Introduction

The analog-computer program of AEG-TELEFUNKEN comprises a range of machines that, from the simplest, price-advantageous desk computer up to the advanced precision analog computer, can meet every user requirement, particularly in the area of hybrid precision-analog-computer technology.

The desk computers RA 710 and RA 742 represent an interesting contribution, in that they serve as flexible precision instruments for solving ordinary differential equations and simulating dynamic processes, and they are furnished with a feature set corresponding to the latest state of development for precision analog computers.

The desk computers RA 710 and RA 742 are suitable for use in conjunction with the following accessory units:

• the Digital Attachment DEX 100 (or DEX 102) for the combination of numerical and iterative computing; this expands the desk computer into a solution instrument for hybrid problems.
• the Non-linear Networks MNT 740 for extending the analysis of non-linear differential equations.
• the Electronic Resolver ERS 801 for coordinate transformation.
• the Electronic Output Device LZS 100.

All accessory units can be combined with the RA 710 and RA 742 and with one another as desired. The resulting system can thereby be adapted to given problem requirements and expanded step by step.

• Simulation or digital re-computation of partially known processes

The RA 710 is suitable for the following task ranges:

• For tasks involving up to two Rechenwerte (computed quantities), direct analog output can be read; larger problems are solved in conjunction with an oscilloscope or the digital attachment DEX.

• Convenient function entry via single-element switching
• Automatic operation control through interchangeable patchboard

Computing Elements

The 8 computing amplifiers allocated to the desk computer can be used as adders, summers, or integrators. Up to 30 parallel computing runs can be initiated. Summers or integrators can be used simultaneously; and two compute amplifiers can be interconnected, so each can operate alternately as an adder and as an integrator.

For each of the two types of function, the following function panels are provided:

Networks for 5 fixed functions:

Function	Count
Quadratic functions: Y = X²	(4)
Cubic functions: Y = X³ or -X³	(2)
Cross-multiplication: Y = 2·XY or 1/4·XY	(2)
Sinus-simulation: Y = sin X	(2)
and

Networks for 5 variable functions:

Function	Count
Networks for 5 variable functions with up to 5 break points each	(1)

For each of the 8 selectable variable functions, up to 5 break points are provided (settable mechanically or electronically).

• Two patchboard networks | (6)
• Two coefficient potentiometers (mechanically settable) | (6)
• Readout potentiometer | (1)
• Automatic operation control through patchboard

For further computational applications, two zero-point quantities are available.

Patchboard

The 8 computing amplifiers are connected such that at each input and output of each amplifier the connection assignment and any connections made via coefficient potentiometers can be altered. Furthermore, the two function panels can also be connected to the individual amplifiers through the patchboard.

All computing elements of the desk computer are connectable via the patchboard; the connections from input and output to the problem amplifiers as well as the connections via the function panels can be preset before the actual computing run and then activated all at once by the patchboard.

Controls

The built-in controls on the desk computer illuminate the computing elements on the patchboard. They can be switched together as “Reset” and “Halt.” With external control and timing it is possible to connect either the Digital Attachment or other external equipment from which automatic operation switching is to be initiated.

Mode “Einzel Rechnen” (Single Run)

By pressing the “Einzel Rechnen” button the computing run is started for a set time, e.g., for a continuously variable automaticrun duration of 1 to 10 seconds or for any desired longer duration depending on the function selector. The duration can also be set from the patchboard connection.

Mode “Repetierend Rechnen” (Repetitive Run)

If no specific time limit is set, the computer operates between “Reset” and “Halt” in a repetitive run. The duration of each computing run is between 10 ms and 100 s; the patchboard automatically sets this duration.

Mode “Rechnen mit Halt” (Run with Halt)

The “Rechnen mit Halt” (Run with Halt) function enables immediate stopping of the computing run at any desired time. All computing elements are frozen, and the established values can be read at the single amplifier outputs. These values can then also be converted to digital form by the Digital Attachment.

Mode “Steuereinheit” (Control Unit)

The “Steuereinheit” (Control Unit) mode allows the computing time to be controlled by the Verknüpfungsbaustein (logic unit) through either automatic or electronic means.

Mode “Null”

The “Null” (Zero) mode — in combination with the Verknüpfungs-Baustein — allows testing of the computing elements and checking of the analog connections.

