INTRODUCTION
Successful installation of a650 System requires considerable planning. Physical
installation planning should start at least twelve months before a650 System with
magnetic tapes and/or disk storage is scheduled for delivery. Six months of
advance planning- is usually adequate for a650 System with punched card input-
output and storage unit.
This physical planning manual should be carefully studied and consideration given
to the following items and their requirements:
1.Sufficient and suitable floor space
2. Floor loading
3. Power source
4. Air conditioning
5.Temperature and humidity controls
6. Customer Engineering service area
7. Tape storage
8.Unit arrangement for efficient customer operation

GENERAL DESCRIPTION
A650 Data Processing System is made up of acombination of several units
connected by cables
.
A650 Basic System must have:
650 Console Unit 1only
655 Power Unit 1only
These units may be installed:
407 Accounting Machine
533 Card Read Punch
537 Card Read Punch
653 Storage Unit 1only
A650 System with magnetic tapes and/or disk storage must have:
650 Console Unit 1only

and/or
355 Disk Storage 1to 4
These units may be installed:
407 Accounting Machine
533 Card Read Punch
537 Card Read Punch
838 Inquiry Station
The 650 Console Unit has acontrol console and contains the magnetic drum and
the logical and arithmetic circuits .
The 652 Control Unit has an indicating panel and contains the power supply and
control circuits for the 727 and/or the 355 and 838 units.
The 653 Storage Unit has an indicating panel and may contain immediate access
storage, index registers and automatic floating- decimal arithmetic. This unit
with immediate access storage is anecessary component of atape system, and/or
disk storage system.

The 655 Power Unit contains the power supplies for the 650, 533's and 537 Tsin
addition to input-output translating circuits
.
The 727 Magnetic Tape Units contain the tape feeding mechanism and the reading
and writing mechanisms
.
The 355 Disk Storage provides alarge capacity storage of data with random
access. The unit contains the disks, access arms and control mechanism. There
are side windows in the 355 units for viewing the mechanisms, but it is unnecessary
for the operator to see these windows from the 650 Console unit..
The 407 Accounting Machine is an input-output unit. It has components for reading
data from cards, storage of data, transmitting data to the 650, printing data
stored from cards or received from the 650
.
The 533 Card Read Punch is acard input- output unit. It has two independently
operated feeds, one for reading data from cards to the 650 and one for punching
data into cards from the 650
.
The 537 Card Read Punch is acard input-output unit. It has one card feed, where
data can be read from cards to the 650 and data punched into cards from the 650
.
The 838 Inquiry Station is amodified IBM Electric Typewriter, stand, and
appropriate control circuits, that permit the operator to obtain arecord from
the disk storage or insert limited data into the disk storage.
Access to the various units by customer personnel will vary with the type of
application. However, only occasional reference to the 652, 653 and 355 is
required.

SPACE AND LAYOUT REQUIREMENTS
Space and layout requirements will differ for each 650 System installation
.
The following are general rules for guidance:
Space
The floor area required will be determined by the number of units in the system,
length to width ratio of the room, location and size of columns and provision for
future expansion.
Atypical 650 Basic System requires 250 to 600 square feet of floor area.
Atypical 650 System with magnetic tapes and/or disk storage requires 1000 to
1800 square feet of floor area, including tape storage and Customer Engineering
service area. The Customer Engineering service area may be 50 or 150 square
feet as described later in the manual
.
Layout of Machine Units
When laying out the machine room area for specific unit locations, consideration
must be given to the size of the various units, the clearances required for opening
of gates, the lengths of connecting cables and location of units for efficient
operation. To make alayout, it is necessary to have an accurate drawing of the
proposed 650 area scaled at 3/8 inch equals 1foot. Plastic templates of the
various units may be obtained from IBM. The templates are to the scale 3/8 inch
equals 1foot and show the allowable minimum working clearances
.
For a650 Basic System the customer and salesman should make a3/8 inch
scale layout of the machines .Cables required to connect the machines will be
sent by the factory. Unless otherwise specified to the factory, 17 foot cables
will be supplied with the first punched card input-output unit, 22 foot cables with
the second and 31 foot cables with the third.
For a650 System with magnetic tapes and/or disk storage, a3/8 inch scale layout
should be made by the customer and salesman, with the advice and assistance of
the Physical Planning Engineer. Each IBM branch office is responsible for ordering
the correct external cables .The cable order should be made up at the branch
office and forwarded by the Branch Manager to the Physical Planning Engineer
for formal approval and processing.
On pages 42 to 47 are several possible layouts. Other arrangements may be
made by using the connecting cable lengths, unit dimensions, and clearances
shown on pages 32, 33 and 35.
11

