4-1. Memory map
The MZ-800 has a different memory map depending on
the mode. To have compatibility with the MZ-700, it has
two modes of the MZ-700 mode and MZ-800 mode.

• Memory map at power on is in the MZ-800 mode as
in ®, but it changes to the MZ-700 mode by the
monitor ROM when the monitor program starts. After
transferring the CG data to the VRAM PCG area from
the CG ROM at @, the memory map then returns to
SFFFF L..._ _ _---'
• Depression of the manual reset switch assumes
memory map transition in order of ® ~ ® ~ @ ~
®, similar as in the case of power on.
• However, depression of the reset switch in conjunction with the I CTRL I key assumes the memory map of
@ after being changed once to the MZ-700 or MZ-800
mode depending on the state of the system switch. In
the case of the MZ-800 mode, it is set to the plane I.
IT (4-color mode) of the 320 x 200 mode.
®.
• When the system program is completed to load, the
memory map goes into the MZ-700 mode if the
system switch (SW1) is set to ON side. If set to OFF
side, it changes to the MZ-800 mode, then the
memory map as in @. During those changes, all
memory spaces are composed of RAM and isolated
from ROM and VRAM.

assignment of MZ-800 internal device.
See Table-2 for relation of internal device vs I/O
address.
4-2. Custom LSI
The custom LSI is a 100-pin single chip LSI on which the
MZ-800 memory controller (I/O controller) and CRT
controller, etc. are contained.
4-2-1. Memory controller
Used for the control of the memory bank. Addressing of
DRAM, ROM, and VRAM is conducted by selection I/O
address, $EO - $E6, using OUT or IN command.

4-2-4. Display address generator
1) Display address generation
• Display address increments from left to right as
beginning from the home position at the upper left
corner of the CRT screen (address $000). The first
display line dominates address $000 through $027.
Because a screen frame consists of 200 rasters, the
address at the right side of the bottom corner is as
follows:
(200 x 40) - 1 = 7999 = $1 F3F
• The address counter stops counting for a horizontal
flyback line and stored in the address latch circuit.
When the horizontal flyback line terminates, the
address latch output is preset in the address counter
(display address generator).
• Address is generated even while the vertical flyback
line is active and it makes the counter reset before
termination of the vertical flyback line.
4-2-3. Clock generator and timing generator
Oscillation from the crystal oscillator is divided to create
the CPU clock, horizontal sync, vertical sync, and display address control signals.
Since the low state of signal is used for NTPL (NTSCI
PAL selection) with the MZ-800, the CPU clock of
3.547 MHz is derived from the crystal frequency of
17.734 MHz by dividing it 1/5.
NTPl
1>-----'
2) Display address generation in the MZ-700 mode
• Because characters are displayed under the PCG
method in the MZ-700 mode, address is generated
for each character and the same address is used for
displaying of one character. The 3-bit horizontal line
counter is provided to count horizontal lines to
generate the address (LCO - LC2) for selection of the
character front.
Display address increments from left to right having
the uppermost left corner of the screen for the home
position.
Since 25 lines are used to develop displaying of
characters composed of 8 x 8 dots, the address at
the right of the bottom lines becomes $3EF.

3) Display address multiplexed with CPU address
• Address used to write data to the VRAM is latched in
order to avoid CPU wait. Display modes of 640 dots
and 320 dots are assigned by the mode switch
(DMD2).
• Display address is multiplexed with the VRAM write
address in the timing of DISP which has the timing
that the display address and CPU address may
become a pseudo cycle steal.

4) Line scroll
SOF = $O~ $28
Programming "SOF = $28" makes the display screen
shifted eight lines up. Data on the highest line
therefore shifted to the bottom line.
Programming "$28 ~ $0" makes the display screen
shifted eight lines down, and the line on the bottom
moves to the highest line.
4-2-5. Scroll
1) Scrolling is possible for both horizontal and vertical
directions by means of software offset.
The following four registers are use~ for scroll
control.
a. Scroll start address register: SSA (7-bit)
b. Scroll end address register: SEA (7-bit)
c. Scroll width register: SW = SEA-SSA (7-bit)
d. Scroll offset register: SOF (10-bit)
5) Screen split
Appropriate deviation of SSA. SEA, and SW permits
to divide the screen into three sections of ®, ® and
I
(
©.
Though the section ® is permitted to scroll, sections
® and © are not permitted to scroll.
See the figure to explain with.