Mode “Statisches Prüfen” (Static Test)

The “Statisches Prüfen” (Static Test) mode places the test probes on the computing elements and enables operation control.

Desk Analog Computer RA 742

[page 10: photograph of the RA 742 desk analog computer]

Application

The desk analog computer RA 742 is the younger Gerät of the newer computing machines of the series RA 710 and RA 742. It is even more suitable, in combination with the earlier models, for the most demanding simulation tasks.

• Simulation of stationary and transient partial differential equations
• Simulation of dynamic processes of any physical-technical description
• Simulation of complex non-linear functions and processes

In contrast to its predecessor it is even more flexible, and together with the analog programmable patchboard can also handle particularly large computing tasks. For tasks involving up to 30 Rechenwerte (computed values), immediate digital readout is possible through the digital attachment DEX.

Special Features

• Wide bandwidth of the computing amplifiers; quick computation of computing runs of between 10 ms and 100 s
• Three free-selectable integration time constants
• Possibility for immediate program storage through both the slow (continuous) and the non-continuous (digital) attachments DEX
• Continuous adjustability of the Rechenelemente (computing elements) through Kanäle (channels) and electronic Richterverstärker (reference amplifiers)
• Analog and digital computation through direct measurement via Digital Attachment DEX 100
• Automatic operation control through exchangeable patchboard

Operating Controls

• Operation controlled by illuminated pushbuttons
• “Reset,” “Einzel Rechnen” (Single Run), and “Halt” with external-control and timing capability
• Readout ready output (for connection to the Digital Attachment or other external units from which automatic operation switching is to be initiated)
• Generator for clock signals, which the Digital Attachment or Oscilloscope can use
• Trigger output for starting a recorder or oscilloscope
• Single-element function test by convenient switching; this switching can also be used via the patchboard
• Automatic operation control through interchangeable patchboard

Computing Elements

The computing elements — adders, integrators, or summers — can be used at each of the two selected types. Summers, integrators, or adders can be used simultaneously; and two compute amplifiers can be interconnected so they can alternately serve as adder and integrator.

For each type, up to 30 parallel computing runs can be initiated. Summers or integrators can be used alternately; and the computing amplifiers can be wired so that each can serve alternately as an adder and as an integrator.

Coefficient Potentiometers

The coefficient potentiometers operate with a Handpotentiometer (servo/manual potentiometer), can be read without ambiguity, and allow a precise reading of coefficient values. They can also be used for electronic scanning (the coefficient potentiometer also serves simultaneously as an address and coefficient potentiometer).

Multiplier

There is an electronically adjustable servo (precision) multiplier with four functions available. Through the appropriate programming, the parallel-multiplier networks can be set to between 10 and 30 Stützstellen (support/break points), settable from the desk-computer panel or electronically.

Variable Function Generators

The variable function generators are used to preprogram arbitrary curves with up to 20 Stützstellen (break points), settable. Each function element consists of the 21 Stützstellen of the computer, of which the Kompensationseinrichtung of the computer or of the Digital Attachment can set 100%.

For the function generators, the following types of functions are available:

Function	Count
Networks for 5 fixed functions
Quadratic functions: Y = X²	(4)
Cubic functions: Y = X³ or -X³	(2)
Cross-multiplication: Y = 2·XY or ¼·XY	(2)
Sinus-simulation (Y = sin X)	(2)
and
Article-simulation: Y = |X|	(1)
Logarithm function: Y = lg 100 X	(2)

For further computing applications, the following types are also available:

• Two patchboard networks | (8)
• Two computing elements (settable mechanically or electronically) | (4)
• Readout potentiometers | (2)
• Universal-functions (diagnostic) | (4)

For further computing applications, two zero-point quantities are available.

Patchboard

The arrangement of the computing elements — their inputs and outputs — on a single swappable patchboard allows a problem to be pre-programmed on one patchboard and all connections made through coefficient-potentiometer wiring. It is also possible to save any wiring differently through the patchboard. All Rechenelements of the desk computer are accessible via the patchboard; the connections of the input and output of the problem amplifiers as well as the connections via the function panels can be preset before the actual computing run and then activated all at once by the patchboard. The patchboard is automatically connected for all program operations and for the output of the computing elements in the Kompensationseinrichtung (compensation device).