FLOOR CONSTRUCTION
The machine room floor must support the total weight of all the components as
well as the localized weight at each machine caster. The floor must be capable
of carrying aload of approximately 100 pounds per square foot.
The various units of a650 System with magnetic tape and/or disk storage are
connected by alarge number of cables .With this system it is recommended
that cables be laid beneath the machine floor.
The most common method of preparing afloor for a650 System is to construct
araised floor over the building floor. Aproperly designed raised floor distributes
the entire machine load more evenly over the building floor and structural
members, materially reducing the necessary pounds per square foot rating
required of the building floor, and can provide ameans of having connecting
cables under the floor.
The raised floor can be constructed of wood, concrete, steel, or aluminum,
depending on the customer's desires, budget, local building codes and fire
insurance requirements
.
The covering used will depend upon such factors as mobility of machine units,
appearance and cost. Among the better types are rubber tile, vinyl tile, grease
-
resistant asphalt tile and finished hardwood floor. The type of floor covering
used should not dust or chip and should lend itself to ease of cleaning.
There are two basic types of raised floor construction in general use, "Raceway
Floors" and "Free Access Floors." These two types of floors are illustrated
on pages 40 and 41
.
Araceway floor has raceways or troughs 14 inches to 16 inches wide and 6inches
to 8inches deep built into the raised floor. The raceways are normally run
parallel to the walls of the room and carry the connecting cables. Sometimes,
they are also used to carry the 208 or 230 volt power supply cables and
connections .Raceways should be covered with removable covers, so the cables
are accessible and may be easily laid in the raceway. Raceways may also be
provided in existing floors
.
Afree access floor is so designed that cables may run in any direction under
the machine floor without being restricted to definite paths. The floor panels
should be removable. This type of floor allows for more flexibility in machine
layout with the fixed lengths of cables supplied with the 650 System .In addition,
changes in machine location can be made with aminimum amount of construction
work, even where raceways are required beneath the free access floor.
12

If cables are left on top of the floor, the cables must be covered by aramp to
prevent damage to the cables from traffic over them. The ramp is provided
by the customer. Figure 1, page 39, illustrates the design and dimensions of
such aramp.

AREA CLEANLINESS
The operation of 650 tape installations has shown that dirt and dust can be major
sources of trouble if not properly controlled.
The following will acquaint you with facts concerning building materials and
room maintenance:
A. Materials
1.Asphalt tile is not as satisfactory for 650 installations as vinyl or
rubber tile, because it is more brittle and there is agreater tendency
to chip at the edges and to crack
.
2. "Marbleized" tile patterns have been found to be difficult to keep clean
because dirt cannot be distinguished from the pattern.
3. Carpeting may be used but alint free and static free material should
be used. This also applies to drapes used for soundproofing or
decorative purposes
.
4. Ceiling and wall material finishes should not "dust" or flake.
B.Cleaning
1. Waxing, when necessary, should be kept to aminimum. Some waxes
tend to flake and this can seriously jeopardize the operating efficiency
of the installations from adust standpoint. The method of application
of wax should be such that wax is applied only on intended surfaces
.
2. Cleaning should be done with adamp mop, never dry or wet. Under
no circumstances can sweeping be tolerated.
3.Vacuuming has been found effective, if an external vacuum or an adequate
sealed or filtered container, (i.e. water-type tank), is used.
4. It is recommended that smoking be permitted only in the immediate
vicinity of the console. Under no circumstances should smoking be
permitted while handling tape, when attending tape drives or in the
tape storage area .Tobacco ashes on the tape can cause errors
.
5.Material should not be placed on top of machines .In addition to
restricting the air flow, foreign material may fall into the machines
.
Tape reels and machine covers, similarly, should not be laid on the
floor or on the machines
.
14

6.When vacuuming under machines, it is recommended that anonconductor
type of nozzle be used to minimize the possibility of an electrical
accident
.
7. Before installing the machine, it is imperative that all exposable under-
floor areas including cable raceways be thoroughly cleaned. It is also
absolutely necessary that the regular cleaning schedule include periodic
cleaning of these areas
.
8. It is not possible to recommend acleaning schedule. Since each
installation will differ, experience will have to dictate, but aschedule
should be planned which will include cleaning the entire installation
at least once aday
.

