The platform established NEC's dominance in the Japanese market, and by 1999, more than 18 million PC-98 units had been sold.

PC-9801F motherboard The first model, the PC-9801, was launched in October 1982, and employed an. It ran at a of 5 MHz, with two display controllers (one for text, the other for video graphics), and shipped with 128 KB of, 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 -2 CPU, which could selectively run at a speed of either 5 or 8 MHz.

In the 1980s and early 1990s, NEC dominated the Japan domestic PC market with more than 60% of the PCs sold as PC-9801. In 1990, Japan introduced the which enabled displaying Japanese text on standard adapters. After that, the decline of the PC-98 began. The PC-9801's last successor was the -based PC-9821Ra43 (with a clock frequency of 433 MHz, using a 440FX chipset-based motherboard design from 1998), which appeared in 2000.
NEC kept much of its hardware and platform proprietary or under license, so while it had a virtual monopoly in the Japanese market, later IBM PC clones with DOS/V and Windows from companies such as and that did not require such license fees (like Epson's 98 clones) flooded the market and displaced NEC. [ ] Hardware [ ] The PC-98 is different from the IBM PC in many ways; for instance, it uses its own 16-bit C-Bus () instead of the bus;, addressing, memory management, and graphics output are also different. However, localized or will still run on PC-9801s. Expansion bus [ ].
4 MB memory board for C-Bus Many PC-9801 models could increase system memory by expansion boards, daughterboards, or proprietary. They were limited to 14.6 MB, due to 24-bit address pins and reserve space.
Memory boards for C-Bus were also available. The PC-9821Af introduced in 1993 shipped with standard 72-pin SIMMs, broke 14.6 MB barrier and supported memory up to 79.6 MB. Later desktop models shipped with standard SIMM or memory. Storage [ ] Early PC-9801 models supported 1232 KB 8-inch and/or 640 KB 5¼-inch floppy drives. Each used different lines and I/O ports.
Later models supported both interfaces. 5¼-inch and 3½-inch HD floppy disks used the same logical format and data rate with 1232 KB 8-inch floppy disks.
They became a non-standard format while formats brought by IBM and became industrial standard. Craagle serials list. The PC-98 supports up to four floppy drives. If the system is booted from a floppy drive, MS-DOS to all of the floppy drives before considering hard drives; if booted from a hard drive, it will do the opposite.
If the OS was installed on the hard drive, MS-DOS would assign the hard drive as drive 'A:' and the floppy as drive 'B:'; this would cause incompatibility among Windows PC applications, although it can be resolved with the SETUP command in Windows 95, turning on the '/AT' switch to assign the Windows system drive to the standard 'C:' drive. The PC-98 used several different interfaces of hard drives. Early models used (SASI), and later models used SCSI or drives. Graphics [ ]. Drawing 8 color characters and 16 color background.
A standard PC-98 has two display controllers (a master and a slave) with 12 KB main memory and 256 KB of video RAM respectively. The master display controller handles font, displaying (7x13 pixels) and (15x16 pixels) characters. Each character had a variety of display options, including bits for secret, blinking, reverse, underline and three intensity bits (grayscale or RGB). The other display controller is set to slave mode and connected to 256 KB of video memory, allowing it to display 640 x 400 pixel graphics with 16 colors out of a palette of 4096. The video RAM is divided into pages (2 pages x 4 planes x 32 KB in 640x400 16 colour mode), and the programmer can control which page is written to and which page is output.
