PC- l 600
1. Scope
(Memory modules usable: CE- 151, 155, 159, and 161.)
The CE·160 does not meet the upper grade compatibility test for software that uses the REM· ' because
of a functional restriction on the PC·l600 OPtional
printer CE·1600P, since the CE·l50 has two data
The PC-l600 has been designed with the following versatile
features:
, . The most of PC-1500 BAS IC software and the PC·1500
hardware options are compatible with the PC·l600.
2. Advanced technology gives the PC- l 600 new features
not available on the PC 1500.
rec order remote control terminals ( RE M-O and REM-1).
1-2. Implementation of functions that were not
feasible with the PC-1500
1·1. Compatibility with the PC-l500 BASIC
simulation mode
(a) Adoption of a 26-digit by 4-line alphanumeric LCD
unit.
(b) Operation speed of the PC· 1600 is approx. 2.5 times
faster than that of the PC· 1500 as a result of using the
general purpose microprocessor (Z·BO) as the main
CPU.
(c) Increased expansion module slot (two slots).
(d) Increased user memory area (11 ,834 Bytes user area
out of 16KB basic RAM area).
Ie) Implementation of the EIA. conforming to the internal
RS-232C interface for communication .
(f) Implementation of the system wake-up (modem phone
and timer started) and alarm functions.
(g) Adoption of the analog input, bar code reader input,
and external keyboard input interface.
(hi Use of the internal optical fiber (SIOJ interface.
For compatibility with succeeding models, most of software created in BASIC for the PC·150D can also run o:n the
PC· 1600.
(a) For display in the simulation mode. a single line on the
bottom of the display rows is subject for execution .
(b) In the simulation mode, the same character codes of
the PC-1500 are used.
(c) The PC-1600 must work with a variety of PC-1500
software programs that include an option controlling system. and the PC-16OO system bus signals are
upper grade compatible with the PC-l500 system bus.
(Consideration is given for the use of the CE-l50. 158.
and 162E.)
(d) The slot signals are also upper grade compatible; this
allows the use of the PC-1500 memory module on
1he PC-1600.

The following takes place when a reset is applied to the
SC7852 (AsfiN · Low).
<D ELH goes to high to indicate that the Z·80 is in
operation. At the same time, a reset is applied to the
LH-5803 . This allows the Z·80 to operate after the
completion of the reset_
® With the following instruction, the Z.aO hands down
the control to the LH-5803.
OUT(38H), A .... A is don't care.
HALT
After the execution of the above instruction, the Z-80
bus is set in the floating state. At the same time, £IR
goes to low along with RSTO, and the reset is cleared
to the LH -5803 to start its operation.
® With the following instructiory, the LH-5803 hands
down the control to the 2-80,
STA # A038H
A wait is appl ied to the LH·580J (L HWA1T"" High) to
stop the operation of the LH·5803. When E LH goes to
high, the LH-5803 bus is set in the floati ng state, With
this, the Z·80 starts to operate.

Before the Z-BO CPU sends a command to the sub
CPU, the sub CPU is asked if it is ready to receive the
command. If it is not, the Z-BO waits until the sub
CPU becomes ready .
The Z-80 assumes the sub CPU to be ready if the
BUSY input of the UART is high.
® Next, 8-bit command data are sent to the sub CPU.
The Z-BO sends the data on the DATA1-DATAB port
of the UART, which are received by the sub CPU
through A13-ROO. Unless ACK is returned withi n one
second, the Z-BO proceeds to the next processing.
® The Z.aO sends a pulse signal on DSTB of the UART in
order , to inform the sub CPU a command request,
which the sub CPU receilles of through the Klline.
With the Kt line of the sub CPU high. an interrupt
is sent to the sub CPU, and the command is processed
in the interrupt service routine.
(!) One of the fo llowing requests may be made depending
on the command issued from the Z·80.
(i) A request far return data
(ii) A request not to return data
The sub CPU then interprets the abolle to proceed to
the next step.
(i) A pulse signal is sent on Z9 after sending the
return data on R33- R20, to indicate completion
of the command execution.
(i j) A pulse signal is sent on Z9 to indicate receiPt
of the command.
In either case, the Z-80 waits for a high pulse signal
state on Z9.
The high state received on Z9 is then input to the
ACK line of the UART and latched internally, The
Z-80 checks the latch if it is okay.
® When the Z-80 accesses 33H of liD to request the
return data, it forces IORP to low so that the LR38041
gate array internal buffer is opened to send the return
data (R33- R20) on the Z.aO bus D7- DO.

