control Center. This IOCC requires one input and an output 
trunk and is capable of controlling one card reader, one card punch, one
high-speed printer and four magnetic tape units. All of these peripheral 
units may be operated simultaneously, either on-line with the central 
processor or off-line, in any combination of operations. Any combination 
of peripheral units and their control units may be connected to the 
remaining trunks.

    APPLICATIONS
      Engineering office and small business office applications.
    The computer may be adopted to any specific application 
    within the scope of the machine's capability.

      For example, an on-line application where a customer his 
    several sets of input data which must be
    scanned in sequence or in parallel and then operated upon. 
      This, of course will dictate additional buffer
    registers which can then be used for other routines.
    The IN-15K general purpose computer is a machine 
    capable of the payroll, inventory, and editing
    function in a business application, and of the mathematical 
    routines of the engineering office. The HW-15K may also 
    serve as a rack-mounted version in special situations or 
    on-line applications in industry, or
    as a satellite computer in a large computer installation.

    automatic operation of the high-speed analog computing 
    capacility to permit iterative and sequential
    computation for a broad class of problems in many 
    fields of engineering. The logic, memory, conversion
    and input-output features extend the use of analog 
    computing techniques into new fields such as data
    processing and statistical analysis. The digital system 
    is also very effective as a simulator of digital
    controllers which may be used in conjunction with a 
    dynamic simulation of the physical system on the
    analog console.
    
       The HYDAC 2000 is composed of a general-purpose 
    analog computing console with a special control patch
    panel and a digital console composed of logic elements,
    memory units, analog-to-digital and digital-to-
    analog converters, plus a paper tape input-output 
    system. To provide the parallel operation required for
    compatibility with the analog computer, the digital
    elements terminate on a removable patch-panel
    similar to the analog console. This approach allows
    multiple channels of logical control and memory to
    communicate with the analog system simultaneously
    at very high speed. Analog computer portion is
    PACE 2318 V. Digital Operations System is DOS 350.

    Automatic built-in subroutines.

    A variety of subroutine programs have been written for 
    memory operations, and input-output. Routines
    for performing various arithmetic operations such 
    as multiplication and resolution have also been
    prepared. These sub-routines are patched on the 
    removable, storable panels of the digital console.

    Although the HYDAC 2000 system is not designed to 
    provide conventional stored program capability,
    arithmetic units are provided to supplement the 
    mathematical capability of the analog system. This
    capability is used both in a time-shared fashion 
    to reduce the use of analog elements as well as 
    a convenient means of performing simple arithmetic 
    operations in conjunction with other digital 
    programs such as function generation.

    ACCURACY AND RELIABILITY
    The accuracy of the analog plotter is 0.015 inches; 
    conversion of the digital data is within 4 counts,
    giving an overall plotting precision very close to 
    the width of the line drawn. High stability, wirewound
    resistors and silicon diodes are located in a 
    thermostatically controlled oven to give extra protection
    against changes in environmental temperature. 
    Analog operational amplifiers are chopper stabilized
    and, except for the tape transport unit, all circuitry 
    is transistorized for greater reliability.

    20,000 COUNT INPUT DATA RANGE
    The DATAPLOTTER plots up to 4-digit decimal numbers 
    of either sign, making its range effectively 20,000
    counts or +9999 to -9999. Front panel controls are 
    provided to permit plotting 1, 2, 3, or 4 digit numbers
    as desired. Scale and origin controls allow the plot 
    to be compressed or expanded from 1/3 of full scale
    to more than 10 times full scale and to move the data
    origin to a point either on or off the plotting
    surface up to 4 board widths, depending on the scale used.

    THREE PLOTTING MODES
    Two types of plots may be made with the standard 
    DATAPLOTTER: (a) Point Plots in which each set of X-Y
    coordinates are recorded as a point, and (b) Line 
    Plots in which successive X-Y points are connected by
    straight lines. As an optional feature the system 
    may be supplied with equipment to provide Symbol
    Plots, either as one of 12 automatically selected 
    symbols or with numeric identification of points. The
    VARIPLOTTER may also be equipped with a second 
    plotting arm for additional plotting versatility. When
    the second arm is equipped with a symbol printer 
    both pen or symbol plots can be obtained by the
    selection of the proper arm.

    PARITY CHECK
    Lateral parity check is maintained on selected 
    words to minimize the chances of error when data is
    being plotted from magnetic tape. By placing the 
    Parity Action switch on the Control Panel in the
    "Reject" position, the DATAPLOTTER automatically 
    rejects questionable data and continues plotting. With
    this switch in the "Stop" position, faulty data 
    causes the DATAPLOTTER to cease all operations so that the
    operator can examine the nature of the error and take
    appropriate action. The operator may decide to
    manually reject the data or to correct it by entering
    correct information with the Manual Data Entry
    Keyboard. After either of these actions are taken, 
    the plotter will continue to plot subsequent data.

    MAINTENANCE
    Trouble-shooting and maintenance are easily 
    accomplished on the Series 3440 DATAPLOTTER.
    All triggers and counters in the system are monitored
    by visual indicators. The keyboard may be used to 
    simulate the tape. In this mode all data detection,
    control and counting circuitry are utilized. All 
    digital logic and control printed circuit cards are mounted
    on rolling drawers for easy accessibility. Each of these 
    cards has color-coded phone jacks on its edge which
    allow safe monitoring of the output of all active 
    elements on the card. In addition, a Test Panel is
    provided which contains a selector switch for 
    monitoring any of the system power supplies with a self-
    contained voltmeter, and balance potentiometers for
    balancing the operational amplifiers.

