Introduction
This is the Japanese version of DOS, commonly referred to as "KDOS". Unlike
later variants such as JDOS, KDOS didn't have an English mode, so it's possible
that it's not simply a Japanese-localized version of PC-DOS, although the
details are unclear. Similar to the current DOS/V, it worked by loading
software fonts into memory and displaying them on a graphics screen, so KDOS
included Kanji font files.
KDOS was used by the Multistation series and early MCA-based PS/55 machines
— 5570-S/T and
5550-S/T.
Version Overview
KDOS started with version 2.0, and the final version was 3.4. The models,
hardware, and software supported differed depending on the version. See the
version list for more details.
Additionally, the following localized versions were available: English,
Hangul (Korean), Simplified Chinese, and Traditional Chinese (Taiwan). The
existence of the English version is likely due to the lack of hardware
compatibility with the IBM PC.
Fonts
There were two types of fonts to match the 24-dot and 16-dot models.
For models without built-in Kanji ROM, KDOS included JIS Level 1 Kanji fonts
until the end. For JIS Level 2 Kanji and IBM-specific Kanji, a separate
software package was used.
There were separate fonts for models 5530 and 5535. It seems that no fonts
were included for the 5535 model. (Ed. not sure
what is correct here.)
BASIC Interpreter
KDOS had a built-in BASIC interpreter, which was likely based on MS-BASIC.
It had limitations like a total of 64KB program space, the inability to use
labels, etc.
Hard Disk Support
There was a partition limit of 32 MB. Therefore, for disks over 40 MB, it
was necessary to divide the drive into multiple partitions.
