INTRODUCTION
This manual RA 770 D is divided into two parts:
Part 1: Operators Manual RA 770 D
Part 2: Technical Manual RA 770 D
The following operators manual refers to the Hybrid
Precision Analog Computer RA 770 D. Since there are
almost no differences as to the operation of the
RA 770 D and its preliminary modell RA 770 C, a lar-
ger number of instructions could be taken-over into
this operator manual. This means that all instruc-
tions given for RA 770 C also become valid for RA
770 D, respectively.
The modell number RA 770 D thereby designates the
further developped Hybrid Precision Analog Computer
RA 770, from device number 50 on, whereby important
improvements have been made as compared to its pre-
liminary modell.
Furthermore used are the following basic features
of the RA 770 C:
The mechanical design:
flexible adaption of equipment complement
by using drawers, plug-in units and printed
circuit boards, as well as interchangeable,
fully screened patch panels.
The 10 V - technology:
large bandwidth by low resistance level, high
longtime constancy because of low thermal
load of computing elements (no air-condition-
ning of computer system required).
Precision computing elements with error rate = 1074;
wire-wound resistors, capacitors with extre-
mely high longtime stability_and small tem-
perature coefficient (=10-5/°Cc).
Broadband operational amplifiers of silicon-Planar-
technology. Fast comperators, either with relays or
electronic switches.
Integrator control with electronic switches (EMC,=
electronic mode control).
Quarter-square multiplier with little product error.
Servo-set potentiometer with small resistance and
fast setting.
Control unit with digital selection system, digital
timers and fixed-wired control programs.
Digital adapter with interchangeable digital elements
for changing normal computing programs.
Additional drawers for special computing operations.
The additional drawer non-linear networks NNT 801
meanwhile is succeeded by model NNT 771, but is not
part of the delivery program. However, since its use
basically is possible with the RA 770 D, its opera-~
tion will also be explained beside that of the NNT
771 in this operators manual.
The Hybrid Precision Analog Computer RA 770 D provi-
des a larger scale of expansion possibilities. By
means of two expansion units RA 775 or two further
basic units RA 770 D used as expansion units, the
analog computer system RA 770 D can be expanded to
its triple size. Furthermore, two RA 770 D computers ®
can be switched in-parallel. To each of the two com-
puters again up to two expansion units can be connec-
ted, providing a six-fold computing scope.
For adaption of additional drawers whose computing
elements can be assigned to the analog patch panels
of the RA 770 D or of the expansion unit RA 775, the
expansion unit RA 776 is used.
In combination with the digital computer 90 - 40 or
the computer system TR 86, the Precision Analog Com-
puter System RA 770 forms the Hybrid Computing Sy-
stem HRS 900 or HRS 860.
The following operators manual informs the user about
equipment, control and programming of the Hybrid
Precision Analog Computer RA 770 D.
Further details such as technical design, initial
operation, specifications etc. of RA 770 D, RA 775
and RA 776 are given in the Technical Manual.

On request, two further units with 9 servo-potentio-
meters each can be added. Above this potentiometer
frame and also accessible from the rear side is a ma-
gazine for 10 comperators with 2 digital analog swit-
ches each. Below the magazine block, which is also
accessible from the rear, are two capacitor units
with 15 double integrator capacitors each (5/0.5 uF)
for the integrators.
The bottom part has locations for expansion units
(see table 2.2.1) with up to 6 units containing fur-
ther computing elements. When inserting a slide-in
unit, the required supply voltages are automatically
connected at the rear side via connector rails. Con-
nection of the signal lines of the computing elements
to the rear side of the patch panel takes place via
cables at the rear side of the table. At both ends
of the cables,there are contact bars for connection
at the slide-in units or patch panels, respectively.
Fig. 2.1/3 shows the connection panels at the rear
side of the power supply unit.
Connection panel 1 contains the contact knife bars
for the signal lines of the additional slide-in units,
for connection of expansion computers and external
output devices as well as the switch for operation
of the output devices. Further connectors are pro-
vided for the coupling unit and the comparator control.
Connection panel 2 provides the contact bars for the
signal lines to the coupling unit, to auxiliary com-
puters as well as the stepping switch lines and the
integrator control interfaces.
On the rear side of the power supply, there are a
socket for connection of the computer, protective re-
ceptacles for connection of external devices or auxi-
liary computers and circuit breakers. Additionally,
the operating time counter is mounted.

each card location group refer to table 2.2.2.
As to the use of part LOGIA, the following must be
observed:
if only the function
+}1g (-100X)
is used, the card occupies only part B of the part
location group, so that two further cards can be in-
serted on part A. In case also (or only) the function:
-S1g (100X)
is required, a soldering link between terminal b9 and
b10 must be inserted according to Fig. 2.2.2/1.In
this, the card location group is fully occupied. i

