The PC-9801 is a Japanese 16-bit microcomputer manufactured by NEC from 1982, the first in the PC-98 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. As with its predecessor, the PC-88, it's abbreviated as PC-98.

Seiko Epson also manufactured PC-98 clones as well as compatible peripherals.

HardwareEdit

Although similar to IBM PCs, the PC-98 used its own 16 bit C-Bus instead of the ISA bus; BIOS, I/O port addressing, memory management, and graphics output are also different.

SoftwareEdit

The PC9801 had thousands of game titles designed for it, many of which made creative use of the system's limitations (it was originally designed as a business machine) to great commercial success. Despite having hardware specifications far inferior to the Fujitsu FM Towns and Sharp X68000 personal computers, the massive install base and steady flow of game titles (in particular "dōjin" style dating sims and RPGs, as well as early games of the Touhou Project and Valis franchise) kept it as the favored platform for PC game developers in Japan until the rise of the DOS/V clones.
