Instruction word format
The command structure of the 304 system is unique in a
number of aspects. The instructions are basically 3 address plus a
number of other functions or capabilities that are built into the
execution of the instruction. The basic instruction word format
for arithmetical operations such as add, subtract, etc., is
illustrated:
9 8 7 6 5 4 3 2 1 0

C = Putaway or Jump Address
V = Variation.& Self-Linking designator
M =Auto-monitor level
S =Combinations of A, B, or C to be relative to
Index Register
R = Index Register
A1, Ar = left and right field of A Address
B1, Br = left and right field of B Address
C1, Cr = left and right field of C Address
The programmer in translating procedures for the 304 System
will use the NEAT (National's Electronic Autocoding
Technique) format. The programmer might write the following
to add the Old Quantity on Hand to the Number Received to
arrive at the New Quantity on Hand:
ADD (V) (R) OQOH QREC NQOH
The NEAT assembly process will translate the NEAT format
into the necessary absolute machine language.
It could be considered that all instructions in the basic 304
Command List are automatic built-in subroutines. There are a
number of operation codes that were designed specifically for
business data processing such as Edit, Merge, Move, Sift (or table
look-up), and Summarize that are powerful instructions and in
some cases are self-incrementing.
As an example, the Merge instruction will serve to illustrate
the nature of these business-type opera

tions. Specified in NEAT format would be the following mnemonic designators
and parameters: Designate first word, first item, each string Number of items in
each string Relative position of Major Key (if any), within item Relative
position of Minor Key within item Number of keys (1 or 2) for the Merge
Length of each item Specify three exits (Cutoff Merge only)
NEAT (National's Electronic Autocoding Technique) was in operation before
the first deliveries of the National 304 System. This system enables systematic
organization in the approach to a problem, an assembly compiler and a complete
library of generators, service programs, and subroutines. COBOL or COBOL-like
language will become part of the system in a reasonable time.
Each instruction may be relative to one of 10 Relative Index Registers. The
particular Index Register and the portions of the instruction which are to be
relative are specified within the instruction.

The unique 304 magnetic tape system is composed of sub-
systems of National 330 Controllers and National 332 Magnetic
Tape Handlers. The Central 304 Processor may handle up to
eight 330 Controllers, and each Controller may handle up to
eight Handlers to provide an upper limit of 64 Handlers available.
A record on magnetic tape may contain 10 or more words.
Multiple variable-length records may be written onto magnetic
tape with a single acceleration. The contents of one magnetic
tape may be read and simultaneously written onto another tape
unit until a desired record is reached. The copying may be spar-i
with computing, printing, input or output. Several copy
operations may be in progress simultaneously.
All conditions which may arise during magnetic file
operations are automatically detected and identified by the
Processor without programmed testing. Then a standard routine,
called STEP (Standard Tape Executive Program), will perform
all tape management
BRL 1961, NATIONAL 304, start page 0697

operations including: Repeat in case of error, write "Skip" record after proper
number of tries Repeat, or ,jump, on busy Handler or Controller Indicate
attempt to use locked-out tape Alternate Tape Units at end of tape Tape
identification, and label-checking Memory dump, and rescue points Log of
tape operations Executive control over sequencing from one program to the
next, or overlays
The time-sharing ability of magnetic tape copy allows for convenient file-
splitting, or multi-programming of different ,jobs where reference to the file is
for less than every record. Thus, completely independent programs can be
written and checked out, then tied together with the timing interlace being
performed by the equipment.
In order to improve the efficiency of Magnetic File Operations, any quantity
of numeric information may be packed from 6-bit code to 4-bit code with a
sin
gle instruction. Thus, utilization of tape storage, and transport speed, will
both be increased by 50'% for numeric information.
When the packed information is brought into memory, a single instruction
will reverse the transformation. Only that information requiring arithmetic
operation need be unpacked; sorting, table lookup, and all other logical
operations, can be performed
on packed information.

