Generally it is working for the improvement in the ability
though it occurs
to pass from the appearance rest of IBM PC for several years.
The high resolution to indicate Japanese with 24 dot is especially
characteristic.
When the next high resolution standard of VGA is developed
in IBM,
the resolution of the Multi-Station was adopted.
It is a famous story.
As for the resolution of 16 dot edition, even the expansion
indication
mode of JX was adopted.
The structure of indication of Kanji
It is fundamental specifications it has the font of the Kanji,
and adds a font
to the memory more than software and to indicate it on the
hardware.
The Kanji font card of the option must be built in in this
inside of the body
by the model.
A Kanji font card became a Kanji ROM more than the model of
the middle,
and came to be carried by the standard.
There is a thing which a DOS/V after that understands in this
structure.
But, it seems that it was not a rare method separately to make
it indicate
a Kanji on the graphic screen even if those days were taken
because it
had already been adopted with Multi-16 of Mitsubishi Electric
corp.
An indication speed is thought to be very late with the management
speed
of the CPU having been slow when a Kanji font card isn't attached
because
there were a few memories.
In such cases as the bus and the interface
A really different individual bus is adopted with IBM PC and
MCA after that
as well.
Therefore perfectly lacks the compatibility of the Adapter
kind.
It lacks compatibility by the individual thing even if it is attached to
the
display and the keyboard.
A parallel interface lacks compatibility with the MCA machine
with a big
connector of 36 pin, too.
As for the cereal interface, the beginning was built in in
the model of the rest
by the option.
The example of the Adapter card
5250 Workstation Adapter
Note
This Adapter is the type of the old model
which 2 slot is used.
