COMPUTER MODE AND TIME SCALE CONTROL SYSTEM
3.1 INTRODUCTION
The modes of the analog computer are manually controlled by pushbuttons on the keyboard (see
Figure 3.1) or by patching logic signals to the proper patch terminals on the 0,12.1607 Control
Tray (see Figure 3.2). This chapter describes the analog mode portion of the keyboard and the
0. 12.1607 Control Tray.

Pressed, the appropriate computer operating modes are controlled by inputs patched to the
0. 12.1607 Control Tray. Other methods of controlling the computer can be provided as re-
quired. The linkage equipment, added to the computer to provide full hybrid computation with
a digital computer, is described in the manual provided with that equipment.

Consequently, when neither the operate nor the initial condition modes are selected, the com-
bination amplifier control circuits select the hold mode. Also note from the truth table that the
IC signal overrides the OP signal; if the OP signal is held at binary ONE, the integrators may
be switched between the OP and IC modes by switching only the IC signal.
If the PP signal is high, gating circuits in the control tray permit mode selection signals patched
to the OP and IC terminals to control the integrators. If nothing is patched to these terminals,
the integrators are automatically switched between the IC and OP modes at a rate determined by
the analog timer circuits. The OP and IC output signals from the control tray are connected
through bus bars and patching terminations to the integrator control circuits. However, indivi-
dual integrators may be controlled independently by applying a signal (external to the tray) to
the IC and OP control circuit inputs. A detailed description of the integrator control circuits is
provided in Chapter 3 Section 1 of the 580 Computing Components Manual (EAI Publication Num-
ber 00 800. 2057-0).
The analog time scale selection circuits are shown at the bottom of Figure 3.3. The integrators
in the 580 may operate at one of four time scales as selected by keyboard pushbuttons, by an
external device, and by integrator patching as shown in Figure 3.3. The selection signals are
stored ina register. The output of the register is connected to the TS bus line which controls
the TS relay in the integrator circuit. In the de-energized state the integrator is in the 1
sec mode. In the energized state the integrator is in the 2 millisecond mode. By patching
the FAST terminals (on the integrator patch block) together the four different time scales can
be accomplished. Table 3.3 indicates the different combinations and the resulting integrator
time scales.

3.4 THEORY OF OPERATION
The following paragraphs describe the analog mode selection and analog timer portions of the
keyboard, and the 0.12.1607 Control Tray. For ease of description these circuits are described
: plz.
separately.
3.4.1 Analog Mode Selection
The circuitry for the analog mode selection system is shown in Figure 3.4. The table at the
bottom of Figure 3.4 specifies the proper input and output logic levels of each flip-flop for the
different modes.
NOTE
Since the mode switches are momentary contact,
they must be held in the pushed position while
checking the logic levels at the input side of each
flip-flop.
The selection of a mode is initiated by depressing one of the analog mode pushbuttons on the key-
board. If two or more computers are slaved together, any computer in the group can control
the modes of the other computers if their remote (RMT) pushbutton has been depressed. Once
a particular mode pushbutton has been activated, the OR gates set or clear their respective
flip-flops. A combination of flip-flop outputs forces all of the inputs of the AND gate for the
mode selected to go low and its output is high. Since all of the circuits on the mode control
card are similar, only the IC mode is discussed in detail. When the IC mode pushbutton is
depressed, the input (pin 14) of gate 3a/4a and its output (pin 2) both go high. The clear input of
FF1 goes high forcing its 0 output terminal to go low. The high output of the IC switch is also
connected to inputs on gates 2a/4a and 1la/4a. The outputs of these gates force the set output (1)
of FF2 and FF3 to a low. The low signal from the set outputs of FF2 and FF3 and the low signal
from the clear output of FF1 are connected to pins 2, 1, and 14 respectively of AND gate 7a.
The three low level inputs on this gate forces its output and the IC output line high. The output
of gate 7a is also connected to inverter 5c. When the IC output goes high the output (pin 5) of
inverter 5c goes low, effectively grounding the input end of R5. The -20 volts through R6 to the
base of Q2 turns the transistor on grounding DS2 through the collector emitter path and the lamp
lights.
All of the mode control signals (except for the hold signal) are connected to the 0. 12.1607 Contro
Tray. (Although a hold signal is generated it is not used since the lack of an IC and OP signal
automatically places the computer in the hold mode. )