**CHECKING FEATURES**
FIXED
Processor
All transmission of data between the Processor and
peripheral units is checked for parity by character,
plus echo check for correct number of characters.
All transmission of data in and out of the magnetic
core memory is verified by a check character with
each word.
Magnetic File Operations
All recording on magnetic tape is immediately
checked by re-reading at a check head placed immedi-
ately behind the write head. Checks are made for
parity on each character, longitudinal parity check
over each record, character count on each record,
proper bounding of each record, and timing check.
These are separate, independent checks with any
conceivable out of the ordinary occurrence being
detected by at least 2 of these checks.
These same checks are in effect when reading and
while the tape to tape transfer (off-line copy is
in progress.
High Speed Paper Tape Reader
Duplicate photo-electric reading, duplicate trans-
lation, error halt on inadmissable characters, are
fixed checking features as well as automatic detec-
tion of paper tape slippage, undue drifting on stops,
and broken tape detection - distinguished from end
of tape.
High Speed Card Reader
The fixed checking features are duplicate photo-
electric reading and duplicate translation, error
halt on inadmissable characters, and also automatic
verification of clocking and column count, and de-
tection of out-of-registration or slippage.
High Speed Line Printer
Automatic check for non data characters, correct

number of characters, correct number printed, and each hammer
must fire one and only once per line. Continuous check on the
integrity of information stored in the printer buffer during
printing, each buffer position printed once and only once-also
each hammer. Continuous magnetic reading of special track on
print cylinder so that printer electronics "knows" the position of
the cylinder with answer-back to printer buffer verifying that the
print cylinder position at the moment each hammer is fired is the
same as the character stored in the corresponding buffer position.
There are two complete individual sets of circuits operating at
different voltages-one from buffer positions to activate
corresponding hammers and one activated by hammer action
back to buffer position. This answer-back verifies not only
correct character printed but also that the hammer was fired at
the precise instant to print the character clearly and with proper
alignment. The vertical format loop will halt the printer if it is
parted. Also, all control configurations (15 possible in the
vertical format loop must have even parity, continuously
checked.
High Speed Paper Tape Punch
Fixed checking features include echo check off punch dies
to verify actual character punched and detection of paper
tape exhausted or broken.
OPTIONAL
The Paper Tape Reader and Paper Tape Punch check for
character parity on codes that are checkable.
Certain peripheral units contain sequence-controlled circuitry to
test for proper operation and insure proper electronic functioning.

General requirements for physical environment include air
conditioning, humidity control, and provisions for maintenance
of equipment. There can be flexibility in construction as
pertains to the use of false flooring, ceilings, or conduits. It is
usually recommended that false flooring be used, as the area
under the false floor serves the dual purpose of protecting cables
and eliminates supply ducts for conditioned air. A false ceiling
eliminates the need for return ducts. The power specifications
call for 120208 volts, three-phase, four

Site preparation requirements Due to the physical structure of
the existing building, the location of the computer area within the
building, and the requirement for a separate airconditioning system,
the following additions and modifications were made at this site. A
30 ton airconditioning and air handling system was installed
composed of three ten ton chilled-water coolers and an air
handling system capable of moving 9,000 cubic feet of sir per
minute. This system provided for automatic temperature and
humidity controls geared to control the computer room to 40%
relative humidity. and 74oF temperature. The control system was
built around Johnson Controls with Bristol seven-day recording
devices. Air was delivered directly under the raised floor with
dampered registers around the periphery of the room to properly
distribute the incoming conditioned air. Return air was vented
through the ceiling in registers into an air plenum between the false
ceiling and the existing ceiling and returned to the air-conditioning
equipment. The raised floor was set ten inches above the concrete
slab. The false ceiling was installed eight and one-half feet above
the raised floor, and in the location selected was twenty inches
below the previously existing ceiling. A masonry wall was
contructed two feet inside the existing brick and masonry walls of
the building and supplemented by movable steel and glass partitions
where the room was divided away from exterior walls. The raised
floor is of cast aluminum in sections eighteen inches square with a
vinyl floor covering. Power and water were delivered to the
equipment room from existing central supply within the building
itself. The computer area itself has been equipped with Muzak
installation and an intercommunicating system utilizing the
existing speakers.

**PERSONNEL REQUIREMENTS**
Manufacturer
Since the National 304 System is a new system with the first
installation in November, 1959, at the present writing it is
difficult to determine normal personnel requirements. It is
anticipated that the advanced solid-state design and overall
system fabrication will result in most favorable operating
experience. The early performance of the initial systems has
borne this out.
It is expected that a typical 304 System can be maintained
by 3 or 4 engineer-technicians. Two and three shift operation
will require some increase.
Training made available by manufacturer to users includes
initial and turnover replacement training and executive
orientation. These are provided at no cost to the user at
mutually agreeable locations.

