    ADDITIONAL FEATURES AND REMARKS
    The CCC 6F2 Trainer is equipped with a large display panel,
    containing the system block diagram and indicator
    lights for demonstrating computer organization, flow of
    information and order control. Typical computer
    malfunctions can be inserted in up to 246 circuit locations. 

    This is accomplished by means of remote fault
    insertion controls accessible to only the instructor. 
    Students learn computer maintenance procedures and
    programming on a machine specifically designed for 
    instructional purposes but also capable of performing realistic
    data handling functions. The Clock Selector Switch permits 
    the instructor to select one of four computer operating
    speeds. Normal speed is comparable to operational computers. 
    Slower speeds aid in demonstrating fault location
    techniques, and allow computer operations to be visually 
    observed through the indicator lights on the display
    panel.

    of field operating experience based on failure reporting 
    program, technical notes on system hardware
    modification, technical notes on programming modification, 
    spare parts provisioning, and stocking of programming
    forms and paper tapes are provided.

    Installation service of up to one week is provided with each DDP-19.
    Programming, maintenance and systems engineering services 
    are available on a contract basis.

    PERSONNEL REQUIREMENTS
    One operator and one engineer are required.
    Training made available by the manufacturer to user includes
     operation and maintenance. The programs having
    once been prepared are utilized without need of further 
    programming unless the computer is to be used for new
    and different modes of operation. Since the existing 
    programs meet the present system needs, no current
    programming effort is utilized.

    RELIABILITY, OPERATING EXPERIENCE
    System features and construction techniques utilized by 
    manufacturer to insure required reliability includes
    completely transistorized and modularized construction. 
    Package types are limited to 8.   98% of the systems
    utilize 4-package types.

    ADDITIONAL FEATURES AND REMARKS
    Outstanding features include a fast hardware multiply-divide,
    modular construction, independent memory, unlimited expansion
    of I/0 channels, a degree of modularity and large scale orientation.
    DDP-19 is a solid state, core memory, parallel serial 19-bit 
    word, binary, single address, stored program, general purpose
    computer, with indexing and indirect addressing.

    Sign-magnitude machine code is used for maximum convenience 
    of operator and programmer. DDP-19 is capable of up to 100,000 
    computations per second, communicates with peripheral equipment 
    with a minimum of external decoding. Input and output can
    occur asynchronously and be interleaved with processing at 
    transfer rates up to 166,000 words per second.

    Ease of DDP-19 programming is assured. Command structure is 
    flexible, simple and straightforward; oriented to
    real-time applications. A complete programming package, 
    including a Fortran II compiler, an assembler and a
    scientific programming system specifically designed for 
    the minimally experienced user are included with the DDP-19,
    as well as comprehensive utility, service, and executive routines. 
    Programmer and maintenance training, a logistic, support program,
    and installation services are part of the DDP-19 user support program.

    The DDP-19 is a high-speed computer due to the basic machine 
    cycle of 5 sec and powerful command structure.   Yet its internal 
    organization allows for moderate-speed circuitry. This in turn
    provides the wide performance margins and reliability of the 
    DDP-19. No critical timing problems; easy addition of peripheral 
    equipment is possible.

    The DDP-19's combination of modular design and an extensive 
    selection of input-output options and peripheral equipment 
    permits nearly unlimited expansion at modest cost. 

    Interrupt lines, a multilevel priority system,
    buffered input-output channels for parallel and character 
    transfer can be added as required. Ready and interrupt
    modes enable the computer to be used in any system or to 
    control subsystems. Fully buffered input-output
    control units with priority memory access and modular 
    memory banks provide true simultaneous real-time input-
    output and continued computation. Integral control 
    matrices minimize external decoding and controlling
    hardware.

    The complete standard DDP-19 is contained in a single

Registers and B-Boxes
Arithmetic Unit. This consists of the A-register, 
B-register and Adder. The Z-register may also be 
considered part of the arithmetic unit at certain times.
A-Register. The main arithmetic register of the computer.
B-Register. The auxiliary arithmetic register.
Z-Register. A 24 bit register receiving its information 
     from the memory. After a command fetch 
     the 14 least significant bits contain the address 
     of the instruction, or the 14 bit operand in some 
     cases. After an operand fetch the Z-register contains 
     the operand and then is to be considered part of the 
     arithmetic unit.
ADDER. The logic structure providing for sums or 
     differences during computations.
CONTROL UNIT. This consists of the program counter 
     (P-register), op-code register (0-register), 
     index register (Xregister), shift counter (S-register),
     transfer bus, AU bus, and control unit clock. 
     In addition, the Z-register can sometimes be considered
     part of the control unit, sometimes part of the arithmetic 
     unit. The functions of these registers are: 
PROGRAM COUNTER. (P) Contains the memory location of the next
     instruction to be performed. Normally its contents are 
     incremented with a ONE each time a new command of the 
     computer program is fetched out of memory. In case
     of a transfer in the program the program counter will 
     be filled with the memory location to which the program
     shall transfer. 
OP-CODE REGISTER. (O) Contains the 6 bit op-code for the 
     instruction being performed, the index bit and the indirect 
     address bit. 
INDEX REGISTER. (I) If the index register is specified 
     by an instruction, its contents are added to the address
     of the instruction and the result becomes the effective address. 
    (There are a few instructions, such as scale and normalize, 
    where the index register is used in a slightly different manner, 
    as here under described with these individual instructions.) 
SHIFT COUNTER. (S) This is used with the shift instructions, 
    indicating the number of shift steps. 
Z-REGISTER. (Z) Permits arithmetic operation to overlay 
    I/0 operation in some circumstances.
There are 3 index registers which may be incremented, replaced 
or cleared and are capable of modifying either address under
 control of two index control bits located in each instruction.

The tape unit is connected to a word forming buffer.
   The buffer communicates with the computer in 24 bit words.
   These words are separated into 6 bit characters and
   parity is assigned (or checked) according to the IBM convention 
   of odd for binary and even for BCD. The number of characters
   per 24 bit word is selectable under program control. 
   OCP commands are used to select parity, characters per word, 
   and initiation of a read or write operation. The word forming 
   buffer will communicate with the FBC. The tape system will
   have an interrupt line to the computer. 
Characteristics of the Tape Unit are:
Tape speed                   45 inches/second, forward and reverse.

Memory is organized in four blocks of 4,096 words. Most orders reference 
locations within present block (as determined by location counter but 
certain orders called "Universal Orders", divide word as 6 bit op. code
and 14 bit address and may address all of memory as a single contiguous 
block of 16,384 words.

Twos complement arithmetic is used. Floating point is programmed. There are 
no automatic built-in subroutines.

Automatic Coding  
   SAE - Symbolic assembly routine  
   EERIE - Symbolic interpretive routine  
   ALGOL - Algorithmic compiler
Registers
  A Register   an accumulator
  B Register   quotient
  N Register   number
  X Register   saves location counter for return  branch
 R3 Register   order

Provision is made within the order structure for magnetic tape, but no 
units are in use. If units were connected they would be IBM 727's 
with IBM control unit.

INPUT
Medium Speed
Paper Tape                  500 chars/sec
Typewriter (Flexowriter)     10 chars/sec
A one character buffer appears between the photoreader and the computer. 
This permits 2,000 microseconds of computing between characters 
and permits manual correction of parity errors. 
Eight-level paper tape is used. The photo electric reader is of local design.

OUTPUT
Medium Speed
Paper Tape                    75 chars/sec
Typewriter (Flexowriter)      10 chars/sec
A 64-word, 46-bit magnetic core memory buffers the machine from the output 
device.