Controls

The built-in controls on the desk computer illuminate the computing elements on the patchboard. They can be switched together as “Reset” and “Pause.”

The pushbutton “Pause” at the Ausgangspanel (output panel) of all computing ranges — the specified Pausenwerte (pause values) — lets the integrators to be frozen to the programmed computing run values. The duration can also be set from the patchboard.

[page 14: photograph of the RA 742 control panel]

Mode “Einzel Rechnen” (Single Run)

By pressing the “Einzel Rechnen” button the computing run is started; it carries out a continuously variable automatic extension of 1 to 10 seconds or any desired longer duration according to the function selector. The duration can also be set using the patchboard.

Mode “Repetierend Rechnen” (Repetitive Run)

If no specific time limit is set, the computer operates between “Reset” and “Halt” in a repetitive run. The computing run duration is between 10 ms and 100 s; the patchboard automatically switches the duration.

Mode “Rechnen mit Halt” (Run with Halt)

The “Rechnen mit Halt” function allows the computing run to be stopped at any desired time. The computing run is then instantly stopped and set to Halt-Stellung. All Rechenelemente are frozen, and the set values can then be read at the individual amplifier outputs. These values can also be converted to digital form using the Digital Attachment.

Mode “Steuereinheit” (Control Unit)

The “Steuereinheit” mode allows the computing time to be controlled by the Verknüpfungsbaustein through either automatic or electronic means.

Mode “Null”

The “Null” (Zero) mode in combination with the Verknüpfungs-Baustein allows testing of the computing elements and checking of the analog connections.

Mode “Potentiometer Einstellen” (Potentiometer Setting)

In this mode the Potentiometer-Taste (potentiometer button) sets the all coefficient-potentiometer values for the computing elements.

Mode “Rollen”

This mode is used in connection with the Verknüpfungs-Baustein for testing of the computing elements, and control-programme processing with more accurate Übertragung (transfer) and then matched to other more accurately processed results.

Mode “Statisches Prüfen” (Static Test)

The “Statisches Prüfen” (Static Test) mode places the test probes on the computing elements and enables operating control, with measurement and comparison of the analogue connections.

Digital Attachments DEX 100 and DEX 102

[page 16: photographs of the DEX 100 and DEX 102 digital attachments]

Application

The Digital Attachments DEX 100 and DEX 102 serve the purposes of digital operation in analog computers and the display of digital readings.

This device is used in the most varied application areas in industry and for research purposes:

• Commissioning and tuning of analog computers
• Setup and configuration of problem configurations and programs
• Measurement and display of calculation values
• Configuration of digital non-linear functions for the desk computer
• Setting and display of the calculation values and all coefficients of the desk computer
• Troubleshooting of analog setups

Digitale Interfacing for Desk Computers

The primary use of this device in the context of analog computers is as a digital counterpart — this is also the purpose for which the Digital Attachment DEX 100 for desk computer RA 710 and the DEX 102 for desk computer RA 742 are each adapted — so that each is capable of the highest level of flexibility for full digital-to-analog programming.

Special Features

• Compact and reliable design
• Greater flexibility in Programming of the Digital Patchboard possible
• Possibility for programming without Unterbrechung (interruption), settable
• Variable setting of the Programmierstecker (program plug) and Programmierschalter (program switch)
• Safety against incorrect wiring

[page 17: continuation of DEX 100/DEX 102 description]

Application (continued)

The Digital Attachments DEX 100 and DEX 102 fulfill functions in the most varied application areas of analog computers for experimental purposes and for demonstrations:

• In the most varied applications in industry and for research
• Setup and readout of analog configurations and setups
• Digital configuration of non-linear functions for the desk computer
• Setting and display of the computing values and all coefficients of the desk computer
• Troubleshooting of analog computing setups
• Commissioning of new problem configurations

Interface to the Desk Analog Computer

The main use of this device lies in its interfacing capability to the desk analog computers. The Digital Attachment DEX 100 for desk computer RA 710 and the DEX 102 for desk computer RA 742 have each been adapted to the respective device, so that it can work with the highest level of flexibility for full digital-to-analog programming. The Taskgeräte (task units) DEX 100 and DEX 102 that are to be used, also act as digital attachments for the desk computers RA 710 and RA 742 respectively — namely primarily as the computing-value display.