AIR CONDITIONING REQUIREMENTS
A. Basic System
The air in the machine room must be maintained within the following limits:
1.Temperature between 50° and 90°F
.
2.Relative Humidity between and 80%
.
B.Tape System
The air in the machine room must be maintained within the following limits:
Acetate Tape
1.Temperature between 65° and 80° F
.
2.Relative humidity between 40 and 60%
.
Mylar* Tape
1.Temperature between 50° and 90° F
.
2.Relative humidity between 20 and
C.Disk Storage System
The air in the machine room must be maintained within the following limits:
1.Temperature between 50° and 90° F.
2. Relative humidity between and 80%.
D. Tape and Disk Storage System
The air in the machine room must be maintained within the limits specified
for the type of tape to be used.
E. Air Filtration
Normal air filtration is adequate for most installations .Air filters should have
an efficiency rating of 20% by the National Bureau of Standards Discoloration
Test Method.
Special air filtration is necessary in only those installations which will be
subject to corrosive gases, salt air or unusual dirt or dust conditions
.

16

The above limitations of Mylar tape and air filtration are applicable to 650
installations which include tape and/or disk storage only, and in no way apply
to the 700 series equipment which may be used as peripheral equipment in
the 650 installation. This peripheral equipment includes the Tape Data
Selector, Tape-to-Card, Tape-to -Printer and Card-to-Tape systems, all
of which require the temperature, humidity and air filtration specifications
as outlined in the appropriate physical planning manual
.
If the 650 is subjected to temperature below 50° F.for any extended time,
it will be necessary to provide an appropriate warm-up period before
starting the machine, to prevent damage to the magnetic drum
.
During nonoperational periods, when machine power is "OFF, "the room
air temperature may be as high as 110° F. However, the room temperature
must be brought below the maximum temperature specified for the system
before the 650 System is started.
Heat dissipation data is located on pages 30 and 31
,

TAPE STORAGE
Short Term Storage
When tape is stored for short periods of time, the surrounding atmosphere
should be controlled with the following limits:
Acetate Tape
1.Relative humidity 40 -60%
2. Temperature 65 -80° F.
Mylar Tape
1.Relative humidity 20 -80%
2.Temperature 50 -90° F
.
If the tape must be removed from this conditioned atmosphere, it should be
hermetically sealed in aplastic bag.
If the container is not hermetically sealed, the tape should not be used until it
has been returned to the conditioned area for alength of time equal to the time
it was removed. Tapes removed from the conditioned area for periods exceeding
twenty-four hours will require only twenty-four hours of conditioning.
Long Term Storage
A.The reels should have proper mechanical support as provided by the
dustproof containers
.
B.The reel and container should be enclosed in ahermetically sealed
moistureproof plastic bag.
C.Storage should be in an area where the temperature range is between 40°
and 120° F.
D. The tape should not be subjected to strong magnetic fields, or be in contact
with magnetic materials. Either of these can cause loss of information or
the introduction of noise
.

TEMPERATURE AND HUMIDITY RECORDING INSTRUMENTS
It is recommended that all customers install temperature and humidity-
recording instruments. Recording instruments are necessary to provide a
continuous record of temperature and humidity conditions in the machine area
.
Also, if the air conditioning requirements are not met, arecord is available
to indicate the extent and duration of the undesirable condition.
The record of temperature and humidity can be used:
A. To assure the customer that his air conditioning installation is continuously
performing its job properly. Installation errors and loss of efficiency due
to malfunction of some part of the system can be quicldy detected.
B.To determine if amandatory drying- out period is necessary when humidity
limitations are exceeded. The drying-out may be necessary if the excess
humidity occurs either during periods of actual machine operation or during
periods when the machine is shut down and unattended .The extent and
duration of the excess humidity is used to determine the duration of the
drying- out period.
C.To determine if the air environment in the machine area meets the
requirements for the machine
.
Experience gained from machines already installed has proved that the purchase
and installation costs of the recording instruments are awise investment for
the customer. The instruments warn of approaching air conditioning trouble so
that corrective measures may be taken to prevent machine shutdown and its
associated effects.
The instruments should be of adirect- reading, electric -drive type with a7day
recording chart. The instruments should be so located that they will indicate
the conditions of the air entering the machines
.
Avisual or audible signal device should be incorporated into the instrument
installation. Its purpose is to provide avisual or audible indication that the
temperature or humidity conditions in the 650 area are nearing the maximum
limitations stated in this manual. Action can then be taken by the customer's
personnel to correct the situation and avoid interruption of machine operation.
