The PC-9801 is a Japanese 16-bit microcomputer manufactured by NEC from 1982, the first in the PC-9800 series of 16-bit and 32-bit personal computers. The platform established NEC's dominance in the Japanese personal computer market, and by 1999, more than 18 million PC-98 units had been sold. == History == It first appeared in 1982,〔 Reprinted from 〕 and employed an 8086 CPU. It ran at a clock speed of 5 MHz, with two µPD7220 display controllers (one for text, the other for video graphics), and shipped with 128 KB of RAM, expandable to 640 KB. Its 8-color display had a maximum resolution of 640×400 pixels. Its successor, the PC-9801E, which appeared in 1983, employed an 8086-2 CPU, which could selectively run at a speed of either 5 or 8 MHz. The NEC PC-9801VM used NEC V30 CPU. When the PC-98 was launched in 1982, it was initially priced at 298,000 yen (about 1,200 USD in 1982 dollars). In the 1980s and early 1990s, NEC dominated the Japan domestic PC market with more than 60% of the PCs sold as PC-9801 or PC-8801. In 1990, IBM Japan introduced the DOS/V operating system which enabled displaying Japanese text on standard IBM PC/AT VGA adapters. After that, the decline of the PC-98 began. The PC-9801's last successor was the Celeron-based PC-9821Ra43 (with a clockspeed of 433 MHz, using a 440FX chipset-based motherboard design from 1998), which appeared in 2000. While NEC did not market these specific machines in the West, it did sell the NEC APC III, which has similar hardware as early PC-98 models.〔(【引用サイトリンク】url=http://www.old-computers.com/museum/computer.asp?c=996&st=1 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「NEC PC-9801」の詳細全文を読む スポンサード リンク
