    Generally it is working for the improvement in the ability though it occurs
    to pass from the appearance rest of IBM PC for several years.

    The high resolution to indicate Japanese with 24 dot is especially
    characteristic.

    When the next high resolution standard of VGA is developed in IBM,
    the resolution of the Multi-Station was adopted.
    It is a famous story.

    As for the resolution of 16 dot edition, even the expansion indication
    mode of JX was adopted.

 The structure of indication of Kanji
    It is fundamental specifications it has the font of the Kanji, and adds a font
    to the memory more than software and to indicate it on the hardware.

    The Kanji font card of the option must be built in in this inside of the body
    by the model.

    A Kanji font card became a Kanji ROM more than the model of the middle,
    and came to be carried by the standard.

    There is a thing which a DOS/V after that understands in this structure.

    But, it seems that it was not a rare method separately to make it indicate
    a Kanji on the graphic screen even if those days were taken because it
    had already been adopted with Multi-16 of Mitsubishi Electric corp.

    An indication speed is thought to be very late with the management speed
    of the CPU having been slow when a Kanji font card isn't attached because
    there were a few memories.

 In such cases as the bus and the interface
    A really different individual bus is adopted with IBM PC and MCA after that
    as well.
    Therefore perfectly lacks the compatibility of the Adapter kind.
 It lacks compatibility by the individual thing even if it is attached to the
    display and the keyboard.
    A parallel interface lacks compatibility with the MCA machine with a big
    connector of 36 pin, too.
    As for the cereal interface, the beginning was built in in the model of the rest
    by the option.

  The example of the Adapter card

    5250 Workstation Adapter
      Note
          This Adapter is the type of the old model which 2 slot is used.
