Condition

5535 image

I got it as a junk item at a certain auction, so I can't say it's in good condition.

There are quite a few areas where the paint is peeling off, and there are some horizontal lines on the LCD. The keyboard has some unresponsive keys and the diskette drive occasionally malfunctions.


Hardware Configuration

CPU i80286 10MHz
Memory 1MB (passes the system tests)
Hard Disk 20MB
Display Monochrome LCD with backlight
Adapter 5250 Extended Workstation Adapter / LT

Hard Disk Partitions

Partition 1 ICHITARO 4MB
Partition 2 MS-DOS K3.42 16MB

It is divided into two partitions. The booted partition becomes the C drive, and the other one becomes the D drive. As far as I know, it's pretty rare for the drive letter to change like this.

Installed Software

OS KDOS Ver. K3.43 (for 5535)
Kana-Kanji conversion Partition1 ATOK6
Partition2 MKK (consecutive clause conversion)
Application ICHITARO Ver. 3.1
Emulator 5250 Japanese Personal Computer
Development language IBM COBOL/2

The 5250PC failed to start with an error that the adapter is bad.


KDOS Configuration

CONFIG.SYS of Partition 1

BUFFERS=50
FILES=20
DEVICE=C:\$LDISK.SYS 2
DEVICE=D:\DOS\SYS\ANSI.SYS
DEVICE=D:\DOS\SYS\$PRN24E.SYS
DEVICE=C:\ATOK6IB.SYS
DEVICE=C:\ATOK6IA.SYS /D=C /N=ATOK.DIC /R=0 /M=0 /T=1 /S=1 /E=1 /B=0 /C=2
SHELL=C:\COMMAND.COM /P /E:512

Free space: 467,760 bytes

CONFIG.SYS of Partition 2

BUFFERS=20
FILES=30
DEVICE=C:\DOS\$LDISK.SYS 1
DEVICE=C:\DOS\SYS\$BANKMGR.SYS
DEVICE=C:\DOS\SYS\$MKKCVT0.SYS /B
DEVICE=C:\EM5250J.SYS
DEVICE=C:\DOS\SYS\$CLOCK.SYS
DEVICE=C:\DOS\SYS\$PRN24E.SYS
DEVICE=C:\DOS\SYS\ANSI.SYS
SHELL=C:\COMMAND.COM /P /E:2048

Free space: 489,248 bytes

CONFIG.SYS for each partition has the above settings. Since this is an old version, there is no HMA or UMB, but there are quite a few free areas because it has a built-in Kanji ROM.

Here, I would like to explain the drivers specific to KDOS and JDOS.

$LDISK.SYS A driver for recognizing logical partitions.
The partition with the specified number is made available as a drive. When you boot from the second partition and set $LDISK.SYS 1, the first partition is available as the D drive.
$BANKMGR.SYS A driver for using memory banks.
The memory bank support remained to JDOS Ver. 4.
$MKKCVT0.SYS Driver for multiple-clauses conversion.
The /B switch lets you use memory banks.
EM5250J.SYS Driver for the 5250PC adapter.
$CLOCK.SYS Time display driver.
The current time is displayed at the bottom right of the screen.
$PRN24E.SYS Driver for 24-dot IBM printers.