The memory space directly accessible by the Z·80 is 64KB,
however, the memory space is expanded to 320KB for the
PC·1OO0 by means of bank selection. Bank selection is done
according to the contents of the Z·80 I/ F address 31 H.
When the Z·80 accesses a space in OOOH""3FFFH, bank
o or bank 1 is selected depending on the status in bit
o (bO) of the I/O address 31 H.
If bO = 0, bank 0 -+ PVaUT : 0
If bO = 1, bank 1 -+ PVOUT: 1
PVaUT (SC7852 output) is used to represent the chosen
bank (0 or 1). PVaUT is 0 when bank 0 is selected. It is
1 when bank 1 is selected.
Similarly, when the Z·80 accesses a space in 4000H '""
7FF FH , bank 0 '"" bank 7 is selected depending on the
status in the bits, b3 - b1. pvaUT, PU, and PT are used
to represent bank 0 thru bank 7.

® When KH goes high, the subcontroller starts to operate
assuming the start of the system. First, P3 is set low,
P2 low, Pl high , and PO low. Now, VCC is activated
because P3 and BFO are low, and the system reset
is applied with low PO and RSTIN states. The memory

When the subcontroller receives the system-off command from the main CPU, it confirms that both

are forced to low to disable the memory selection. If
KH is at high, the control proceeds to the system in
sequence.
Then, P3 and BFO are set to high to tum off the
system power supply. With this, all inputs and outputs

(1) If the BREAK/ON key is depressed, the all reset is
assumed and all internals are intialized.
(2) If the BREAK/ON key is not depressed, the reset is
assumed - the procedure to turn the system on from
the system-off state. The internals are not initialized
in this case.
It is possible to return reset from all reset by a request
from the main CPU, the Z-BO asks the su bcontroller
for the cause when the reset is applied, Processing

Regardless whether the system is turned on or off,
P3-PO are set in the input mode and are kept in the

subcontroller,
P3 is pulled up with the resistor.
P2 is pulled down with the resistor.
P1 is pulled up with the resistor.
PO is pulled dow n w ith the resistor.
While P2-PO are pulled down towards the non·active
direction, P3 is pulled up towards the systel1l-Qff. So,
the system's power supply is turned off in those states.
However, the power is supplied to the system while the
RESET switch is in depression.
7-4·2. Operation
(1) The LCD driving basic clock (217KHz) supplied from
CKO of the SC7852 is connected to the LCD common
driver. Without this signal, the LCD will burn out when
a DC voltage is applied to the LCD.
This signal is issued only during the system-on time
which appears immediately after the clearing of the
reset. As it is in a low state during the reset, a DC
voltage is added to the LCD during that period ,

then set in the input mode. So, a low signal is issued to
PA7 ,.., PAO and P86 at every 1/64 second to discri·
minate a key depression. In this instance, a low signal
is sent to all strobe lines to sense a key oepression.
When a key depression is sensed, that particular key is
distinguished after sencling a strobe to each line.
As the key input appears on KIN7 ...... KINO of the
SC78S2, a row of the keys in a low state is judged to be
the row at which the key entry occurred. Since input
not having a key entry is internally pulled up in the
LS I, it is in a high level.
(2) The HDS1202 LCD dri ver is for the 6800 series; the
timing clock E required for this interface is sent from
the SC7852.
The clock E goes high when the Z·80 acasses 40H5FH of 110. (It has a half clock delay against lORa
and its pulse width is 540 nanoseconds.)
But, the HDS1102 will not be $elected unless all three

When PRIME is at a low state, the RS·232C interface
outputs either in a high impedance or a low state (non·
active).
® When PRIME is at a low state, the SIO interface I/O
signals, SOF and ROF, are in an opposite polarity with
the UART input/output signa ls, TXO and RXO. The
start bit is high and the stop bit is low. So, both are
in a low state when no data are sent or received (UART
TXO and RXO are at a high level).
® When PRIME is at a high state, both SOF and ROF are
at a low level and non·active (stop bit I.
<f) When PRIME is at a high state, TXO and RXO of the
RS-232C interface are opposite in their polarity as are
those of TXO and RXO of the UART.
® When PRIME goes high, VOD is activated (RS-232C
interface high side voltage),
® The R5-232C interface input/output signals-CTS,
DSR, CD, and CI- are input to the UART (opposite
polarity), regardless of the state of PRIME (high or

