Extension:
The Floppy Disk may be extended up to 4 drives (2 units) using the daisy-chain connection. It is
therefore important to change the connection of each unit if the extension is made. The extension
should be done according to "Method of extension" described hereafter. A wrong connection
destroys the drive signal circuit. When extending the disk, an exclusive extension unit MZ-80FDK
must be used.
Ambient temperature:
The diskette used as a recording medium for the MZ-80FD is sensitive to temperature change:
easily expanding or contracting; therefore, the ambient temperature should be kept below 25°C
during continuous operation, and below 27°C during intermittent operation.
Power supply:
Supply voltage should be local voltage. Excessively high or low voltage could result in faults and
thus insufficient performance.
Do not connect the system to the same power line as other apparatus (e.g. a large-scale motor)
which cause noise. If the system malfunctions due to the noise from the power line, connect the
system to the power line that has been cleared of mixed noise using a power line filter. Turn on or
off the system power supply while the diskette is out of the drive, otherwise a malfunction occurs.
Humidity and dust:
The Floppy Disk, a precision machine, is easi Iy damaged by excessively high humidity. Do not use
this unit in a location that is high in humidity or is dusty. (Working ambient humidity range: 20% to
80%)
Water and foreign matter:
It is dangerous to use this unit with water or other liquid or metallic objects such as a needle, pin
or the like remaining therein. Take care not to allow any extraneous matter to get into the unit.
Especially if any liquid (including water) or powdery matter gets into the unit, be sure to contact the
dealer from which you have purchased the unit.
The same caution is required for the diskette. Do not operate the Floppy Disk while smoking or
drinking.
Installing conditions and shock:
The Floppy Disk consists of precision mechanism and electronic parts. Do not use it in a location
that is subjected to too !.igh or too low temperatures, radical temperature changes, much vibration or
dust. Do not give any shock to the unit by violently putting or dropping object(s) on it. Keep this unit
away from loudspeakers, televisions, tape recorders or other magnetism-generating apparatus,
otherwise it may cause a malfunction, or data or text recorded on the diskette may be erased.
Only operate the unit on a level surface. Locate the signal cables (flat cable, etc.) as far as possible
from other apparatus and power cords.

1. Connection with interface
Insert the interface card (option: MZ-80FI/O) into the Interface Unit (option: MZ-8011O) with its
parts-fitted side up - any of five card connectors in the interface can be used. Then connect the flat
cable (option: MZ-80F15) with the interface card: pass one of the connectors of the flat cable into
the interface unit at its rear part, and connect it to the connector on the interface card with their
polarity marks aligned. A polarity key is attached to the connector, so take care not to connect the
connector the wrong way, otherwise the polarity key is damaged. (See Figure 2.)
Then connect
the flat cable to the input connector (printed with "IN") at the rear side of the
Floppy Disk with the polarity aligned.
Last of all, connect the accessory braided wire between the MZ-80K and the FG terminal of the
MZ-80FD. To connect to the MZ-80K, fasten the braided wire with the screw to the left threaded
hole on the rear. Refer to Fig. 3.

2. Method of extension
It is possible with Disk BASIC to drive two Floppy Disk units (four drives). Use the extension unit
MZ-80FDK (drives 3 & 4) when making the extension. (Please order the extension-use unit from the
dealer specifying it as "an exclusive unit for extension".) The use of a unit other than the
extension-use unit may result in damage to the signal circuit of the Floppy Disk.
Given below is the extension procedure. Carry out the task observing this procedure.
a) Remove the flat cable from unit 1 (drives 1 & 2).
b) Connect the flat cable removed in a) above to the input connector (IN) of unit 2 (drives 3 & 4)
which is for extension use. (See Figure 4.)
c) Connect the one connector of extension-use flat cable (MZ-80F05) to the output connector
(0 UT) of unit 2 [for extension use] .
d) Connect another connector of the said flat cable to the input connector (IN) of unit 1 to which
the flat cable removed in a) has been connected.
e) Connect the accessory braided wire for MZ-80FDK between the FG terminal of the MZ-80FD
and one of the MZ-80FDK.
f) That is all. Be sure to al ign the polarity marks correctly when connecting.

Fig. 4 How to Extend the Floppy Disk

All the physical operations needed are to turn the power on or off, and to insert or remove the
diskette: every
other is carried out through the computer. For the Disk BASI C, refer to the
Instruction Manual of MZ-80FMD (option).
Insertion of diskette:
1. Take the diskette out of the envelope.
2. Open the front door of the Floppy Disk with your finger (See Figure 5).
3. Insert the diskette:
put it with its label up into the drive and push it till it will go no more. For the
inserting direction, see Figure 6.
Removal of diskette:
1. Open the front door gently and take the diskette out.
2. Put the removed diskette into the envelope, and put it back in its case.

Fig.6 Operation 2
1. Since an anti-crunch mechanism is used in the front door, the front door won't close unless the
diskette
is fully inserted. If not perfectly inserted, take the diskette out and insert it again
properly.
2. The Floppy Disk is provided with write-protection (which prevents the machine from wrongly
writing to it). When the write-protection notch of the diskette jacket is covered with the
write-protection label, improper writing to it is prevented. In normal use, do not cover the
write-protection notch with label or the like.

Handling the diskette
1. As a recording medium:
As a recording medium for the Floppy Disk, a
5.25-inch diskette stored in
an exclusive jacket is
used. Use the SHARP option diskette (option:
14--- 133.3mm ---.I

Index hole
+- ___ +-_ Head window
Fig. 7 5.25-inch Diskette
Do not touch the recording surface of the diskette with
fingers as this can cause reading and writing errors.
Storage temperature: 4°C to 50°C (ambient temperature)
Do
not expose it to the direct sunlight, nor put it in a
place where the temperature is over 50°C, otherwise the
jacket
is likely to warp and distort.
Insert the diskette straight into the unit till it stops. Then
close the front door carefully. Rough handling can damage
the diskette.
Do
not bend or fold the diskette. A deformed diskette
makes reading and
writing impossible.

3. Notes on the storage of diskette:
Envelope
The index label should be filled in before it is attached to
the jacket. If it is filled in after it has been attached to the
jacket,
use a soft-point pen. Do not use a ball-point pen,
pencil.
Do
not handle the diskette or Floppy Disk while you
smoke
or drink. If the diskette is soiled, the data or programs
stored on the diskette may
be spoiled.
Never
put a magnet near the diskette. A magnet ring or
magnet necklace may also affect the stored data. Be sure not
to use magnetic objects when the diskette is handled. Any
apparatus that generates magnetism should be also kept
from the diskette: for example, a monitor screen of a
computer, cassette tape recorder, home television set, etc.
When
not in use, be sure to keep the diskette in the
evelope. Form a
habit of putting the diskette into the
envelope
immediately after it is taken out of the drive. Such
a habit will prevent nearly all the problems resulting from
wrong diskette handling. The master diskette should be
loaded on the Floppy Disk only when it is used; and when
not in use, keep it in the envelope.
The envelope
is made of special material which works
against static
electricity, humidity, etc. So, make sure again
all
the diskettes are kept in the envelopes.
For keeping, put the diskette-containing envelope in the
container box, and
put it up in an erect position. Do not
keep it in an inclined position, or in· a position that may
make the diskette warp.
