Multistation Software Characteristics
|
|
Characteristics of the Multistation software are explained here.
The indication of the Kanji
Memory Bank
The use of the Hard Disk
The software which doesn't use DOS and DOS
The indication of the Kanji
It began to read a font in software, and it was a structure
【 the present DOS/V
that it is indicated in the graphic VRAM above 】 without
taking fundamental
design and using special hardware for the indication of
the Kanji.
Attention
When Diskette only took a drive, the installation
of the Kanji font card of the
option was indispensable.
The file of the font was surely in the software which
had the function of the
OS or the OS by this design.
As for DOS, the document program and 3270 kanji emulation,
it prepared for
respectively another software in the one for 24 dot and
the one for 16 dot.
5250 kanji emulation was for 24 dot, monochrome model.
When this software was used, you had to increase exclusive
font cards.
DOS had only JIS the First Level Kanji by the standard.
You had to purchase the font of the option when JIS the
Second Level, IBM
Expansion Kanji were used.
Every time it underwent a model change in the rest, it
came to be carried on
each series one after another as to the standard, and it
disappeared to
begin to read a Kanji font more than software.

Memory Bank
When DOS was used, Memory Bank of the individual specifications
could be
used.
A multiplex memory adapter was used at the initial type,
and a part of the
increasing memory could be allocated to Memory Bank in
the latter term
type.
There was Memory Bank from 0 to 3, and the size of 1
bank was 384KB.
The number of bank to use by the software was decided.
Bank 0 is equivalent in the upper part more than 256KB
of the main memory.

The use of the Hard Disk
"The Hard Disk Initialization Program" of the
exclusive use attached when a Hard
Disk is used in the Multistation was necessary.
A format did a Disk by using this program, and a partition
was made, and
software was introduced.
The capacity of the Hard Disk which can be supported
depended on the version
of the software.
It couldn't be set up if the name decided as the partition
to introduce software
wasn't given.
A name could be changed after the introduction.

Partition
OS/2 * (ex. "OS/2 DATA")
It was chosen which partition to start from at the time
of the start unless the
partition which did an automatic start was set up.
Unlike the computer of present IBM, the same disk could
take more than one
same software, too.
Here is a thing which is closer to the PC-98x1 series
of NEC than a IBM PC.
And, it could be taken to the maximum 8 partition.

The capacity of the partition which can be treated
by DOS beyond version K2.6
was a maximum of 32MB.
Capacity of the partition of Japanese word processor
The minimum value required for a partition in case the
version of a program is
less than 5.
If a larger partition than this table is taken,
the capacity which can be used for
documents will increase.

The minimum size is about 7MB.

The software which doesn't use DOS and DOS
As for the Multistation, "one unit 3 post",
in other words
A Personal Computer as to Japanese business
Japanese word, processor
The terminal of Japanese on-line system
There was meaning to change a function by one unit and
to use it.
These three functions worked as another system at the
time of the appearance,
and it was not the condition that the top of the OS had
all software like the present.
Each partition was necessary when a hardware, disk was
used.
The example of the software which doesn't use DOS
Bunsyo Program(Word Processer)
3270 Kanji Emulation
5250 Kanji Emulation
You had to do a data change therefore to share data with
the software on DOS.
One of such software had "File Conversion Utilities (PC-WP)".