VTHL and GND . As a result, the signal (e) changes
from low to high.
A signal transition is latched on the output side using
the pulse by means of the capacitor and characteristics
of the Schmitt IC for convenion of a logic signal into
the RS·232C interface signat.
The role of the R4 output is to prevent the possible
destruction of the IC4584 which may occur by an
accidental shon in connection with the RS.232C inter·
face or the connection of outputs together.
The capacitor C2 is for increasing speed for conveying
a change in the MN4584.
In order to change from high to low, the input must
be above VTHH. On the other hand, for the output to
rurn from low to high, the input must be below VTHl.
For the PC·1600, three resistors (Al, R2, R3) are

When the input (a) changes from low to high, the signal
(bl is sent to the VOO side as a pulse above VTHH by
means of the capacitor Cl between VTHH and GN D
as a normal level. As a result, the signal {el changes
from high to low.
@ On the other hand, when input (a) changes from high to
low, the signal (bl is sent to the VeE side as a pulse
8. Service precautions
Before servicing of the PC·1600, it is mandatory that you
release static power in your body by using the eanh band.
(When removing the key PWB from the top cabinet, it is
recommended that you secure the key tops and display
filter using cellopane tape.)
In order to open the cabinet, remove the RS.232C interface
connector cover, system bus connector cover, expansion
slot covers {1 , 2l, battery cover, batteries, and the ex·
pansion module .
Remove the five screws (see figu re) and slowly lift the
bottom cabinet with care so that you do not damage the
chips installed on the FPC PWB.
Now, you will see the signal levels. To get power by using
the AC adaptor or battery cells, connect the oscilloscope
probe to the negative side of the battery.

4. How to solder the FPC PWB with the key PWB
(1) Apply a thin layer of solder over the soldered portion
of the FPC PWB.
(2) Cut away 1.5 to 2.0 m illimeters of the tip of the FPC
PWB usi ng a knife or scissors, in order to check
whether the solder melted at the exposed portiOrt
of the key PWB will function when heating at (4).
(3) Remove the backing paper of the double tack tape

If the electrically conductive part of the rubber
connector were to be contaminated, it could
be a cause of a failure after the assembly of the

3. Generally. the FPC PWB should not be used again once
removed from the key PW8 because the soldered pattern
might separate from the board.
Since the key ?WB is bonded to the FPC PWB, to
remove, hold the shadowed portion at (AI with a double
tack tape and warm the area with a hair dryer; then
separate this portion from the solder using a soldering
pencil ,

c. Lift the PWB with your hand and carefully mount it
over the leads of the LSI. When the solder on the leads
melts after five to six seconds, remove the LSI from the
PYlB using a tweezers (or a small flat tip screwdriver) .
d . Clean away solder fragments remaining on the pattern
side of the LSI using a solder wick. Then, evenly apply a
thin layer of solder over the surface.
e. Apply a small amount of solder to the leads of the new
LSI , and solder the leads with care. Press the mold of
the LSI with your finger tip while soldering the leads .

components on the FPC PWB
(When a defective component is known without separating
the FPC PWB from the key PWB)
(1) Removing the LSI
a. Connect the LSI soldering tip to the soldering pencil
(see figure), set the surface temperature of the tool to
260o ±S" C, and secure it on the vise installed on the
workbench .

If it is heated above the given temperatlJre, it might
separate the circuit pattern or the FPC PWB itself.
The soldering pencil is held up to prevent solder, flux,
and gas from invading the back of the key PWB, where
the key contact pattern. the LCD rubber connector, is
mounted.
b. Evenly apply a proper amount of flux over the leads of
the LSI, and fill up the back side of the chip with solder.

9-5. TC8576F UART pin description
The TC8578P Standard Microcomputer Interface (SMI) is a
single chip C·MOS LSI which supports the R5-232C serial
interface and Centronics compatible parallel interface, both
of which are standard interfaces for microcomputers.
In the LSI is contained the RS-232C ART (Asynchronous
Receiver Transmitter), its "'ud rate generator, and the
Centronics transm itter/ receiver interface. Fo,
Con·
tronies interface, either tho transmitter or
recei ver
mode must be selected.
When the ART receives data f rom the CPU, the data are
converted into serial form and sent out on the TXO line.
On the othe r hand, the serial data received on the RCO line
are converted into parallel form before being handed to the
CPU. The ART is able to inform the CPU at any time of
the completion of sending the data received from the
CPU or the reception of the data to be handed to the CPU.
The clock input of the Ie is divided by a 4-bi t programmabie prescaler and becomes the internal clock (SYS-CLK ),
w h ich is further divided by the baud rate generator com·
posed of a 12-bit programmable divider, for the creatioo of
any baud rate of 50 to 38,400 bauds.
The transmission /reception handshake pins are prov ided for
the Centronics parallel interface. When the a-bit data are
received from the CPU in the transmit mode, a strobe of
the programmed pulse width is automatically issued. In the
receive mode, when data are received with a strobe singal
from the external source, a busy singal is returned to automatically inform the CPU .

