Ardent Tool of Capitalism

The go-to place for all PS/2 and Micro Channel addicts. MAD Edition!

Type 5550

Introduction

It is a series to say as the main force of the Personal Computer for the business which IBM to cancellation of sales of PS/55 sold from the sales start of the Multistation.

It had the shape of the box which a system, unit is peculiar to from the first model A to the model K.

A form became the shape of the general desk-top computer with the model M/P put on the market when 5570 which is the beginning of PS/55 of the MCA machine appears.

i8086 is adopted to the model H, and i80286 is adopted after the model J.

There was a model for the export for America, too.

~~There are no materials on hand about A, B and the model C.~~
~~It guesses it more than the pattern turn of the display as follows.~~

~~Model A    16-dot Monochrome~~
~~Model B    24-dot Monochrome~~
~~Model C    16-dot Color~~

Memory

The memory of 1MB and more can be used with KDOS only as a RAM Disk.
All memories can be used with OS/2 for the program.

Floppy Drives

2DD is 720KB
2HC is 1.2MB
A maximum 3 drive can be built in except for the type with the Hard Disk.
It learned to increase 3.5-inch Drive for the media change in the rest with the outside.

Video Modes

16-dot type is indication of a 720x512 dot.
24-dot type is indication of a 1024x768 dot.

A model C is 4 colors indication in 16 colors at the time as indication of a resolution 360x512 dot.
As for the rest, 16 dot type and 24 dot type, 16 colors indication in 64 colors.

Kanji Characters

A box pattern model isn't equipped with the Kanji ROM.
The Kanji Font Card of the option is attached, or the Kanji Font of the software is read and made to indicate it.
When Diskette is 1 drive, a Kanji Font Card becomes indispensable.

Export Model

A model for the export for America is on it in the materials on hand.
The OS of each language and software are on the catalog of the software.
English,Hankul alphabet, China and Taiwan.
~~And, it seems that because there was "a model GU" in the corresponding model, one more model existed.~~
It seems that the Multistation of the Korean character edition was being manufactured in South Korean IBM. As for China and Taiwan, it isn't known at present.