**RELIABILITY, OPERATING EXPERIENCE,**AND TIME AVAILABILITY Manufacturer Reliability and optimum operating experience were basic design objectives with the 304 System. The latest electronic developments and solid state devices have been used throughout. Design tolerances are set beyond those of"worst case" conditions of heat, voltage fluctuation and aging. Standardized plug-in cards are used throughout as well as etched circuit back panels to replace wiring harnesses and cables. Units are separately powered and contain circuitry which performs a sequence of automatic reliability tests to insure proper operation or to isolate for replacement of circuit cards. Individual units have extensive features to insure reliability as stated in Checking Features. The High Speed Paper Tape Reader and the High Speed Paper Tape Punch which can handle different codes by switch selection, have a programmable check on the proper code. A mode of the Test instruction can insure that the proper switch is set.

**ADDITIONAL FEATURES AND REMARKS**
Manufacturer
Outstanding features include a magnetic tape system which is
gapless, with timesharing of off-line tapeto-tape transfer (copy)
while searching. High InputsPaper Tape - 1800 cps. Punched cards
fed at 2000 cpm. Command structure is powerful for ease of
coding and debugging.
The 304 System has complete off-line conversion facilities -
for input and output transcribing. However, the input speeds of
1800 characters per second for paper tape and 2000 punched
cards per minute are so favorable that many businesses will find it
unnecessary to go through off-line input conversion. For
example, 30,000 transactions of 30 characters each would require
only eight and one-half minutes of processing time when reading
paper tape on-line. Transcribed transactions could be read from
magnetic tape by the Processor in about one half a minute. So the
off-line input conversion would not save more than eight minutes
a day.
An extensive library of programs were accomplished and ready
for use with the installation of the first 304 System. National's
Electronic Autocoding Technique --NEAT-- was developed to
reduce coding costs and to simplify programming. The purpose of
NEAT is to simplify the transition from flow chart to machine
code without losing any of the flexibility and power of the actual
304 instructions. It enables systematic organization to a problem.
Coding in NEAT can be thought of as the translation of a 304 flow
chart into pseudo instructions, employing mnemonic addressing.
The result of processing NEAT on a 304 computer, is a completed
machine code, which may be produced on magnetic tape, punched
cards, or punched paper tape. In the course of the computer run,
automatic code checking is done for obvious inconsistencies.
COBOL or COBOL-like language is being added to the NEAT
process. STEP, the program which takes advantage of the internal
logic to handle magnetic file housekeeping, is also in operation.
Other programs that are available are a Sort Generator, Librarian,
monitoring, tracing, and programs to facilitate program check-out.

protection from humidity, temperature, electrical, fire, or other
damage are the normal procedures and care that are customary
for mylar-magnetic tape.
U. S. Marine Corps, Camp Lejeune
Outstanding features include off-line copy operation for
simultaneous processing and read/write, maximum storage of data
per reel of tape, and high speed card reading.
Unique system advantages include ease of operation by means
of a console, which gives system control and components with a
minimum number of controls, a 320 Multipurpose Converter for
off-line operations, NEAT - a coding technique, which simplifies
programming, and a monitor feature which simplifies
codechecking.
Tape labelling is performed by means of STEP, (Standard
Tape Executive Program), which labels tape and checks
obsolescence of tapes before use.
U. S. Marine Corps, Camp Pendleton
Outstanding features are high speed card reader, high speed
printer, and transistorized solid state computer.
Unique system advantages are no inter record gap on
magnetic tape and a built-in business command structure.
Procedures have been adopted for magnetic tape labelling,
storage, shipping, and protection from humidity, temperature and
physical, electrical, fire, or other damage. Two labels are used;
one containing permanent identification, and the other
containing information of a temporary nature. Tape is stored in a
library which is temperature and humidity controlled. A semi-
automatic C02 system has been installed for fire protection. Afire
proof safe will be used to house Historical Tapes.
U.S. Marine Corps, Headquarters
Outstanding features include no inter-record gaps on tape.
This allows an effective read-write speed of 30 K per second,
and the ability to address any character or number of characters
of a word in storage.
Unique system advantages include transistorized
components, which bring about low power and air
conditioning requirements, and thereby reduces installation
costs.
Procedures have been adopted for magnetic tape labelling,
storage, shipping, and protection from himidity, temperature
and physical, electrical, fire, or other damage. Tapes are stored
in an air conditioned area. Shipment of tape is made in "netic"
containers. Any two of three installations can reconstruct
tapes of the third. Both outside labelling on reel and writing on
tape for positive identification of all records is performed.