2) Control of scroll starts by the initialization of the
scroll control register.
SSA = $0
SEA = $7D
SW = $7D
SOF = $0
Assume now that the top of the section ® is on the
5th line (40 raster) and the top of the section © is on
the 18th line (144 raster). Attention must be paid to
the fact that values SSA and SEA are used for
assigning lines. Scroll registers are set with the
following values.
SSA = $19
SEA = $5A
SW = $41
SOF = $0
In this occasion, it needs to initialize the screen that
has been displayed. "SOF = $5" must be programmed to scroll ® one line. Then, only the section ® is
shifted up, and the highest line of ® moves to the
bottom line of ®. Programming "SOF = $A" makes it
scrolled one more line.
SOF ~ SW
Scroll offset (SOF) should necessarily be within a
range of the scroll width. Display is not assured with
SOF set greater than SW.
3) Way of smooth scrolling
SOF = $0 ~ $5
Programming "SOF = $5" makes the display screen
shifted one line up.
The highest line (address: $0 - $27) is then assigned
to the lowest line ($1 F18 -.: $1 F3F).
As normal scroll involves updating of the data for the
lowest line, the data of address $1 F18 - $1 F3F are
updated.
SOF = $5 ~ $0
By reducing the value of SOF by "5", it makes the
screen shifted one line down.

Concept of the scroll control circuit
Scroll method
• Scrolling by means of VRAM address conversion.
Execution of scrolling by address conversion
• Scroll offset (SOF) is the count of lines which the CPU
gives to the CRTC. For instance, the following must
be observed to perform scrolling.
3-line scroll: SOF3 = OF x 3
5-line scroll: SOF5 = OF x 5
And, to scroll one more line after 5-line scroll;
5-line scroll: SOF5' = SOF5 + OF = OF x 6
Range of scroll
• y-axis programmable.
BASIC console command compatible
• x-axis fixed
Scroll sequence
• The scroll start address is termed "SSA" and end
address "SEA".
• Execution of scroll, with offset given from the CPU.
• One line (line S) starting from SSA disappears from
the display screen.
• A new line (line S') is added to SEA. Line S' is the
same refresh memory as the line S. The contents of
the memory was erased (nullified by the CPU) before
the execution.

• Display address DA is the signal created in the CRTC
display address generation circuit and arranged in
their order from the upper left corner of the screen.
The bottom right address is 1F400 in the 640 x 200
mode.
• Display memory address DMA represents the VRAM
address corresponding to DA.
Since scroll is executed by means of address conversion, the order of DMA may not be the same as DA,
necessarily.
• CPU address MA is the VRAM address that obtained
from the CPU through the CRTC. To lighten burden
on the CPU, a circuit is added to make order of DA
identical to order of MA arrangement.

4-2-6. VRAM data input/output circuit
1. Nothing intervenes for input and output of data in the
case of the MZ-700 mode.
2. MZ-800 mode
• Write
Read data (RD) from the VRAM and write data (WD)
from the CPU are subjected to logical operation
accordi'1~ to the direction from the write format
register (WF) and its result is written.

• Read
For plane read data from the VRAM, data to be read
by the CPU are arranged in accordance with the
direction of the read format register (RF).
As the PCG method is adopted for the MZ-700 mode,
the text and ATB areas are actually mapped to $0000
- $OFFF. So, the VRAM address has the following
relation with the display character position.

2) MZ-800 mode
As the bit map method is used for the MZ-800 mode,
it is possible to four screens of 320 x 200 dots and
two screens (maximum) of 640'x 200 data.
The cycle steal method is used for this mode.

* Logic circuit
Read data from the VRAM and write data from the
CPU are subjected to logical operation (OR, XOR,
RESET, etc.) and its result is used for the write data.

With the MZ-800, the pseudo cycle steal method is
adopted for VRAM accessing.

