The PC-9801 is a computer released by NEC in 1982, and the first computer in the PC-9800 series.

Hardware

The PC-9801 was envisioned as a high-end business machine by NEC, being built around a 16-bit µPD8086 processor (NEC's version of Intel's 8086) and two µPD7220 graphics chips, developed by NEC to efficiently display the kanji character set (at a high enough resolution to read). In this original setup, one is used for graphics, and the other for text.

This PC-9801 shares much in common with the original PC-8801, released a year prior, expecting that the user purchase external disk drives in order to interface with the machine. No operating system is built-in to the unit (unlike the PC-8000 series, PC-6000 series and the PC-8800 series), and as these models did not ship with a hard drive, a boot disk (such as CP/M or MS-DOS) is usually required, meaning disk drives were usually sold in pairs.

While not strictly designed for gaming, its popularity in business inevitably led to video games being produced for the system (not dissimilar to the IBM PC in the West). The PC-9801 has higher resolution graphics than most of its contemporaries, but is limited to 8 colours. Much like the PC-8801, sound hardware is limited to a simple "beeper".