Drawer NNT 801!)
The drawers NNT 801 and NNT 771 provide 8 card loca-
tion groups for cards with non-linear networks as
well as additional amplifiers. Because of the diffe-
rent equipment range and operating features, the
drawers are described separately.
The drawer NNT 771 contains its own power supply unit
as well as locations for non-linear networks (8 card
location groups, i.e. 32 card locations) and for 3
amplifiers per card location group (i.e. 24 card lo-
cations). Of these optional amplifiers, 2 each can be
used as input inverter whereas one can be used as di-
rectly selectable output amplifier. Additionally, two
of the amplifiers can be used as free inverters.
Further details see chapter 4.4.2.1 and 4.24.3. A com-
mon network card (NW) belongs to 6 amplifiers each.
The card location groups and the respective amplifier
locations can be see from Fig. 2.2.2/2. As to the lo-
cations of the NN-drawers, see table 2.2.2 and the
described details.
8 of the 32 card locations can be simultaneously oc-
cupied with VAR-cards, independing of the number of
functions to be simulated.
The use of universal-breakpoint function A-BG1 re-
quires a wiring change within the drawer by reducing
the number of amplifiers being available.
This drawer is equipped with tow identical units, each
containing its own power supply unit and locations
for non-linear networks (4 card location groups, i.e.
16 card locations per unit), as well as for one opera-
tional amplifier per card location group. Further de-
tails concerning this additional amplifier see section
4.4.2.2, Each unit contains one network card equipped
with feedback resistors. The locations and assigned
amplifier locations are shown in Fig. 2.2.2/3. As to
the use of the NN-units, see table 2.2.2 and the
following explanations.
8 of the 32 card locations of the drawer can be equip-
ped with VAR-cards, independing of the number of fune-
tions to be simulated.
The use of the universal breakpoint function A-BG1
requires a wiring change within the drawer.

The UKF-magazine is accessible from the front below
a cover provided on the other left-hand side of the
magazine. It consists of 8 card locations, designated
with BGO-9 except the digits 2 and 7. This designation
thereby correlates to the arrangement of the UKF-jacks
on the analog patch panel. This means, that the digits
0,1,3,4,5,6,8,9 are the numbers of the address fields
in which the assigned jack field is located. Further
details see section 4.6.1.
The UKF-magazine can be equipped with the following

Hatched locations must not be occupied (however, both
RGF 104 and A-SV1A(B) can be used on the remaining
locations).
The magazine block contains 60 free-programmable ope-
rational amplifiers arrange in two magazines, as well
as the respective switching cards also being arranged
in two magazines. As to arrangement and equipment,
see Fig. 2.3.1/1 and table 2.3.1/1.
In general, the allocation of these elements to each
other and to the analog patch panel results in shor-
test possible line lengths. Two designation labels
contain the address indication of the respective amp-
lifier as well as the allocation of a switching card
to two amplifiers. In principle, a switching card
contains control elements and networks of two ampli-
fiers arranged opposite on the APF but with equal end
address number, e.g. for amplifier 3 of address field
0 (upper APF half) and address field 5 (lower APF half),
so that amplifier 03 and 53 have a common switching
card.

Noise Generator Amp-
lifier Magazine
In the noise generator amplifier magazine (RGV-ma-
gazine), amplifiers can be equipped, which are desi-
gnated as D-inverters (Da...Df)and which do not have
own jack fields. According to the table 2.3.3 and
Fig. 2.3.3/1, the resolver or NNE-jack fields can be
used for these amplifiers. Therefore, a cable must
be connected from St.2 or St.3 of the RGV-magazine to
one of the stated connectors of connection panel 1
(Fig. 2.1/3). The table shows the type of jack field
(NNE or RS) on which the input and output jacks of the
D-inverters are located. The position on the analog
patch panel can be see from the address field number.
As to the noise generators, further details are given
in chapter 4.8. According to the Fig. 2.3.3/2, RG1
is assigned to the upper APF-half, whereas RG2 to
the lower half, respectively.

Fig.
2-25
Fig. 2.3.5/1 shows the allocation of the card loca-
tion groups of drawer NNT 771 to the APF. Basically,
the left-hand drawer half is connected via two cables
to the upper APF half, whereas the right-hand drawer
half is also connected via two cables to the lower
APF half. Seen from the rear, first the B-locations
and then further to the front the A-locations are ar-
ranged within each card location group.

Pigs: 2533/2 Front plate of drawer NNT 771 (simplified)
The front plate of drawer NNT 771 shows in its top row
the zero potentiometers of the amplifiers, i.e. 3 zero-
potentiometers (A, N, X) per card location group. The
allocation thereby can be see from the designation of
the below mounted push-button. (With table computers,
this button serves for control. Control of the A,N,X-
inverters of the RA 770 C is described in section
3.6.3.2). The designation is identical to that of the
selection address of the directly selectable X-inver-
ter, whereby the tens digit corresponds to the add-
ress field number of the APF. The selection push-
button furthermore serves for over-amplification
indication of the respective X-inverter.
