ADDITIONAL FEATURES AND REMARKS
Manufacturer
The IBM 604 Electronic Calculator is a general purpose electronic
digital computing machine which is helping solve problems in science,
engineering, business and government.
Reading problem data from IBM punched cards at a constant speed of 100
problems (cards) a minute, it can go through as many as 60 separate steps,
such as multiplications and divisions, to obtain the solution to a single
problem.
Answers are recorded in the same cards which carry the problem data, or they
can be punched in specially designated cards.
The smaller of the two cabinets is the electrical card reading and punching
unit. The larger cabinet is the all-electronic unit which includes the
following
sections: power, timing, arithmetic, storage and switching.
Many built-in features make this electronic calculator easy to operate and
service. These include interchangeable control panels for changing from one
type of operation to another, and testing devices and pluggable
subassemblies
which facilitate rapid maintenance and service.
These machines have been produced on the assenbly line at IBM's plant in
Poughkeepsie, New York, since early 1949.
Bankers Life Double punch, blank column detection on the 521.
FUTURE PLANS
WSMR Proposal for Univac Solid State "80" forwarded
through command channels. LA County
Should be able to shift to IBM 1401 (punched card configuration) for
costing, utilities, etc. in about 18 months.
Acquisition of an IBM 1620 (with hookup to 1401) would permit complex
high speed calculations for engineering - such as traversing, earthworks,
calculations (cut and fill), least squares adjustments, etc.
Contemplate use of aperture film cards for maps.

BRL 1961, IBM 604, start page 0335

Could then have a complete set of maps in each reg-
ional office (surveyor's maps - street no. maps -
special district maps - architectural drawings -
storm drain maps, etc.)

ADDITIONAL FEATURES AND REMARKS
Manufacturer
The IBM 607 Electronic Calculator is designed for use by
business and industry. Because of its expanded capacity, the
overwhelming majority of business calculations requiring
multiple machine operations are performed and checked in a
single operation. It is capable of performing and checking
14,000 computing operations a minute.
The memory capacity of the 607 makes it possible
to use intermediate calculated results as well as
original data in solving a problem. Other necessary
information not punched in cards, such as tax per-
centages, discount rates, and overtime factors, may
be entered as required.
Rossford
It is possible to use intermediate calculated results
as well as original data in solving problems.
US NOTS
A unique system advantage is its availability for
static test data reduction. It should be noted that
this computer (IBM 607) is located 5 miles distant
from the Station's IBM 709 system.
FUTURE PLANS
US NOTS Proposal for 1401 System to replace present
system. Proposal for micro-wave hook-up with IBM 709 and
Polaris test stand-digital data processor (to write 709 binary
tape).

ADDITIONAL FEATURES AND REMARKS
Manufacturer
IBM's "608", the first completely transistorized calculator for commercial
applications, operates without the use of a single vacuum tube.
Transistors-tiny germanium devices that perform many of the functions of
conventional vacuum tubesmake possible a 50% reduction in computer-unit
size and a 90% reduction in power requirements over a comparable IBM tube-
model machine. They are mounted, along with related circuitry, on banks of
printed wiring panels in the 608.
The machine's internal storage, or "memory", is made up of magnetic cores-
minute, doughnut-shaped objects that can "remember" information
indefinitely,
and recall it for use in calculations in a few millionth of a second.
For IBM, the 608 marks the achievement of production techniques for the
manufacture, on a large scale basis, of computing and data processing
equipment
combining transistors, printed circuits and other forms of miniaturization.

1,200-card-capacity hopper face down, 12-edge first. The cards
feed continuously from one station to the next at the rate of 200
cards per minute. Thus, while one card is being read for
calculation, another is being punched, and a third card may be
read for checking, gang punching, etc., or for recalculation. Input
and output (double-punched blank-column) are checked.

The ratio of input time to computing time for most
statistical problems of any complexity is less than
one. The ratio of output time to computing time for
most statistical and engineering problems is small
except for large problems where intricate programming
requires temporary storage of large quantities of
data on the data tape. Small internal storage makes
programming of large problems intricate.

USNAD Outstanding features include auto-point (floating point)
calculations, good reliability, and ease of programming.
TVA Since this computer is used by a relatively small integrated
group, tape storage is no problem. Each operator takes care of his own
special tapes, while standard tapes axe labelled and filed close to the

programming, and programming in engineering language.
Lockheed Electronics Outstanding features include computes and
prints-out in floating point point notation, very fast and easy to program,
and
air conditioning not required. Duration time of arithmetic operation too
long
especially those for trigonometric function, i.e., multiply 0.78 sec.,
square root -

Carleton Outstanding features are ease of programming (simple
command structure) and use as desk computer.
U of Louisville Unique system advantages are automatic positioning
of decimal point and simplicity in coding.

FUTURE PLANS
USA TRC It is proposed that the system be replaced by an IBM
1620.
USNAD The rental of the IBM 1620 Digital Computing System has been
approved by the Bureau of Naval Weapons. The IBM 1620 has much faster input
and computing times (input of 180 char/sec and access time of 20 microsec).
In
addition the 1620 has core storage of 20,000 digits with variable word len
h. The
rental of the IBM 1620 will be approximately $1,600 per month.
TVA The workload is increasing rapidly and may require some change in the
future. Present plans are indefinite.
DuPont To date, primary usage of the IBM 610 has been in the
development and research areas for engineering calculations and evaluation
and
analysis of experimental data. Continued use in this field is anticipated.
More
complex applications in the statistical field will be pursued in the plant
process
and product areas. Increased activity in the production and cost accounting
department is expected. At this time, no plans for an expansion or
modification of
the present computer system has been made. However, the adequacy of the
present
system for current and future demands will be studied within the next six
months.
Results and recommendations of this study will determine the need for
expansion
or acquisition of a new system.
Lockheed Electronics IBM 610 to be
replaced by IBM 1620.
Worcester Poly Eventual acquisition of some other computer as addition to
or replacement for present one, possibly to meet administrative as well as
educational
and research needs.

APPLICATIONS
The IBM 632 is designed primarily for invoicing. It is available in
four models, including models with card punch, printing card
punch, and punched paper tape output. The 632 combines
calculating and typing in one unit. It automatically adds, subtracts,
and multiplies the information keyed into the companion
keyboard. It also automatically inserts decimal points, computes
taxes, discounts and accumulates information for daily totals. The
accuracy of electronics and magnetic core "memory" give the
IBM 632 Electronic Typing Calculator the ability to handle a
variety of business applications. This model, incorporating
punched card output, punches desired information into IBM
punched cards simultaneously with the typing action. The cards
may then be further processed in an accounting system.
