New EAI computer puts the advantages of analog computation right
at your desk. Accurate up to 0.1%, it is capable of performing the
mathematical operations of summation, integration, sign changing,
multiplication, division, and function generation; those operations
required in the solution of most of your routine engineering prob-
lems. Differential equations, basic to most engineering problems,
ean now be solved with surprising rapidity. Even if you have never
seen a computer before, you can learn to operate the TR-10 as easily
as you learned to use a slide rule.
You simply turn a knob to feed in design parameters. The com-
puter provides an instant-by-instant dynamic picture of the effect of
each change. You can study the relationships of heat, pressure, flow,
vibration, torque or any other variable. And you can visually com-
pare one with the other. This new insight into the behavior of dif-
ferential equations helps you to arrive at solutions faster ... easier.

You can experiment with new ideas that formerly were too
costly or time consuming to try. You can perfect your design and
work out all the “bugs” right on the computer... before building
pilots or protoypes. It can drastically reduce design time and costs.
Companies who already have large analog computer installations
will find the PACE TR-10 can be used to solve smaller problems and
eliminate tie-ups and excessive waiting time for large equipment. It
is ideal for breaking-in new engineers to the advantages and tech-
niques of analog computation.

TYPICAL USES OF HIGH SPEED REP OP
Users of the. PACE TR-10 Analog Computer
will find the High Speed Repetitive Operation
Accessory a valuable aid to the solution of a
variety of computing problems. The high prob-
lem solution rates possible with the repetitively
operated TR-10 makes it possible to almost in-
stantaneously view the effect of varying the
parameters of a problem. This unique ability
provides a powerful and economical computa-
tional tool for solving those problems requiring
multiple solutions of the problem equations.
Typical problem areas are:
System Optimization ,..the selection of para-
meter values which give the best overall per-
formance.
Boundary Value Problems ...the solution of dif-
ferential equations in which the problem is to
find the initial conditions for specified solutions
of the equation.
Model Building ...the problem of determining
a mathematical representation for a system of
known response.
OTHER USES of High Speed Repetitive Opera-
tion...rapid exploratory studies to conserve
computing time...rapid approximation of op-
timum system parameters and determination
of stability regions of control systems... ap-
proximate computation and display of integral
transforms, such as Fourier integrals, super-
position integrals, and correlation functions...
statistical studies requiring many solutions...
plus a wide variety of routine computational
problems requiring numerous solutions.
The High Speed Repetitive Operation Accessory
permits the PACE TR-10 to be operated alternately as
a real time or high speed repetitive computing device...
utilizes the wide bandwidth of the TR-10 Computing
Components... with no loss in real time computing ac-
curacy, changing the computer operation from real
time to high speed repetitive operation is accomplished
by a single control... without any reprogramming or
repatching of the problem.
These outstanding features of the Type 2.246
Accessory Group add to the problem solving capabilities
of the TR-10 Computer.
® Selection of real time or repetitive operation of the
computer by a single control... requires no repatch-
ing or reprogramming... allows immediate, perma-
nent recording of selected solutions.
* Computing times of from 20 to 500 milliseconds per
solution.
* Switched control of solution times at fixed values of
20, 50, 100, and 200 milliseconds per solution.
® Continuous control of solution times between fixed
values... by as much as 2.5 times the fixed value.
e All solid state timing unit.
* Precision polystyrene feedback capacitors.
¢ SLAVE feature for control of two repetitively oper-
ated TR-10 Computers from either computer.
In REPETITIVE OPERATION the computer is
continuously recycled between the RESET and
COMPUTE mode of operation. The problem is,
therefore, solved over and over at some predeter-
mined repetition rate, usually often enough to
allow its presentation on an oscilloscope.

