The NEC PC-100 was a Japanese home computer available on October 13, 1983. It operated on 8086 CPU 7 MHz, 128KB RAM, 128KB VRAM, a Japanese language capable keyboard and a two button mouse. It had three models and its color monitor, PC-KD651, which could be used vertically or horizontally, had the price tag of 198,000 yen. Its biggest advantage over other computers of that time was its high graphical capability of 720 by 512 with a selection of 16 color out of 512 color available on its high end model30. Its OS was MS-DOS and was also equipped with a spreadsheet program Maruchipuran (Multiplan) and a text editor JS-WORD as well as the game Lode Runner. The development was operated by NEC Electronic Device Business Group, ASCII (Microsoft dealer in Japan) and Cybernet Kogyo, a subsidiary of Kyocera.

The Electronic Device Business Group launched the PC-8001 in 1979, making NEC the biggest PC vendor in Japan. However, the Japanese personal computer industry had just begun, and it was unclear which market would grow. Other large computer manufacturers, IBM Japan and Fujitsu, had not focused on the personal computer industry yet. Hitachi and Sharp released home computers for hobbyists.