Since the printer, cassette, and floppy disk drive are all
controlled by the PC-1600, the CE·1600P and PC·1BOOF
can not operate by itself.
Battery. however, can be recharged without intervention of
the PC· l 600.
A 32K B ROM within the CE·l600P contains the program
to operate the printer, cassette, and floppy disk drive.

Eight circuits shown in Fig .7 are contained in a single driver
circuit. The driller 1 is sued for drilling of printer X and Z
motors and the driver 2 is used for driving of printer Y
motor and and remote relay. (Two circuits are not used for

As shown abolle, the output transistor within the driver is
turned active in the period that the driver input signal
(signal from the gate array) is low level, so that current
flows across the load connected to the output terminal of
the driver. Fig.7 shows the equivalent circuit of the driver.

The PTMPG3308A ball point pen type, 4·color, plotting
printer consists of three stepping motors which are used to
control the direction X (horizontal pen movement), the
direction Y (vertical pen movement), and the di rection Z
(pen up/down and color change). Each motor is driven by
coils of A, B, C. and D. The CA detect switch is attached to
the left side of the printer for detection of a CR via the pin
PAS I of the gate array. The X and y motors are 1-2 phase
excited and the Z motor 2·2 phase excited.

1) The Pen Drive Mechanism
The pen drive mechanism consists of a Z-motor unit, a
Z·cam gear, an ejection lever shaft unit, a roller lever
and a ball point pen.
The pen's up/down movements are performed by the
rotation of the cam gear, whose motive power is tra nsferred to the ejection lever through a pin. Considering
the E point be low as an origin, the pen comes down
when the cam gear rotates three (3) steps along Z (+)
direction, and the pen CXlmes up when the cam gear
rotates three (3) steps from the pen-down position
along Z (-) direction.
7-2. Physical Characteristics of the printer
The PTMPG printer is composed of five parts: a frame unit,
an X~irection drive unit. a Y~irection drive unit, a pen
drive mechanism & color-chan ge mechanism, and a pen
take-out mechanism_ Each part is described below.
1. The Frame unit
The frame unit consists of a right side·plate, a left sideplate, support plate and paper guide. The lower end of the
frame is used for mounting.
2. The X·Direction Drive unit
The X ~irection drive unit con\ists of an X stepping motor,
an idler gear, a pulley gear, a pulley support rest (left)
unit, a pulley support rest (right) unit, a slider unit, and a
wire. The gear reduction ratio of the stepping motor and
pulley gear is 1 :13.9. A single pulse of the stepping motor
(18 degrees/360) moves the slider unit or pen by O.2mm in
the X direction. Power transmission from the pulley gear
to the slider unit is made by t he wire, which is tensioned
by a coil spring.

3. The Y·Direction Drive unit
The Y~i rection drive unit is the paper·feed mechanism.
It consists of a Y stepping motor, an idler gear, a platen
roller unit, a paper holder installing plate (left), and a
paper holder installing plate (r ight). The reduction ratio
between the Y stepping motor (Y motor) and the platen
gear is 1:.7.88. One pulse of the Y motor moves the platen
rolier, or reco rdi ng paper, by O.2mm in the Y direction.
(2) Z·Cam Gear steps
2) The Color·Change Mechanism
The color change mechanism is composed of a Z-motor
unit, a Z·cam gear unit, an ejection lever shaft unit, a
rotary holder which is in the slider unit, and a colorchange lever.
The color-change is performed by the movement of the
Z-cam gear gram from E point to 0 point and then the
reci procat ion of it between 0 and A points. The gear
of the rotary holder has 32 teeth, and eight (8) reciprocations of the 15·step movement make for a color
change once.