Dual Integrator Networks (Type 12.263)
The Standard Basic TR-10 is capable of
solving up to two second-order differential
equations plus associated linear algebraic
operations.
The component complement of the TR-10 is limited only by the number of components kept on hand. The use of
* standardized, plug-in, solid-state computing components together with a unique design concept allows considerable
flexibility in selecting the complement of non-linear comvuting components, All components plug into the computer
console from the front of the computer ...the computer patch panel .is automatically formed by the color coded
patching modul forming the front of each component. This feature, coupled with the ability to place different
types of computing components into the same console position, permits a flexibility in arranging different equipment
complements, both initially and for later expansion.
That portion of the TR-10 Computer Console which ac-
cepts plug-in computing components is divided into
four areas:
ATTENUATOR ROW — This is the top row of com-
puting components. It has been wired to accept and
has positions to accommodate up to a maximum of
10 Dual Coefficient Setting Potentiometer plug-in
modules 120 poteniometers).
NON-LINEAR ROW — This is the middle row of com-
puting components. It is wired to accept a variety
of interchangeable linear and non-linear computing
components.
AMPLIFIER ROW — This is the bottom row of com-
puting components. It is wired to accept and has
positions to accommodate up to a maximum of 10
Dual Operational Amplifier Modules ‘20 amplifiers).
CONTROL PANEL — This is the area on the right side
of the Control Panel. Three (3) positions are avail-
able ‘numbered left to right) to accept the follow-
ing accessory equipment:
POSITION CPI — High Speed Repetitive Operation
Control Panel.
POSITION CP2 — Type 20.366 Function Switch
Assembly.
POSITION CP3 — Type 42.185 Quad Coefficient
Setting Potentiometer Assembly.
Non-linear computing components ‘Multipliers, DFG'S,
etc.) are housed in full-width (1% inches) or half-width
‘34 inches, plug-in modules that are interchangeable in
the NON-LINEAR ROW. This row consists ot twenty
34 inch positions numbered to correspond to the num-
bering strip across the top of the row. It has the
capacity for mounting twenty (20) half-width modules
or ten (10) full-width modules or any combination of
both which does not exceed the total capacity o: the
row. Full-width modules occupy two adjacent odd and
even numbered -position pairs, i.e., =l ana =2, =5 and
=6, etc.
The NON-LINEAR ROW makes provisions for the following inter-changeable
components in any combination providing that the total capacity of the row is not
exceeded.
INTEGRATOR NETWORKS. Up to nine (9) Type 12.263 or Type 12.245 Dual Net-
works can be accommodated in positions +1 through +18, Each dual network occu-
pies adjacent position pairs as for example positions +1 and +2, +5 and <6 ,etc.
MULTIPLIERS. Up to nine (9) Type 7.045 Quarter Square Multipliers can be
accommodated in positions =1 through +18. Since the multiplier is housed in a
full-width module it also occupies aajacen position pairs.
VARIABLE DFG. Any of the three available models of the VARIAGLE DFG;
Type 16.154, Type 16.155, or Type 16.165, can be accommodated in any even
numbered position with the exception of position =20.
X“ DFG. The Type 16.101 function generator can be mounted in any even num-
bered position with the exception of position =20.
LOG DFG. Any of the two available models of the LOG DFG; Type 16.126 or
Type 16.133, can be positioned in any even numbered position with the exception
of position +20.
REFERENCE PANEL. The Type 12.266 REFERENCE PANEL can be positioned in
ony even numbered position with the exception of position +20.
DUAL TIE POINT PANEL, This unit can be positioned in any position in the
NON-LINEAR ROW.
CO ee ae The Type 6.143 COMPARATOR may be positioned in position
+18 only.
FUNCTION SWITCH PATCHING MODULE. The Type 12.264 Patching Module
may be mounted in position +19 only.
QUAD POTENTIOMETER PATCHING MODULE. The Type 12.265 Patching Module
may be mounted in position +20 only.
NOTE: The above assignment of computing components applies to the standard
TR-10 Console. Special computers may be supplied with provisions for
mounting DFG’s or REFERENCE PANEL in the odd numbered positions
(with the exception of position +1) or for accommodating more than one
COMPARATOR,
system design of PACE tR-10 allows unlimited computing flexibility...

PACE TRAO versatility allows one computer to do the work of -
or two TR-10's can be slaved together to solve larger problems
With the TR-10 you need never worry about your prob-
lems becoming too complex. From the standpoint of
problem solving capabilities the TR-10, is in many re-
spects, a combination of several computers. If your
problem is too large or complex for the STANDARD
BASIC TR-10 you simply expand the computer by
plugging in the needed computing components. Prob-
lems requiring an extra integrator or multiplier need
no longer go unsolved. You simply remove an un-
needed component from the expanded computer and
replace it with the proper computing component. If
your problem becomes too large for a single expanded
TR-10 then you slave two TR-10’s together. With the
TR-10 Computer you are not limited to fixed equip-
ment complements...the combination of computing
components is easily changed to satisfy your problem
requirements.
STANDARD BASIC TR-10... provides an economical
desk-top analog computer which is ideal for instruc-
tional purposes or for the solution of less complex
problems.
STANDARD BASIC TR-10 plus specific components
...allows you to solve those “smaller” physical prob-
lems which are complicated by the presence of non-
linearities.
STANDARD NON-LINEAR EXPANDED TR-10...
provides a desk-top analog computer with sufficient
computing components to solve several complex equa-
tions simultaneously. Allows you to make a more de-
tailed analysis of your design problem.
STANDARD NON-LINEAR EXPANDED TR-10 plus
spare non-linear components ...effectively provides
several computers in one TR-10 Console. By purchas-
ing additional non-linear components beyond the con-
sole non-linear capacity you can achieve unusual
computing flexibility.
SLAVING TWO TR-10 COMPUTERS ... provides an
analog computer with sufficient capacity to solve com-
plete system problems in some detail. With the TR-10
SLAVE feature you have complete control of your
problem solution... from either computer. TR-10
Computers are easily SLAVED...or disconnected to
permit the solution of two individual problems simul-
taneously.
Experience has shown that the complement of comput-
ing components provided in the Standard Non-Linear
Expanded TR-10 will satisfy the computing require-
ments of typical engineering design problems. This