Special Features

• Compact and convenient design
• Greater flexibility in Programming of the digital Patchboard possible
• Possibility for program operation without interruption
• Setting of the Programmierstecker (program plug) and Programmierschalter (program switch) as a variable option
• Security against incorrect wiring

[page 18: description of DEX 100/102 operating features and use in education]

Task (Purpose)

The two devices are each placed in their Gehäuse (housing) and connected to their Maschinenbelegung (machine assignment). The active part of the Programmierstecker is then placed on the “Pause” button so that this Pausenwerte (pause-value) of the programmed Integratoren (integrators) freezes the computing run values. The patchboard sets the duration automatically.

Mode of Operation

The Taskgeräte contain Flipflops, Zähler, Vergleicher, and Relaxationsgeneratoren (flip-flops, counters, comparators, and relaxation generators). These Schaltungsgrupppen (circuit groups) are wired appropriately and every Komplex (complex) can be activated by switches, so that the two states “0” and “1” can be set. Each Relaxationsoszillator (relaxation oscillator) allows the two functions to be executed within a time of 10 ms to 1 s. Alternatively, an external time signal can be used.

The Taskgeräte hold the Schaltung (circuit) for the Flipflop. This switching state allows a Sicherheitseinrichtung (protection device) to monitor the Leitungsverbindungen (line connections) and at the same time a Vergleichsglied (comparator element) to be set to the first state.

By Schalter (switches) on the Flipflop, the Schaltungszustand (switching state) of the analog Rechenmaschine (computing machine) can be monitored and compared. Simultaneously an Analogrechnerbenutzer (analog computer user) can set the Normierungsfaktor (scaling factor) of the analog machine.

Educational Use

Students are given the following information on the Flipflop: Zähler, Vergleicher, Relaxationsgeneratoren. These circuit groups are interconnected with each other, so that with appropriate switching, the two states “0” and “1” can be set. Each Relaxationsoszillator allows the two operating states to be realized within a time of between 10 ms and 1 s (also alternatively through an external time signal).

The Taskgeräte serve the following educational purposes for the expansion of analog computer capability:

• Steuerung von Rechenabläufen (control of computing sequences)
• Simulation of individual components of the analog computer
• Setting of Normierungsfaktoren (scaling factors) of the analog machine
• Setting of analog Rechenmaschinen (computing machines)

Each Digitalelement can bring about an analog Sicherheitseinrichtung (protection circuit), enabling verification of all running test conditions and integration with a second comparator element.

Nonlinear Networks — NNT 740

Application

The solution of many problems on a desktop computer requires approximation of nonlinear elements or implementation of nonlinear functions in a simple and space-saving manner. The NNT 740, a product of AEG-TELEFUNKEN, meets this requirement with its versatile function networks and enables the combination of these function networks in any desired combination.

Construction

The NNT 740 unit comprises its own network chassis. Several units can be stacked and plugged together in a rack. The network chassis holds up to eight function modules, with up to two Abscissa modules and up to two slider-based function modules. In these chassis, the network programming modules and trimmer potentiometers for programming are accessible from the front.

Description

The basic unit has the following design:

• 8 diode-approximation modules ARV 791 with potentiometer adjustment, selectable by an Analog/Digital switch
• Programming via a trimmer potentiometer

---

[page 20: continuation of NNT 740 description]

• 32 function modules, which can be supplemented by subsequently ordered components. The Abscissa values for these function modules must be set so that the specific functions can be approximated most accurately:

  • Networks for fixed functions:

    • Parallel multiplication X · Y (4)
    • Square function: X · X² or − X² (4)
    • Root function: √X (4)
    • Cosine function: X · cos x × X (2)
    • Arc-sine function: arc sin X (2)
    • Logarithm function: ½ lg 100 X (4)
    • Log-power function: −½ lg 100 X (2)

  • Networks for variable functions (adjustable characteristic curves):

    • It is possible to insert up to 5 different cards per chassis, which can each implement a variable function. The desired function is thereby approximated by means of graduated steps.