1) The Repair Technician
There are three levels of repair technicians: A, B, and C.
Each level is based on the level of knowledge about and
the skills required in repairing the PTMPG printer.
7-4. Maintenance and Repair
This section gives general instructions for handling the
PTMPG printer. Directions for maintenance and repair are
also included.
Level A:
This technician has little experience. He has general knowl·
edge of the principles of operation and structure of the
printer. He does not require extensive ex perience or skill.
For example, suppose the printer does not print. The l evel
A technicia n would first check to see if the solenoid were
energizing. If necessary, he would replace it or repair the
driving circuit. If the solenoid were enegizing properly,
he would check the battery voltage and, if neccessary,
recharge it.
level B:
This technician has some experience. He should have more
understanding of the principles of operation and structure
of the printer than the level A technician. He knows how
to d isassemble and reassemble the printer and can use
measuring instruments and tools to repai r it. For example,
if the printer were not working, the l evel B technician
could check the same things as the level A technician. In
addition, he would measure the length of the pen and replace it if it were too short. He could check the actuator, or
look for a broken spring in the solenoid, and replace the
un it if necessary. He could also replace the rotary holder
for the pen if it were defective.
1. Handling the PTMPG Printer
The PTMPG printer should be handled carefully and gently.
If you follow the instructions given below , yo ur PTMPG
printer shou ld give years of service. The sections below give
tips for proper handling of the printer.
1) Hold ing the Pr inter
Hold the fr ont and rear of the printer (marked w ith.Q. ),
as shown in Figure IX-1 below. Theprinter cou ld malfunction if it is held on the sides (marked wi th~). Do not
SQueeze the ejection lever shaft unit when you hold the
printer.

Ej ection
Lewr Shaft U nit
Figurl lX- l
2) Parts That Should Not Be Touched
• Do not touch the slider unit, except to take out the
l evel c :
Th is technician is highly experienced . He shou ld have detai led know ledge of the prinCi ples of operat ion and structure
of the p rinter, a h igh level of capabil ity in printer disassembly and reassembly, experience with measuring instru ·
ments and tools, and the ability to repair all parts of the
prin ter. The level C technician would perform all of the
tasks of levels A and B. In addition, he would replace
the ejection lever if it were bent, and replace the ejection
lever shalt unit, if the bearing were defective.
PO".
• Do not touch the wire. If you do, it may come out of
the pulley.
• Do not touch any shafts.
• Do not to uch the ejectio n lever shaft unit. If you do,
the relation between the connecting ring and the shaft
will be shifted. and the pen-up/down or color-change
fun ctions may not be performed.
3) Handling the Pen
Be careful not to drop the pen.
2) Repa ir Tools
Following is 8 list of the tools a technician needs to repair the PTMPG printer.
• Tweezers
• ET holders (ET4, En , and ET1.5 )
• Screwdrivers for precision instrument:
Phillips screwdrivers: No. 0 and NO. 1
Keystone screwdrivers: 1.4m/ m and 2.9m/ m
• l ong nose pliers or lead pliers
• Soldering iron and solder remover
• Special Tools:
a set of pen·stroke adjustment jigs:
Adjustment jig A OOP72-OO12/11 FG
Adjustment jig B OOP72-OO1311/ FG
Th ick ness gauge
2. Maintenance
The PTMPG printer should be cleaned every th ree months,
or after using 5 rolls of paper, wh ichever comes first .
Remove paper debris, dirt, and dust by suction (using a
vacuum cleaner). If necessary, apply alcohol or petroleum
benzine to rem ove dirt. Do no t use lacquer thinner, trichloroethylene or ketone solvents. They can damage the p lastic
parts.
Grease the printer, if necessary. Apply the grease to specified
parts onty,
3. Repairing the PTMPG Printer
This section covers instructions for repairing. the PTMPG
printer, includ ing descriptions of the levels of ski ll a tech·
nician must have to perform diHerent types of repai r jobs,
a list of the tools a technician w ill need, and a comprehen·
sive Repair Guide that shows remedies for problems that
might occur.
3) The Repair Guide
A Repair Guide is shown in the following pages. It is
divided into five columns for ease of reference. Descriptions of the five co lumns are shown on the n'ext page :
- 81 -

"Problem": This column contains the problem you have
identified. look here first.
"Cause" : This column describes the causes of a problem
under the specified conditions.
"level" : This is the level of expertise o f the repair technidan.
"Checking Method": This column describes the points
in the printer to be checked to locate the malfunctioning
part.
" Repairing Method": Th is column contains instructions
for repairing the printer.
l ook up "Problem" on Table X-l first to identify
your problem and find its "Cause." The reference
numbers of each "Cause" correspond with the ones of
the "Checking Method" and "Repairing Method" on

5. Brief description of floppy disk drive
The floPPV disk controller is implemented within the 2.5"
floppy disk drive, and the floPPV disk dri ving and head
seeking are done bV one motor. The floppy d isk is driven
by the belt and the head is seeked using the solenoid and
The reason why the reset signal is required at power on is to
hold it in the standby mode so as to avoid malfunction in
the floPPV disk controller inside the floppv disk unit.