CHAPTER 3 COMPUTER MODE AND TIME SCALE CO
The static test (ST) signal is inverted by Q1 in the control tray and is applied as an ST signal to
the integrator and track/store trays.
The SP" output used in the integrator and track/store trays is generated by applying the SP signal
through buffer 2C and inverter Q1. The SP signal used in the integrator is generated by applying
the output of buffer 2C to the OR gate comprised of transistors Q2 and Q3. The second input to
the OR gate is applied through the override hold (ORH), patch terminal on the control tray. A
high at either input to the OR gate forces its output and the SP line low.
Since the OP and IC circuits in the control tray are identical in operation, only the IC circuit is
described. When the IC output from the mode control unit goes high the output of OR gate 4b
(pin 3) is forced low. The low is then applied to the input of inverter 3b. The high output from
the inverter drives the IC bus. Control of the IC and OP modes from patching terminals on the
control tray is possible if the PP mode on the keyboard is selected. The high PP output from
the mode control tray is inverted by 5b and applied as a low to pin 10 of AND gate 4b. A logic
high patched to the IC input is also inverted by another section of 5b and a low is also applied to
pin 9 of AND gate 4b. The two lows on the input of this gate force its output to go high. The
output of the AND gate (pin 8) is connected to the lamp circuit and the input (pin 13) of OR gate
4b. The high level at this point turns the IC lamp on and forces the output of OR gate 4b to go
low. Inverter 3b inverts the low output from the OR gate and drives the IC bus.
3.4.2 Analog Timer
The analog timer circuit provides a means of generating precise time intervals. The intervals
generated have time durations determined by the COMPUTER TIME SCALE switches and the
TIMER potentiometer and switches located on the keyboard. The time intervals established
by these controls may be used to control the analog modes of the computer for iterative or re-
petitive operation.
Figure 3.5 is a simplified schematic showing the major components of the timer. Refer to
this schematic for the following description.
Depending on whether or not the RMT switch has been activated, the time scale Signal is gener-
ated by an external device or by depressing either the 1S or 2MS pushbutton on the keyboard.
For purposes of description, assume that the time scale signal is to be generated from the key-
board. When the 1S pushbutton is depressed, the set input of the flip-flop, located on the
0.51. 0363 Rep-Op Time Scale Card, goes high, the 1 output of the flip-flop goes low and the 0
output goes high. The low at the 1 output is inverted by Q3 to the coil of relay K1 and the relay
is retained in the non-energized state, The high from the 0 output of the flip-flop is inverted,
essentially grounding the base of Q2 through R11, the base goes negative and the transistor con-
ducts causing the 1S lamp to light.

CHAPTER 3 COMPUTER MODE AND TIME SCALE CONTROL SYSTEM
When the 2MS pushbutton is depressed, the 0 output goes low and the 1 output goes high, the 2MS
lamp circuit is activated and the lamp lights. Transistor Q3 inverts the high level from the 1 out-
Put, the input and output of the driver are both low, and the relay is energized.
The condition of relay K1 determines the amount of reference voltage to be applied to the A
and A potentiometers. In the 18 mode the reference voltage is applied through 100K resistors.
In the 2MS mode the reference voltage is applied directly, through the relay contacts, to the
top of the A and A potentiometers.
This voltage, picked off the pots at the wiper, is fed through a series of resistors and field effect
transistors (FET) Q2 or Q9 to the input of the integrator. The integrator rate is determined by
feedback capacitors (C1 through C5) which are selected by the 0.1, 1.0, and 10X pushbuttons,
shown at the upper right of Figure 3.5.
Prior to operating the analog timer it is necessary to patch a high to the Run terminal! on the
Control Tray or to activate the PP pushbutton on the keyboard. If neither the RUN or PP inputs
(located at the bottom center of Figure 3.5) are high, the input and output of emitter follower
Ql4arelow. The inverter in series withQ14 has a high output and forward biases Q7 whichis con- |
nected as a diode. The high at the collector of Q7 also forward biases CR6 and CR7 connecting
a positive voltage to the base oftransistors Q3 and Q4. With the base of Q3 and Q4 negative the
transistors conduct and the gates of FET Q2 and Q9 are negative, pinching off the FET's, The
negative voltage at the gate of each FET also serves to saturate Q1 and Q8, grounding the IC and
OP input lines. The high at the emitter of Q7 is also applied to the inverter in series with Q13.
The low output of the inverter back biases Q13 (connected as a diode) and its output is at zero
volt. The base of Q12 is more positive than the emitter (-6 volts),
pinching off FET Q10 and saturates transistor Q11.