  • Two special networks (8)

  • Two comparator modules (8) (address mechanical or electronic)

  • Programming elements (8)

Electronic Resolver — ERS 801

Application

The Electronic Resolver ERS 801 serves as an accessory for the Nonlinear Networks NNT 740 as well as for the precision integrators RA 770 and RA 803. Through the simple connection with the AEG-TELEFUNKEN desktop computers, it allows:

• As an accessory, it permits the simultaneous representation of polar coordinate values in rectangular form and vice versa.
• Conversion of the potentiometer setting in the AEG-TELEFUNKEN Precision Integration equipment to an angle value in a simple manner.
• Possibility of using the freely available computing capacity as a backup.

Special Features

• Low noise and high Nullpunkt-conformity (zero-point accuracy) through the variation of voltages in Cartesian coordinate form in the range up to ±10 V.
• Very high accuracy of the resolver.
• Reproducible resolver accuracy with optical electronic components.

Construction

The Electronic Resolver ERS 801 has its own housing chassis. Analog input and output signals as well as the Steuereingang (control input) of the computing unit are accessible from the front. The SFV 808 (4-quadrant resolver) is required as an Analog-Program block and is located on the rear side panel of the chassis.

---

[page 22: operating principles — ERS 801]

Operating Principles

Transformation of two polar coordinates (R, φ) into Cartesian coordinates (X, Y) is performed using the following equations:

• X = R · cos (φ · Y₁ − Y₂ · sin (φ))
• Y₁ = R₁ · cos (φ) + Y₂ · sin (φ)
• for i = 1, 2
• 1 ≤ M ≤ 1

Transformation of Cartesian coordinates (X, Y) into polar coordinates (R, φ) is performed by simultaneous solution of the equations:

• Z = X · cos φ − Y · sin φ
• 0 = X · sin φ + Y · cos φ
• when R = 0: φ = arctan Y/X

Electronic Delay Unit — LZG 102

Application

The Electronic Delay Unit LZG 102 serves as an accessory for the precision integrators RA 770 and RA 803 manufactured by AEG-TELEFUNKEN Technology. It is used for:

• As a delay element, it permits the simultaneous signal output from Wiederholbetrieb (repetitive operation) to be delayed. In this manner the result of a calculation can be used as initial conditions for the next calculation.
• Storing sampled computation results digitally so that these results can be read back again as analog values. The LZG 102 stores up to 120 words at 12 bits each. In this manner a computation result may be stored for the next computation run.

As a delay element, all inputs and outputs of the LZG 102 are connected to the analog computer and a digital delay value T_v, measured in milliseconds, is preset via a 10-Gang potentiometer.

The delay time T_v is calculated as follows:

T_v = W · K / f_0 / 0.1 ms

• W = word number
• K = 1 or 2 (switching-in mode)
• f_0 = sampling frequency

For memory operation with digital storage: up to 1000 storage positions (Speicherstellen).

Operating Modes

Verzögern (Delay): The input signal must not exceed ±1 V. Upon activation of the A/D-monitor and if the 8-Position-level is used, the D/A output is applied to the output.

Umlauf (Recirculate): The digital signal is read out; at the same time it is fed back into the memory and again written in.

Laden (Load): After activation of the Startfunks and after a sufficiently long waiting time, a clearly defined number of entries is read into memory. These are stored in groups of 10 words upon each Speicherzugriff (memory access) to be read back later.

---

[page 24: LZG 102 continued]

The operation is then performed and, as before, the Analog computer output is connected again. The delay time T_v, which is set by an external 10-Gang potentiometer T_v0, can be calculated:

• T_v = W · K / f₀ · 0.1 ms

As Delay element:

• T_v1 = input voltage upon T_v1 = 1
• T_v2 = for 1, 2, 4, etc. … is an Ausgang (output) value

Upon activation, the A/D monitor and if a 3-Position value level is applied, the D/A output is evaluated.

Verzögern (Delay): The input signal must not exceed ±1 V. Upon input of the A/D monitor and if the 8-Position-level is used, the D/A output is applied to the output.

Umlauf (Recirculate): The digital output value is read back; at the same time it is re-entered in the memory.

Laden (Load): After activation of the Starttaste (start button) and after a sufficiently long waiting time, a defined number of words is written into memory. These words are stored in groups of 10 words and can subsequently be read back.
