NEC PC-9821
Die NEC PC-9821 Computer sind 32-Bit-Desktopcomputer der PC-98-Modellreihe (auch PC-9800-Modellreihe) des japanischen Unternehmens NEC von 1992 bis 2000. NEC brachte von 1992 bis 2000 etwa 140 verschiedene PC-9821-Modelle heraus, die meisten davon von 1994 bis 1997.[1]
Im Jahr 1991 begann in Japan der Marktanteil der 98-Computer bei den PC-Neukäufen zu sinken. Daher erschuf NEC 1992 den "PC-9821"-Standard als Antwort auf die so entstandene Bedrohung ihrer Vormachtstellung in Japan durch IBM-kompatible Computer. Der PC-9821-Standard kombiniert die volle Kompatibilität zur eigenen PC-98-Familie mit einzelnen Features aus der IBM-kompatiblen Welt. So kann er mit einem trimodalen 90 mm-Diskettenlaufwerk auch das IBM-kompatible 1440-KiB-Format lesen, bietet erweiterte Graphikmodi analog zur VGA-Karte und bei manchen Modellen auch ein PCI-Bus neben dem eigenen C-Bus. Im Jahre 1995 überstieg der Anteil der IBM-kompatiblen DOS/V-PC zusammengenommen erstmals denjenigen der PC-98-Computer. NEC stellte daher die Produktion der "klassischen" PC-9801-Modelle 1995 ein, die Produktion der PC-9821-Modelle lief aber weiter. Im November 1997 gab NEC die geplante Aufgabe ihrer gesamten PC-98-Palette bekannt. 1998 begann NEC mit der Produktion ihrer PC-98NX-Serie, die DOS/V-kompatibel ist. Die letzten neuen Modelle der PC-98-Familie erschienen im Mai 2000, es war das Notebook PC-9821 Nr300 "Lavie" und der Desktopcomputer PC-9821 Ra43.[1]