As shown in the figure, a next display data fetch and
CPU accessing are multiplexed during a display period.
Because accessing of the VRAM while characters are on
display causes the screen to blink with the MZ-700
mode, it awaits for blinking to complete before accessing of the VRAM. But, with the cycle steal method it
enhances faster screen processing as it enables to
access the VRAM during a display period. Because it is
not a complete cycle steal with the MZ-800 but timing is
taken using a wait in order to synchronize with the CPU
cycle for accessing from the CPU, it is therefore called
"pseudo cycle steal

CPU and VRAM accessing
1. Accessing of the VRAM by the CPU is carried out in
the cycle steal mode (MZ-800 mode only) during the
flyback period of the display under the control of the
CRT controller.
2. Even when there is no accessing from the CPU in the
CPU cycle, such as VRAS, VCAS, VOE, etc. are
outputted in the timing of the read cycle at all times.
3. Write to the VRAM is carried out after logical operation of the read and write data by means of the
read-modify-write method. But, in the case of the 320
x 200, 16-color mode, data are written in two CPU
cycles as there is a need of writing to Plane IV.
See separate paper for timing chart.
4. CPU wait
1) Write
• As there is a one-byte buffer in the CRT controller,
write to the VRAM from the CPU is carried out
through the buffer. But, actual write to the VRAM is

done by the CRT controller. Therefore, there would
be no need of wait under almost any condition in the
MZ-800 mode.
• Even in the MZ-700 mode, wait is issued when there
are more than two writes in a display period.

rn, and N. If it is "1" for more than two or
non-existence of the VRAM may not
assure the data read.
"1": Specified color search .....
"1" is retu rned for the bit of the color specified by
0/1 of I, IT, rn, and N.
NOTE: Depending on the display more, color
combination is permitted for the bit combination of L IT, ID, N; ID, N; I, IT; I; and
ID. Bit combination otherwise will be disregarded.
(ex. For the 640 x 200, 4-color mode,
combination becomes possible for I and
ID, and IT and N are disregarded.
• As the CRTC bus is completely separated from the
CPU bus, read and write of the VRAM is carried out
through the CRTC. Therefore, interfacing with the
CPU is done via the read register or write register in
the CRTC.
• VRAM access by the CRTC is done under the pseudo
cycle steal mode.
• Not only read and write are for the accessing with
the CPU, it permits to read multiple number of screen
data logical operational results and to write the
read-modify-write of the logical operational results
for the data already written. So, it has two registers
of the read format register and the write format
register.
• It permits CPU access to the non-display plane in the
display mode according to the BI A bit and it enables
selection of data buffer and two screens, when the
32 KB VRAM is used.

• As there are four 4-bit pallet registers provided inside
the unit, it permits choice of R, G, B, and I combinations, and it enables to make choice of any desired
two or four colors out of sixteen available colors.
However, in the 320 x 200, 16-color mode, choice of

sixteen.
• Only the conventional mode is applicable for the

An example of the pallet in use in the 320 x 200,
16-color mode
• Assume that the pallet register has been set to the
following.
PLTO = Black
PLT1 = Cyan
PLT2 = Red
PLT3 = Magenta
• When SWo is set to "0" and SW, to "0", the pallet is
applied to four colors in group 1 (ill = 0, N = 0) and
it results in the color as shown in CD of the table right
(yellow to cyan).
• When SWo is set to "0" and SW, to "1", four colors
of group 3 (ill = 0, N = 1) becomes the display color
set by the pallet.
• Therefore, any color can be chosen out of 16 colors
against four colors of color group selected by SW1
and SW2.
• For group other than selected by SWo and SW" the
color that I - N outputted on B, R, G, I is displayed.

Key strobe is issued through PAo-PAl to ~can the key.
As it is supplied to the decoder, it makes one of outputs,
0-9, set low. It is then added to the key matrix to scan
the line of the key depressed (vertical key matrix scan).
The line is in the low state, if it is in depression
(horizontal key matrix scan).
NOTE: In the ready for command state, PAo-PAl are
normally repeats to be low state and the decoder outputs repeats to be high state. But, since
the decoder is of an open collector type, it
would not permit to check high and low state.