    OPTIONAL EQUIPMENT
    Optional equipment is available for increasing the 
    plotting versatility of the Series 3440 DATAPLOTTER. This
    includes printing facilities for symbol or numeric 
    identification of plotted data, automatic incremental
    advance, paper roll mechanism and others.

    SPECIAL MODELS
    Variations of the Series 3440 DATAPLOTTER can be 
    provided on special order to accept magnetic tapes
    from other digital computers. A VARIPLOTTER with a 
    45" x 58" plotting surface is also available on special
    order.

    Magnetic Tape Format Definitions
        Character-consists of a group of bits placed in each
           of the seven channels on the tape.
        Record-a sequence of characters along the tape.
        File-a sequence of records along the tape.

    DIGITAL TAPE TRANSPORT
    The tape transport used with the 3440 DATAPLOTTER 
    is the Ampex FR400, which is designed for reading
    tape prepared by IBM 650, 704, 705, 709, 7070, 7090,
    1401, 1620, and CDC 160 and 1604 Computers. It is
    equipped with hubs for mounting standard IBM or NARTB
    tape reels using % inch wide tape. The tape is
    read at a speed of 75 inches per second with a seven-channel
    reading head to fit the dimensions of the
    recorded data. Manual controls are provided for controlling
    the tape reader in addition to the
    automatic controls that are required to carry out the automatic 
    plotting operations. Brakes are provided
    to automatically stop the tape in event of tape breakage or
    failure of AC power. Optionally available
    are stop devices which sense the IBM end of the tape foil markers.

    WORD & CHAR. SELECTION.    A record is first divided into 
    words of arbitrary size (from 2 to 12 characters)
    and the words into characters. The size of the word is 
    set on the Word Size dial. The location of the words
    to be plotted within the record are set on the X and Y 
    Word Selector dials. Any word from 000 to 159 can
    be selected. When plotting from magnetic tape, punched
    tape or serially fed punched cards it is
    possible to select the following characters from anywhere
    within the desired word: sign character,
    command character, thousands digit, hundreds digit, 
    tens digit, and units digit. These selections are
    accomplished by the use of six dials for X and six for Y. 
    The action taken on each record will depend
    upon the command characters which appear in the location 
    as set on the Command Character dials.
    Note that it is possible to set the Command Character
    selector to "0" in which case every X and Y word
    selected will be plotted.

    graphs are prepared at regular intervals, and as
    many as 100/mile of road depending on topography. Complete
    cross-sectional drawings for a typical
    mile of rural highway design -- a costly, time consuming 
    task -- can be plotted in 30 minutes with the
    Dataplotter Series 3500 System.

    

 



    Present day defense and space development programs 
    require many elaborate and complex test
    facilities such as missile ranges, wind tunnels, 
    and meteorological monitoring stations. Telemetered data
    from these facilities are produced in large quantities. 
    Missile trajectories and space vehicle orbits,
    determined through digital computations, can be converted 
    automatically to convenient graphic form.

    This system can be a valuable tool in reducing all such data to
    graphic form for faster, easier correlation and study.
    Contour lines and physical characteristics can be 
    plotted manually by keyboard or automatically with
    the Dataplotter 3500 System.
    A complete software program package will be available by September 1964.

    APPLICATIONS
    The HYDAC Series 2400 is a general-purpose, 
    combined hybrid, digital-analog-computing-system
    providing automatic operation of the high-speed 
    analog computing capability to permit iterative and
    sequential computation for a broad class of problems 
    in many fields of engineering. This system is a
    particularly powerful tool for aerospace problems 
    where the high accuracy requirements are low
    frequency control calculations can employ less 
    accuracy. The combined capability is very effective in
    determining optimum trajectories since this type of 
    problem requires may rapid solutions of the trajectory

    memory, conversion and input-output features extend
    the use of analog computing techniques into new 
    fields such as data processing and statistical analysis.

    The digital system is very effective as a simulator 
    of digital controllers which may be used in conjunction
    with a dynamic simulation of the physical system 
    on the analog-console.

    The HYDAC 2400 is composed of a HYDAC 2000 with 
    additional data and control linkage units in the

    with a DDP-24 general purpose digital
    computer manufactured by Computer Control Company, Inc.

    The HYDAC 2000 contains a general purpose analog 
    computer (PACE 2318-V) with a special control
    patch panel and a digital operations console (DOS 350) 
    containing logic elements, memory units,
    analogdigital and digital-analog converters plus a 
    paper tape input-output system. The parallel-
    programming digital console acts as a flexible, 
    programmable linkage system providing the control,
    timing and analog-to-digital and digital-to-analog 
    communications for the entire combined simulation
    capability. This type of control is essential for 
    the effective utilization of the powerful analog and digital
    computing capability for iterative or sequential programs.

    To provide the parallel required between the
    digital and analog computers the digital elements 
    terminate on a removable patch panel on the DOS
    350 similar to the analog console. This approach 
    allows multiple channels of logical control and memory
    to communicate with the analog system at very high speed.

    Although the HYDAC 2000 section is not designed 
    to provide conventional stored program capability,
    arithmetic units can be provided to supplement 
     the powerful mathematical capability of the analog
    system. This capability is used both in a time-sharing 
    fashion to reduce the required number of analog
    modules as well as a convenient means of performing 
    simple arithmetic operations in conjunction with
    the digital programs such as function generation. 
    Of course, most digital arithmetic operations of the
    HYDAC 2400 are performed by stored program in the 
    DDP-24, but where high-speed, continuous
    operation is required, the HYDAC 2000 assemblage is used.

    Service lines, output control lines, interrupt lines 
    and 24 input-output data lines from the DDP-24 are all
    controlled from the pre-patch panel of the DOS 350. 
    Through this patch panel the DDP-24 can control all
    of the available functions of the PACE 2318-V console.