low, the IC line, which is complementary to the OP line, goes high (patch terminal A on the
control tray is high). The low OP signal turns on transistor Q5, its collector goes positive
turning on Q4. When Q4 is saturated its collector goes negative, pinching off the OP FET Q9
and grounds the FET input by saturating transistor Q8. The negative voltage used to pinch off
FET Q9 is also applied to the base of Q15, turning the transistor on and grounding the reference
through R27 and R29.
When the OP line goes low and transistor Q5 conducts, the emitter of Q6 becomes less positive
than its base and cuts off. With the drive voltage removed from Q3 it is in turn cut off, the
gate of the IC FET (Q2) is biased positive and conducts, putting the integrator in the IC mode.
The slight positive on the gate of the FET also cuts off transistor Q1 and the IC input line is
lifted off ground.
In the IC mode, the integrator feedback capacitors charge to a point that the comparator output
again changes state and goes high. The output of AR1 is inverted and the IC line goes low
(patch terminal A on the control tray goes low). The low on the IC line is inverted and the OP
line goes high (patch terminal A on the control tray goes high). The low onthe OP line cuts off
Q5 which in turn cuts off Q4 removing the negative voltage from the gate of Q9. FET Q9 is
turned on by a slight positive bias, Q8 and Q15 are turned off. When Q5 is cut off, Q6 and Q3
conduct andthe IC FET (Q2) is pinched off and Q1 conducts grounding the IC input signal.
3.4.3 Control Tray, Model 0.12.1607
The 0.12.1607 Control Tray contains control circuits used with the mode control operation of
the 580 Computer and control circuits for peripheral equipment. The following paragraphs con-
tain the theory of operation for those control circuits associated with peripheral equipment. The
circuits associated with the mode control of the computer are described in Paragraph 3.4.1.
3.4.3.1 Pen Control Circuit, The pen control circuit consists of a jumper
the DN patch terminal to pin N of connector A8 (P2). Cabling from that point connects the
control signal to the pen down circuit located in the plotter. A high (45 volts)

associated patching terminations are described in the sections or manuals dealing with their —

3.5 MAINTENANCE AND TROUBLESHOOTING
3.5.1 Maintenance
The mode control components require no routine maintenance or adjustments.
3.5.2 Troubleshooting
The problems that may develop in the mode control circuits are usually due to the failure of a
diode, transistor, or an integrated circuit element; rarely due to the failure of a resistor,

or other passive component. Often, a problem can be isolated to a single i,
1 of components simply by depressing the mode selection pushbuttons and oo e
mptoms, then referring to Figures 3.4 through 3.7. If the problem is more difficult to iso-
1 points that may be useful in evaluating symptoms are summarized below:
1. The lights beneath the keyboard registers are driven from the outputs of the
mode or time scale registers. If the correct pushbutton for a selected mode
is illuminated, it can be assumed that this register is functioning properly.
2. If the analog mode registers appear to be operating properly, but none of the
integrators respond to the mode selection, the trouble is probably in the
0.12. 1616 Control Card located in the 0. 12.1607 Control Tray. Select the
PP mode (analog) and patch an input to the IC terminal. The integrators
should be in the IC mode when this terminal is high. Similarly the integra-
tors should be in the operate mode when the OP terminal is high. Refer to
Figure 3.4 to determine the components that could cause the symptoms ob-
served.