**FUTURE PLANS**
Manufacturer
While retaining all of the previous features and specifications
of the initial 304, an improved model will be available starting in
the Fall of 1960. The Central Processor has been designated as
the 304-2, and will have MICRO-FLOW, Magnetic Character
Input, and allow multiple high speed line printing as output
MICRO-FLOW is a new mode of single-address operation that
essentially expands the instruction repertoire from 37 to 104
instructions. This new mode of operation does not in any way
supplant the powerful, business-type instructions. MICRO-FLAW
is designed for scientific computation, permitting fixed or floating
point arithmetic, and for areas of operation when the single-
address mode might be faster or more efficient. The single-address
MICRO-FLOW and the three-address business-type instructions
may be intermixed within a single program, switching from one to
the other to provide the most efficiency.
Magnetic Character Input can be provided with the use of the
304-2 Central Processor in conjunction with the National 402-1
Magnetic Character Sorter. Checks or documents encoded with
magnetic ink characters may be read at the rate of 750 documents
per minute. There will be input of the information into the
Processor memory, control over pocket selection, and ,jump table
control for unusual situations. The Magnetic Character Sorter can
be used off-line to sort documents as controlled by a panel on the
Sorter.
For high-volume output operations, the 304-2 Central Processor
will enable multiple printers on-line, up to four National 340 High
Speed Line Printers. Buffering and Busy Jumps will enable a
maximum of timesharing.
U.S. Marine Corps, Camp Pendleton It is proposed that the number of NCR 332 Magnetic Tape Handlers be increased from 5 to 8, that the NCR 304 Memory Size be increased from 2,400 to 4,800 words, i.e., 24,000 to 48,000 characters, and that the number of computer applications be increased from Personnel Accounting only, to that of Fiscal Accounting (including Disbursing functions) and local Supply Accounting.
American United Life Insurance Company Future plans
with regard to this system include the possibility, at the proper
time, of expanding the existing system to include additional
magnetic tape units, and perhaps another high speed printer.
Procedurally new applications will be added as desired. We are
looking forward to performing operations on research, market
analysis, and a more thorough analysis of sales and determining
standards of sales performance.

immediately by the machine operator with practically no lost
time. Sine installation of core memory, error free period is
close to 2 hours.
**ADDITIONAL FEATURES AND REMARKS**
Outstanding features include long worm length, high
arithmetic speeds, high tape speeds, checking features, CRT
printer, three address logic, and ease of programming.
Magnetic tape stored in computer room in metal cabinets.
Since the tape is not compatible with other units there is no
reason for it to leave the completely controlled climate of this
area. Acetate base tape is used.
Speed increased by taking short cuts in case of zero operands
and through the use of previous result as an operand. Provisions
for addition, subtraction, and shifting of instruction words make
possible programmed synthesis of instructions. A large variety of
conditional program transfer instructions are available. Three
address-modifier registers make possible the modification of
operand addresses without changing the stored instruction. Card-
tape-card conversion is used.

**APPLICATIONS**
The Borden Vote Tallying System is a special purpose electronic
system used to tally paper ballots at high speed. Votes are
accumulated by candidate and issue in a magnetic core memory,
and totals are output to a printer-punch unit. A short length of
punched paper tape is used to instruct the processor as to the
ballot width, color and format before ballots are read. This same
tape establishes the punch-out sequence. Two mechanical paper
handlers are attached to a processor. A ballot handler feeds
ballots in a fixed length of 24" and varying from 9" to 30" in
width at 10 ballots per second. Up to six ballot widths may be
individually selected by paper tape instruction without manual
intervention.
The ballots are not mechanically registered. The processor
contains the necessary skew interpolation circuitry to compensate
for a misaligned ballot. This circuitry is shared by the two ballot
handlers. Only one ballot handler feeds ballots at a time. While
one ballot handler is feeding and totals are being accumulated, the
second ballot handler is being reloaded with a spindled tray of
ballots and totals are being transmitted for the stack of ballots
previously read. The alternate use of the ballot handlers permits
the continuous processing of ballots. Each ballot is examined for
acceptability in accordance with the Election Code to accept only
valid votes. Overvoted offices and incorrectly voted recall issues
or recall candidates are not accepted,

