The characteristics of the software It explains about the characteristics in the software of the Multistation 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. Page Top 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.
Page Top 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. The example of the partition name Japanese DOS JPC Bunsyo Program(Word Processer) JWP 3270 Kanji Emulation 3270 EM OS/2 OS/2 Logical 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. Capacity of the partition of Japanese DOS
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.
When the version of program is 5 or more What is used from the following tables is chosen, the capacity for documents is applied to this, and the capacity of the whole partition is determined.
Capacity of the partition of 3270 Kanji Emulation The minimum size is 1932KB and an idiom dictionary also enters into this. Capacity of the partition of OS/2 Ver.1.0 The minimum size is about 7MB. Page Top 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)". Page Top Index |