Rotation of the cassette (dedicated) is controlled by the
8255 and its peripheral circuits.
For use of other than MZ-800 cassette tape recorder
type, it needs to short SENCE to GND, READ to
EXREAD, and WRITE to EXWRITE of the connector T-5.
Use of the cassette recorder of other kind may sometimes not permit proper loading and saving operation.
In such an event, adjust the volume and tone controls to
find the optimum positions. To meet the opposite
polarity of cassette tape recorder, there is a dip switch
provided. Changing the switch position makes TPSW
signal state changed so as to invert the signal waveform.

After the personal computer confirms that the printer is
ready to receive data at (<D), the data is then sent to $FF
port (PlO port B) at step (ID).
As reception of data is directed to the printer at step
(@), it makes RDP forced low at step (@) upon confirming that the printer received it (RDA=H). After this, it
awaits until RDA goes from high to low before transfer
of a next data. But, it is possible to transfer successive
data by interrupting the CPU at a falling edge of RDA,
since RDA is inputted to the RSTB input of the PlO,
when in the port B mode O.
It is also possible to interrupt the CPU referring to Port A
inputs. Though discussed above is the printer interface
methlod for the MZ compatible printer types, there is the
Centronics compatible method for parallel interfacing of
the printer. Since this method is basically the same as
the MZ mode, except that signal polarity is opposite.

The SN76489N is used for the programmable sound
generator which is controlled by the I/O port $F2. It is
write only. In order to permit smooth sound generation,
timer interrupt is applied using the 8253. For the
interrupt timer, the count 0 of the 8253 is used. The
counter 0 is used for creation of sound steps in the
MZ-700 mode, but, it is used for the timer interrupt
source of the PSG in the MZ-800 mode. Interrupt is
controlled by PA5 of the PlO. it is, however, possible to
mask the counter 0 output by PCO of the 8255, in order
to prevent sound generation during interrupt.

5-2. Operational description
The block diagram of the power supply unit is shown
above. It adopts the self-excitation ON/ON control
method. First, the source supply is rectified through the
noise filter and converted into direct current. As the dc
current is applied to the switching transistor, it causes
the transistor to start repeating ON and OFF. After the
dc voltage is converted into high frequency pulse, it is
added to the primary side of the main transformer
which causes to induce voltage on the secondary side.
This high frequency pulse is then rectified and filtered to
obtain the dc voltage of +5 volts. For control of output
voltage, the output voltage is compared with the reference voltage and its error is detected in the control
section. While the switching transistor is in the OFF
cycle, it makes the photo cuppler PC1 active by the
detecting signal of the control section for given period.
By adjusting control current of the drive circuit, it makes
the out put stabilized.

Cleaning
Dust deposit inside the power supply unit may becomes
the cause for overheat as it prevent heat dispersion,
which results in damage in component. Stains on the
fuse contact and connector contact may lead to contact
failure. So, it has to be cleaned using soft cloth dampened with alcohol or dry soft cloth.
5-4. Problem determination and sequence
Follow the next procedure to find the cause of trouble.
(1) Avoid removing the board to check. But visually
observe the board to check for open circuit line,
burnt resistor, fuse, and semiconductor chips in the
first place.
(2) If a defective item were found, it has to be replaced
with the new one. But. care must also taken as
there are possible defects in mUltiple number of
components.

3-1-1. At power on
At power on, more than 5V of pen up current is applied
for a period of lOrns, plus 5 and minus Orns, to move the
carriage 556 steps backward on the X-axis in order to
initialize the colour position. As the carriage is held at the
left margin after disengagement of the motor, it is then
moved 30 steps forward on the X-axis, then stepped back
30 steps again to check if the colour position detector
has been made. If not, it continues to move the carriage
30 steps forward on the X-axis, then return 30 steps to
ensure the made condition.
3-1-2. Colour change_ operation
To change colour, the slider makes three reciprocating
movements of 6mm (30 steps) at the left end of the X-axis
to move the pen position one step. When the desired pen
position is attained, it then returns to the home position.
Since the pen rotor makes a unidirectional rotation at
the left end of the X-axis, and is locked within printable
range, care must be exerted not to touch the rotor and
the slider.
3-1-3. Pen exchange operation
A pen needs to be exchanged with a fresh one when it
runs out of ink. In such an event, the pen is moved 485
steps forward on the X-axis from the home position with
the used pen located on the top of the rotor, then take
out the used pen, by pressing the pen release lever and
exchange it with a fresh one.
3-1-4. Motor phase and rotating direction
The arrow head indicates the forward direction for both the
X-axis and Y-axis.