but all valid votes are accepted to update totals. This analysis
and updating occurs prior to the reading of the next ballot.
**PROGRAMMING AND NUMERICAL SYSTEM**
Internal number system Binary and Binary Coded
Decimal
Digits per word 3 decimal, 4 binary, 1 parity
Digits/instruction one alpha per instruction
Instructions decoded 14 instructions
Arithmetic system Fixed point
Each operation is defined by an alpha instruction
character.
Number range 000 to 999 for each of 540 totals
One alphabetic character defines an instruction operation. For
example, one character, followed by appropriate designators,
instructs system on specific locations of voting squares on the
ballots to be read. Another alphabetic character initiates the
actual reading of ballots- Instructions are read from punched paper
tape and are executed in sequence as read from the tape.
Essentially all operations in the system are builtin subroutines.
These include updating of the totals in memory as each ballot is
read, checks on overvoting, punch-out of candidate totals, etc.
All programming is in direct instructions.
Registers include instruction register, memory in-out register,
ballot mark input registers, and punch encode register.
**ARITHMETIC UNIT**
Add time is 33 microseconds, including storage
access, 6.6 for the actual add operation only.
Arithmetic operation of updating totals after read-
ing each ballot is an automatic subroutine.

One system, employing two ballot handlers, requires
approximately 1,200 sq ft of floor area. Total installation load
for system is approximately 15,000 pounds. Data processor
weighs approximately 2,000 pounds; each ballot handler, about
5,200 pounds. Operator consoles and output printerpunches
account for remainder. Floor should be capable of supporting
distributed load of 300 pounds square foot. Site preparation
requirements for each system include air compressor, an air fan
to provide high-volume low-vacuum air, and a vacuum pump for
high-vacuum pressure.
Ballot handlers operate alternately in reading ballots. While
reading, drive motors in ballot handler draw approximately 20
KVA from 220-Volt 3 phase line. Air compressor, low-
vacuum fan, and high-vacuum pump, required for each system,
draw about another 20 KVA per full system from 220-Volt 3
phase line.

Operation tends toward open shop.
Equipment operation is relatively simple. Initial personnel are
trained on the ,job by manufacturer. Additional personnel can be
quickly trained on the ,job as required.
The Numericord Director is a special purpose digital computer
and although it is sometimes programmed manually, programs
are normally prepared by a large general purpose computer.
When used in this fashion the Numericord system can usefully be
described as a piece of special purpose off-line peripheral
equipment used in conjunction with a number of large general
purpose computers.
Normal personnel requirements for the system usually consist of
a trained operator and a trained electronic technician who is on
call but not necessarily present at the equipment at all times.
Programming is done by the regular data processing department
mathematical programming section.
**ADDITIONAL FEATURES AND REMARKS**
Purpose - provides fully automatic control of complete
work cycles for general-purpose machine tools having as many
as five simultaneous axes of movement.
Operation - places all machine movements and auxiliary
functions under control of a magnetic tape program which is
prepared electronically from numerical data off part drawings.
Significance - provides a "store" of skills which makes
workpiece accuracy a function of engineering and methods
planning completely independent of machine operator's
experience.
Application - while capable of automatically operating any
type of machine tool, optimum effectiveness is achieved on
multiple-axis, three-dimensional contouring machines.
Machine Scope - controls standard machine movements to
generate such geometric shapes as straight lines, circles, ellipses
and spirals or any shape that can be mathematically defined or
arbitrarily set up in three-dimension coordinates.
Accuracy - tolerances obtainable with the Numericord
System of machine control range from � .0005" to � .001" on
the largest and most intricate workpiece. No cumulative error.
**FUTURE PLANS**
For several years this system has been used primarily by the
aircraft and missile industries. Modifications and adaptations of
the system are now being designed for special applications in
precision plane and contour map making, coordinatography,
precision plotting, flame cutting, X-ray inspection, and riveting.