Vo (+5V)
~
_ - .______~
The floppy disk controller and its peripheral logic are
contained in a single chip gate array (2700 gates) and the
read/write amplifier is also in a single chip LSI, which are
directly bus connected to permit a low voltage driving.
F loPPV disk format and write method are un ique to the
fl oppy disk. Though the floppy disk drive is for one·sided
operation, both sides of the media can be used .

L--------------------. 5VB
Fig. 3 R.lned power supply circu it
48 TPI
Fig.3 shows the regulated voltage supply circuit. In this
circuit, floppy disk unit's 5Ve (5V of am p) is supplied
from VP (battery voltage), because 5Ve can not be sup·
plied from vee on account of current restriction .
For the voltage of 5Ve is used with a voltage difference of
O.5V minimum against vee, the power is produced in
reference to 5VB through the differentiation circuit com·
posed of TR2 and TR3, not merely the regulator circu it.
5VB is a transistor output which is employed to turn on/off
vee with the MOTOR ON signal, and it has less voltage
drop caused in the transistor, as compared with vee , So,
0 1 is inserted to the output voltage feedback t ra nsistor
TR3 to correct 5VC to be 0.2 to 0.3 volts higher then 5V B
in appearance. (A schottky barrier d iode is used for D1 .)
5) Total tracks:

7) Access time :
One step 80 milliseconds from track 00 to track 15.
170 milliseconds to restore from track 15 to track 00.
Settling time:
50 milliseconds
8) Motor startup time:
0.5 second
NOTE : GeA is an ab breviation of of Group eoded Re·
cord ing. A single byte, 8 bits, data are d ivided into
two 4·bit data which is also converted onto a 5·bit
data. Thus, a single byte (8 bits) is recorded on the
media as a 1O·bit data.

resumes from 8).
11) After continuous test of test items, 1 thru 4, " OK"
is displayed when the test has been successful . If not
successful, the error is indicated on the d isplay and the
5VC voltage test location (pattern side)
printer.
12) After successful ending of test items, 1 thru 4, remove
the test media and set the side B of the media whose
write protect tab is set to WP,
13) Push the IENTE RI key now to check the funct ion of the
write protect switch . If it has been successful, the
de$Cl'iption is printed and the test terminates,
14 ) During this write protect test period, measure the +5VC
check point of the interface board with the dc voltmete r
to check that it is w ithin a range of 4.5VDC to 5,5VDC
(5VtO.5V).
7-5, Write protect test
This ten is eonducted to eheck prope r funct ioning of the
write protect of the floppy disk drive .
• Test description
• Check class 05 (CHECK 05)
Insertion of the media is checked after the motor has
turned on and functio ning of the w rite protect is
checked. That is, it checks that it is the media that
write protected.
• Check items
1) During the test (while the access LED is active).
measure the voltage across pads at two locations of
the pattern side using the de voltmeter (6 to 10VDC)
to ensu re that it is 5VDCtO.5VDC (4 ,5V - 5.5V).
2) When the access lamp goes out, make sure that 5VC is
now turned to OV .
3) After completion of the test, check the display
metsage on the PC-1600 that "O K" is on display.

Two program modules can be used at the same time.
When used as the program module, no user area can be
contained. But, if the module has been d ivided into a
program module and a user area using the INIT statement, only the declared user area conforms to the user
area of (1),
Creating the program module:.
After declaring the program area with the INIT state·
ment, the program is written or loaded to that area.
The memory protected CE·159, CE.161, or CE.1600M
must be used for the program module.

With this usage, the completed program or data are saved
into the memory module, to be loaded onto the user area
when so required.
If used as a RAM module, the module is not included in the
area.
CD The module that can be used the RAM file module is
the CE·161 and CE·l600M.
The RAM file module can be accessed free from the
main unit. While it is removed from the main unit, the
contents are retained by the internal battery .
• What program and data are contained within the RAM
file module can be known by means of the FILES