3-2. Pen exchange method
It is more effective to save power to shut off current
while the X and Y axis motors are at a halt. But, there
may be a possible malfuction because of unsuppressed
vibration, if the current is turned off with a normal
pulse width. In order to prevent this, current is applied
excessively for more than the given hold time (tMH =
lms or more).
To remove pen, press the pen exchange button, when the
slider is at the right handside, push the pen release lever.
Motor
3-4. Colour position detector
The colour pOsition detector consists of a reed switch
and a permanent magnet and it may cause malfunction
owing to external vibration, and magnetic influence.
Especially, when deposit of alien matter or paper fragments is between the left end of the carriage and the
frame this may result in a failure of the colour detect
performance.
3-5. Character set
Push the pen release lever
Input of an undefmed code up to $20 is ignored. Other
undefmed codes are represented in hexadecimal notation
using the pen in a next color position.
Pin configuration (top view)
To install the pen, push the tip of the pen through the
ring of the return spring in the fIrst place, then push into
the holder. Upon completion, ensure that the tip of the
pen is engaged with the hole of the pen return spring.
If colour change is done when the pen is disengaged from
the hole, it may cause improper rotation of the rotary
holder as the slider makes contact with the pen. Do not
try to rotate the rotary holder by hand when installing
the pen during replacement of the pens.

The CPU sends data to the printer after confirming that
ARDA is in low state. Five micro seconds later, the strobe
signal ARDP goes high. The CPU confirms that ARDA is
in high state, ARDP is returned to a low state 14.5 micro
seconds later.

4. COlOR PLOTTER-PRINTER CONTROL CODES
4-1. Control codes used in the text mode
• Text code ($01)
Places the printer in the text mode.
• Graphic code ($02) ................................................ Same as the BASIC PMOOE statement.
Places the printer in the graphics mode.
• Line up ($03) .......................................................... Same as the BASIC PSKIP statement.
Moves the paper one line in the reverse direction. The line counter is decremented by 1.
• Pen test ($04) ......................................................... Same as the BASIC PTEST statement.
Writes the following patterns to start ink flowing from the pens, then sets scale = 1 (40 chr/line),
colour =0.
Black
Blue
Green
Red
DODO
• Reduction scale ($09) + ($09) + ($09)
Reduces the scale from 1 to 0 (80 chr/line).
• Reduction cancel ($09) + ($09) + ($OB)
Enlarges the scale from 0 to 1 (40 chr/line).
• Line counter set ($09) + ($09) + (ASCIIh + (ASCIIh + (ASCII)o + ($00)
........................................................................... Same as the BASIC PTEST statement.
Specifies the number of lines per page as indicated by the 3 ASCII bytes code. The maximum number of lines per page is 255. Automatically set to 66 when the power is turned on or the system is reset.
• Line feed ($OA) ....................................................... Same as the BASIC PSKIP statement.
Moves the paper one line in the forward direction. The line counter is incremented by 1.
• Magnify scale ($OB)
Enlarges the scale from 2 to 1. (26 chr/line)
• Magnify scale ($OC)
Reduces the scale from 2 to 1.
• Carriage return ($00)
Moves the carriage to the left side of the print area.
• Back space ($OE)
Moves the carriage one column to the left. This code is ignored when the carriage is at the left sfde
of the print area.
• Form feed ($OF)
Moves the paper to the beginning of the next page and resets the line counter to O.
• Next colour ($10)
Changes the pen to the next colour.
4-2. Character scale
• The character scale is automatically set to 1 (40 chr/line) when the power is turned on. Afterwards,
it can be changed by the control codes and commands.
• In the graphics mode, the scale can be changed within the range 0 to 63.
• The scale is set to 1 when the mode is switched from graphics to text.
