The PC-8001 MKII SR was the last one of PC-8001 Series. In 1985, PC-8801 series took the place of the PC-8001 series along with a large amount of available software, so this computer didn't meet a large success.
This machine displayed not only Katakana but also Hiragana characters, a Kanji-ROM was available as optional extra.
