• When the I C T R L I key is in depression, address $0000
through $OFFF and $DOOO through $FFFF become
the RAM area.
• With input of the command ":If' when the monitor
(ROM) is active, it is switched to the RAM.

• Because the floppy control area is mapped to $FOOO for
compatibility with the MZ-80K series, boot begins
from the adress $FOOO.
• Map configuration after boot will be considered sepa-
rately.
4-2. Memory controller (CRT C)
Both the momory controller and the CRT controller
are contained in a single chip custom LSI (M60719), it
has the following functions:
a. 8 x 8 dot characters are displayed on the CRT screen of
40 characters (horizontal) x 25 lines (vertical). Displayed
character font is dependent on the 4KB character
generator (ROM).
b. Manages the monitor ROM, DRAM, video RAM, and
peripherals (keyboard, timer, ETC.) mapped to the
memory.
c. Generates clock to the Z-80A microprocessor.
d. Selects the printer I/O port.
1) CRT controller
There are major variations of colour television systems as
described below.
1. NTSC system (Japan, U.S.A., etc.)
2. PAL system (U.K., Germany, etc.)
3. SECAM system (French, etc.)
Because of the different specification requirements above,
the MZ-700 may not be suitable for overseas operation.

Oata written in the VAAM
from the CPU is input to
01-08 via the bidirectional
buffer 5245.
Blanking period
To display characters on the CRT screen, the CPU writes
the character data (display code) to the 2KB VRAM-l
along with the control signal WR and the color data of
that character to the 2KB VRAM-2. In other words, as
the address ($DOOO ,.., $D7FF) is output. The character
data is supplied to the VRAM-l input (01-08)
via the bidirectional buffer LS245, and the data will then
be written when WE is low. The color data is also sent to
01-08 of the VRAM-2 to be written when WE is low.
