At one of the standard of Direct RDRAM, the specification which corresponds to the memory clock to 800MHz. As for RIMM1600 standard of memory module, as for PC800 it is standard of the memory chip which corresponds.

As for maximum data rate with 1.6GB/s, equality to the PC1600 standard of DDR SDRAM. As for the chip set which such as i840/i850/i860 corresponds to many RDRAM 2 collecting PC800 corresponding memory, it utilizes (dual channel) for the sake of, maximum data rate in this case becomes 3.2GB/s. There are also times when the value, this 3.2GB/s is made the maximum data rate of PC800, but with memory module 1 as a maximum data rate it is inaccurate.

NEC from the eighties betting on nineties first half, the personal computer which was sold. With general term of the PC-9821 series of the PC-9801 series and the succession, you were proud of the preponderant share of the extent which is called the “national machine” in mature stage.

The first generation PC-9801 was sold in 1982 October as the NEC make personal computer and a succession type of PC-8801 series similarly. This the same company first 16 bit microprocessor (the Intel corporation 8086) with the personal computer which is loaded, has loaded the Kanji ROM, Japanese was easy to handle.

In addition, powerful word-processing program “Ichitaro” was sold in for PC-9801, accompanying the spread of the personal computer to the office could sell well.

Type name of the NEC personal computer, in addition, name of the series which is connected to that. Series first type “PC-9801” was sold in 1982 October. In CPU Intel 8086 (clock 5MHz) with 16 bit personal computer which is loaded, as for memory 128KB.

The PC-9801 series has loaded the Kanji ROM, because Japanese is easy to handle, accompanying the spread of the personal computer to the office it could sell well.

The bus and the I/O controller etc inside are most individual standards, the slot of the especially extended functional board is called C bus. In zenith period, the extended functional board was sold many even from the third party.

The PC-9801 series occupied the preponderant share of the extent which is called the “Japanese national machine”, over 10 years or more, but with the spread of Windows of the Microsoft corporation, it kept moving to the PC-9821 series, and the PC-98NX series of the superior type.

NEC series name of the personal computer which it announces from 1993, as the superior interchangeable type of PC-9801 series. It is large separately, “MATE” “MULTI” (CanBe after) there are 3 systems “of VALUESTAR”.

The MATE series built-in CD-ROM drive (option) and, is the series which strengthens, multimedia performance such as graphic correspondence and FM sound source PCM sound source loading above VGA.

Furthermore among those in announcement chronological order, there are 4 series which have the type turn of A?B?X?R, in type of latter term such as X and R, type of high specifications such as loading the PCI bus and adopting the P6 architecture is many.

The personal computer which the IBM corporation sells in 1984. Because many of internal specification are released, the interchangeable product was sold from each company, became in fact worldwide standard. Because the personal computer where presently MS-DOS and Windows operate has succeeded the design of this computer, naming generically those, there are times when it calls the “PC/AT compatible machine”.
